Euthanasia and Religion Essay -- Papers

Euthanasia and Religion Some people believe human life is to respect above all other forms of life whilst others believe that all life (both human and non-human species) is to be given equal respect and treated as 'sacred' (special). Most religions believe humans are special. For instance, they teach that we have a soul (a part of us that lives on after death), and that we have been given an opportunity to have a relationship with God. Some religions, such as Judaism and Christianity, also teach that humans have been created in 'God's image'. This means that humans have certain qualities and characteristics that God has (E.g. They can make things, they have the ability to reason things, they were created good). It is also believed that humans have been given a responsibility to look after the world God created. The following passages from the Bible illustrate the special nature of humans 'Then God said, "Let us make man in our image, in our likeness, and let them rule over the fish of the sea and the birds of the air, over the livestock, over all the earth, and over all the creatures that move on the ground. So God created man in his own image, in the image of God he created him; male and female he created them' (Genesis 1:26-27) '... What is man that you are mindful of him, the son of man that you care for him? You made him a little lower than the heavenly beings and crowned him with glory and honour. You made him ruler over the works of your hands; you put everything under his feet.' (Psalm 8:4-6) Christians also believe God values human life greatly as they believe Jesus came to die to heal the broken relatio... ...e had a pet that developed an incurable illness we would believe it cruel to keep it alive. To stop it suffering and not having a good life we would take it to the vet to have it 'put down'. Yet surely if humans are nothing more than 'cleaver apes' why not 'put humans down' when they develop incurable illnesses or when their quality of life deteriorates? Why do we hold human life special in that we want humans to be treated differently to the way we treat animals? Has evolutionary theory left us with a problem? On the one hand some people want to reject the idea that God exists, and is the creator of humanity, yet on the other hand they want to say that human are different to other 'animals'. Yet is it possible to reject God whilst retaining the view that human life is more valuable than the lives of other 'animals'?

Giving Language Back:An Argument Against Isolated Grammar Instruction :: Argumentative

Giving Language Back:An Argument Against Isolated Grammar Instruction Who knew that kids liked to read? I certainly didn’t. Let me qualify that. I have known a few kids that liked reading. My daughter likes to read, but I assumed she would, being the daughter of an obsessive reader and all. I have known other child-readers through the years, but since they were nerds like me, I never guessed that â€Å"normal,† MTV-watching, note-writing, gum-popping, 20/20-visioned kids would like to read as well. Fortunately, during my student teaching experience, my classes of seventh-graders proved me wrong. Before delving further into my experience at Freedom Middle School, it is important to understand the significance of my students’ reactions to good literature and to an isolated, grammar-based unit. In this paper, I will not only relate my personal experiences with the two types of curriculum, but what educators and researchers have said about them. Throughout this exploration of time-tested opinion and heavily researched facts, however, the underlying concern will always be our goal in teaching children. Should we try to force them to be who we think we should be – whether our intentions are based on an allegiance to the superiority of traditional methods or on an assumption of the inferiority of our students? Or should we try our hardest to help the students become their own individuals, only better? The first few weeks of students teaching went very well. I had few discipline problems, and the students were very engaged during class time. In fact, they seemed eager to come to class! While I could have credited my wondrous teaching style for their interest, I knew that that was not the reason. In reality, their usual Language Arts angst disappeared because they thoroughly enjoyed the novel we were reading in class, The Watsons Go To Birmingham – 1963. While I had to wake a few dozers and intercept a few notes here and there, all of the students followed along as I read aloud or we listened to a recording of Lavar Burton reading the novel. I saw at least twelve students that were actually reading ahead of their classmates. And while they probably would have preferred discussing music videos or cars, they eagerly summarized chapters when asked and often told me what they would have done if they had a brother like Byron or visited Birmingham in the 1960s.

Fitness program for Football

Many things affect your performance in games. Training preparation and fitness definitely affect your performance in games this is because when you train you improve everything needed to play football. If you exercise and train on cardiovascular endurance therefore you can last a whole game without tiring which is great because then you can play without the team having the strain of carrying you through the match. So if you train you become fitter if the training involves steady progression, this will enable you to play the game without tiring or straining yourself to hard. The better and more you exercise won't just affect your fitness it affects all three aspects of your health. The three aspects of health are social, mental and physical well-being. If you do exercise the social well-being would improve because you go to classes and meet people and make new friends so exercise = more friends+ and greater social well being. Exercise helps your mental well-being because you deal with stress and new skills and tactics giving you focus and determination. It also helps when the day is bad for oneself you can go out and relieve stress and tension that has built up during the day. Exercise helps physically because overweight people burn body fat and skinny people build muscles and give them a nice shape. It also prevents heart disease and high blood pressure, back pain and some cancers. Swimming and walking help people with asthma and all this gives a higher life expectancy so exercise looks good for everyone but too much can cause illness and make you more susceptible to flu. The reason for training is to improve your ability to take part in physical activity. Training has certain principles that apply no matter no matter what sport you undertake. These are: (S) Specificity (P) Progression (O) Overload (R) Reversibility (T) This is there because it is a simple way of remembering the principles of training Specificity Any type of training must be suitable or specific to the activity that you are training for E.g. A strength building programme will not train your body in order to run a marathon. Aswell as choosing a type of training you may wish to train concentrate on part of the body too E.g. strength building on the legs. SPECIFIC EXERCISES WILL NOT PRODUCE SPECIFIC RESULTS Each activity will have different specific demands. Most physical activities require a combination of exercises and it is important to analyse exactly what is required and those requirements can be met. It will even be necessary to identify relevant muscle groups. Overload This is making the body work harder than normal in order to improve it. Overload can be achieved in the following ways. Frequency of training: To start with you may only train twice a week with a recovery period in between. This could be increased to every other day and then to five times a week to create overload. Intensity: You can increase the intensity by simply working harder at the training method you are using e.g. twenty minute jog at 50 % of max speed increased to twenty minute jog at 60 % of max speed. Time/ Duration: Refers to the length of each training session and this should be made longer to achieve overload. Unfortunately we can't increase the time of each session because we are confined to lesson times. Your body responds to overload by adapting to it. Used sensibly it will lead to an improvement. Progression The training you are doing and particularly the amount of overload must be increased progressively. In other words, as your adapts to the increased demands that you are putting on it, then that demand should be steadily increased. If you sty at the same level so will your fitness, but you must not do too much too soon, this will lead to injury. Reversibility If you either stop or decrease your training you go into reverse and lose the effect. There are three heart rate zones they are normal, which is below 60% of your highest heart rate and there is aerobic respiration, which is above 60% of your max heart rate, and below 85% of max heart rate then there is anaerobic respiration, which is above 85% of max heart rate. When your heart rate is normal this means no benefit from training so this is bad so I have to make myself go above 60% of my max heart rate for someone my age because everyone has a different heart rate. It is believed that your max heart rate is 220- your own age e.g. 220 – 15 = 205 beats a minute which is extremely fast therefore 123 is my aerobic point and 174 is my anaerobic point. A way you can see your anaerobic point is on this graph: To make my fitness programme effective for my current level of fitness I will use many bits of information gathered such as the results from nine fitness tests preformed in class times also I will use whether recent illness has effected my performance of late. The results were in a table like this one: This table shows that I had an average attempt but can improve in allot of areas so I will focus on these areas. The areas that most concerns me is co-ordination and reactions this is because they are needed most of the time playing football e.g. when I need to dribble and look up for options so this is good when a cross can get into the box. Reactions are needed in football when the ball can't be seen when it is crossed then at the last minute you see it and need to control it. So in my programme I will be using this information to get these different fitness components improved. Over the last two weeks I have had lots to eat this being bad food for fitness because it is that time of year so this may effect my ability at the start of the course. I have had no real illness but the slight illness has now gone and I am back to normal and fighting fit. My football skills always need to be improved so I will use practices to improve passing and shooting techniques so these will be included to my fitness programme. Also I will do a little on control because it makes no harm practicing that. You should always do a warm up before each main activity because it is light exercise to get the blood pumping around the body. Also during a warm up your muscles get by the blood flowing around them gets faster and this lowers the risk of injury. The warm up also heats up synovial fluid this makes joints more mobile. When stretching in a warm up this helps muscles, tendons and ligaments from getting strained. When doing simple skills this your muscles but also helps psychologically. So this light exercise helps all three elements of health if doing in a group. In a good warm up before any sport there should be three main phases a gross body movement stage where by you do simple jogging for a long time doing such things as bringing your knees up to your chest, flicking your bottom with your heels then when you feel it is good gradually get faster into sprinting. This is to get the blood pumping around your body this also may improve slightly on cardio vascular endurance. Remember go from slow to a faster speed. My gross body movement arrangement can be shown in this diagram: The second stage of any warm up should be stretching this will help loosen the main joints this also helps to stop muscles, tendons and ligaments straining. The stretching phase should start from your ankles upwards stretching nearly every muscle. To improve flexibility you should stretch from 10-30 seconds and doing it regularly should be 8-10 seconds. The stretches used should be one as these: The next stage in the warm up is the skills stage, which helps the psychological side giving focus and determination. In this stage there should be simple tasks, which involve skills needed in a game e.g. passing against the wall controlling it and passing again and other various simple tasks. After the main activity there should be a cool down this should be included because helps your body recover after vigorous activity. Like the warm up this has phases but only two they are gross body movement and stretching. The gross body movement stage this time is to give oxygen to the muscles meaning lactic acid can be removed thus giving the muscle less stiffness. During the warm up you go from slow to fast this time go from fast to slow. Use many of the techniques shown in section five on the warm up. Finish off the cool down with some stretches this should loosen your muscles and prevent stiffness because usually after exercise muscles are often tight. As before in the warm up go from ankles upwards. Use the stretches shown in the warm up section. To monitor my performance of my activities in the 6 sessions I will use this table: I have used this table because it sets a target for each session and shows how close I was to meeting the target so if my sessions are good I should reach the target easily each time. I will make sure that the area is safe for others and myself. I will pack things away and leave them in safe places and make sure they are out of the way. I will try to set up things in an area that is out of the way of other people so noone is harmed. I will put things away immediately away after use. I will wear suitable clothing that is easy to do all the activities required.

IPv6 is the next-generation Internet protocol that will replace IPv4, providing a vastly expanded address space. This white paper provides an update on the current industry status of IPv6, how the IPv4 to IPv6 transition will affect some organisations, and Telstra’s perspective on the transition. Internet Transition IPv4, the dominant addressing protocol, is rapidly running out of capacity and will be replaced by IPv6The protocol that governs communication on the Internet (and most intranets) today is called Internet Protocol version 4, or IPv4. The popularity of the Internet has caused a shortage of public IPv4 addresses and they are quickly running out, with the glo bal registry of IPv4 addresses from the IANA (Internet Assigned Numbers Authority) exhausted in February 2011 and the Asia-Pacific regional registry in April 2011I. Other Regional Internet Registries (RIRs) are expected to be exhausted between 2012 and 2014II. Once this happens, no more IPv4 addresses will be allocated to Internet service providers (ISPs).Individual ISP run-out will depend upon how well each ISP manages its address pools compared to the rate of each ISP’s subscriber growth. The transition from IPv4 to IPv6 is a popular issue and one which the industry will spend more time managing in the coming years. The transition is complex and will require IPv6 support by an end-to-end industry ecosystem. The ecosystem includes customer premise equipment, modems/home gateways, network systems, management (OSS/BSS, tools), content and applications. Telstra’s Approach Telstra’s approach is based on the dual-stack solution, allowing both IPv4 and IPv6 addresses to co-existTelstra will ensure that customers can migrate to IPv6 at their own pace, with minimal impact to services Telstra has been planning for the IPv6 transition for a number of years. We have a defined transition strategy and a well-advanced IPv6 implementation program. Our strategy for IPv6 introduction is based on the dual-stack solution, allowing both IPv4 and IPv6 addresses to co-exist until the transition to IPv6 is complete. This approach will make sure that the transition occurs with minimal impact to customers. Customers will not be forced to move to IPv6 overnight – they can deploy and migrate to IPv6 as they become ready.Telstra is already testing dual-stack technology on a number of key networks and products to seamlessly introduce IPv6. Similar to service providers, businesses face a challenge in undertaking the complex transition of their IPv4 internal ecosystems without impacting services. Just as Telstra has done, it is advised that every online or IT-ba sed business should prepare an IPv4 to IPv6 transition strategy. Telstra will provide timely information and updates on our own program of work to assist customers, suppliers and others in the industry to manage their transition. 3 WHAT IS IP v 6?IPv6 was designed during the mid-1990s, when the Internet Engineering Task Force (IETF) realised that IPv4 address size constraints would soon be a major impediment to the continued growth of the Internet. IPv6 was first known as the Next Generation Internet Protocol (IPng) during development within the IETF. Since 1998, it has officially been known as IPv6. In the transition to IPv6, both IPv6 and IPv4 will co-exist until IPv6 eventually replaces IPv4. The most obvious difference between IPv6 and IPv4 is the vastly expanded IP address space available The most obvious difference between IPv6 and IPv4 is the address size.IPv6 addresses comprise 128 bits, whereas IPv4 addresses comprise 32 bits. This difference results in a huge expansion in available IP address space: ? I Pv4: 2 32 a ddresses equals 4. 3 billion addresses (less than the global human p opulation of 4. 7 billion) ? I Pv6: 2 128 a ddresses. Because the last 64 bits are used to allocate a ddresses within a subnet, that leaves 2 64, which equals 18 billion billion s ubnet addresses. IPv6 is not backwardly compatible with IPv4 Whilst IPv6 performs the same address function as IPv4, IPv6 is not backwardly compatible with IPv4. Therefore, an IP data session must use either IPv4 or IPv6 end-to-end.IPv6 and IPv4 can be used together with translation mechanisms such as Application Layer Gateways when the applications are known and supported end-to end. 4 IP v 4 ADDRESS RUN OUT The global top-level registration body, IANA (Internet Assigned Numbers Authority), exhausted its supply of available IPv4 addresses in February 2011. APNIC (Asia Pacific Network Information Centre) is the Regional Internet Registry which allocates IP addresses in the Asia-Pacific region. U nfortunately for Australia, APNIC effectively ran out of addresses in April 2011. The Asia-Pacific is also the highest growth region for IP address llocation. Telstra and any other ISP in the Asia-Pacific region are now only eligible for a total allocation of 1024 further addresses from APNIC. There will be no further large allocations of IPv4 addresses for Asia-Pacific ISPs Because no further large allocations of IPv4 addresses are available, the ability of Asia-Pacific ISPs to allocate IPv4 addresses for new customers depends on the number of addresses they already hold, the rate at which they are using them for new services, and the ISP’s capability to adopt address translation technologies, which may reduce their rate of address demand.These factors will be different for each ISP, so it is likely that ISPs across the industry will run out of IPv4 addresses across a wide timeframe – some may run out within only a couple of years, others may be able to delay that exh austion well into the future. 5 WHAT HAPPENS WHEN IP v 4 ADDRESSES RUN OUT? Internal enterprise networks using private IPv4 addresses will not be affected IPv4 and IPv6 will co-exist on the Internet for many years Firstly, internal enterprise networks using private IPv4 addresses will not be impacted.Nor will the run-out impact existing IPv4 networks and IPv4 based services already allocated IPv4 addresses — they will continue to operate normally. Secondly, IPv4 and IPv6 will co-exist in the Internet for many years, quite likely for decades. Unlike Y2K, there is no cut-off date when IPv4 use will cease and the world will fully migrate to IPv6. The plan is for gradual transition: different regions and industry players will move to IPv6 at different rates. Consequently, end users will need the capability to access both IPv4 and IPv6 content and services on the Internet. This dual apability may be inherent in the end users’ equipment, or may be provided transparently by t heir or the content publishers’ ISPs. To enable this dual protocol access during the transition period, technology solutions were developed in conjunction with the development of the IPv6 protocol in the mid-1990s. Three categories of transition technologies exist: ? Tunnelling – encapsulates one protocol within another (e. g. IPv6 in IPv4, IPv4 in IPv6) ? Protocol Translation – translates packets between protocols (e. g. IPv6 to IPv4) ? Dual-stack – support both protocols in parallel within one network. Telstra’s dual-stack path nables both protocols to co-exist on our networks Telstra has chosen the dual-stack path, enabling both protocols on its networks. The use of dual stack will ensure our customers have the current functionality of IPv4 always available to them even while they start deploying IPv6 in their systems. The transition from IPv4 to IPv6 is a known issue which the industry will have to manage over the coming years. The transition w ill take time as it will require IPv6 support by an industry end-to-end eco-system including CPE, modems/home gateways, networks, systems (OSS/BSS, tools), content and applications.Figure 1: IPv6 Ecosystem Systems & tools Carrier/ ISP Client apps Consumer electronics Modems Operating systems Mobile handsets Public IPv6 Content/Apps Global Internet Network vendors Content/Apps Systems & tools Servers IPv6 is the accepted solution, however, moving the entire ecosystem to IPv6 will take many years Source: Telstra 6 WHAT HAPPENS WHEN IP v 4 ADDRESSES RUN OUT? Telstra continually monitors industry developments with regard to the other transition technologies and we may choose to apply other methods where appropriate. Co-existence of IPv4 and IPv6Dual-stack (IPv6/IPv4) remains the accepted industry direction for the introduction of IPv6. Tunnelling has sometimes been used by early IPv6 adopters where native IPv6 has not been available end-to-end. IPv4 to IPv6 protocol translation mechanis ms may also be applied in the future in certain circumstances. Figure 2: Dual-stack supports both protocols in parallel within one network Applications TCP/UDP IPv6 IPv4 Physical Layer Dual Stack Backbone Applications TCP/UDP IPv6 IPv4 Physical Layer 7 GOVERNMENT MANDATES Some Governments have set mandates to ensure a well-managed transition rom IPv4 to IPv6 before IPv4 addresses run out The importance of continued Internet growth has been recognised by many governments due to its critical role for areas such as e-commerce, healthcare services and public information dissemination. This has led some governments to set IPv6 technology mandates to ensure a well-managed transition from IPv4 to IPv6 prior to the run-out of IPv4 addresses. The smooth and ordered adoption of these technologies will ensure continued Internet connectivity for all of their citizens. Initially targeted at enterprises, institutions and government elated Internet services, IPv6 mandates are now being issued for consumer broadband services The technology mandates have been primarily targeted at enterprises, institutions and departments that provide governments with their Internet connectivity services. Only recently IPv6 mandates for consumer broadband services have been issued. North America In August 2005, the US OMB (Office of Management and Budgets) issued Memorandum M 05 22: Transition Planning for Internet Protocol Version 6 (IPv6). This sets the US Federal Agencies a hard deadline for compliance to IPv6 on their core IP networks.This mandate led many major US Service Providers (e. g. AT&T, Sprint, Verizon, QWest, NTT America) to develop government and enterprise solutions to allow agencies to buy IPv6 products and services to meet their core connectivity requirements. In practice, all of the agencies met the mandate because they were able to demonstrate that their backbone networks were capable of carrying IPv6 packets by the agreed deadline. However, there was no need to actually im plement IPv6-based services. A draft roadmap for IPv6 adoption by the US Government has recently been prepared. EuropeThe European Commission communicated an IPv6 action plan in May 2008. The target was to have 25% of European customers accessing the Internet using IPv6 by 2010, which challenges all players (ISPs, content providers, customer premise equipment vendors, governments and organisations) to work towards this target. Asia Many Asian countries, including China, Japan and Korea have been early adopters of IPv6 due to government mandates. For example: ? C hinese Government Strategy: C hina Next Generation Internet (CNGI) sets o ut a five year plan (2006-2010) for the adoption of IPv6 Korean Government Strategy: T he Korean Government has the strategic IPv6 Promotion Plan II, which sets a vision of deploying IPv6 for the public sector. 8 GOVERNMENT MANDATES Australia The AGIMO (Australian Government Information Management Office) has set the following timeframes for IPv6 adopt ion within the Australian Government and its departments: ? Preparation Jan 2008 – December 2009 ? Transition Jan 2010 – December 2011 ? Implementation Jan 2012 – December 2012. The Australian Department of Defence has also mandated a move to IPv6. 9INDUSTRY READINESS FOR IP v 6 Industry has been slow to adopt IPv6 since few commercial drivers exist Across the globe, the industry has been slow to adopt IPv6, since very few commercial drivers for migration have existed at present. By its very nature, the Internet involves a huge number of disparate groups and thus a coordinated approach is difficult to achieve. The lack of a commercial imperative is due to a ‘chicken and egg’ situation: why support IPv6 in the equipment if there are no IPv6 services, and why create an IPv6 service if nobody can use it?This situation is now changing with the occurrence of the global IPv4 exhaustion. Nevertheless, while many parts of the industry are now supporting IPv 6, others are lagging behind. The following is a brief analysis of the readiness of key industry sectors: Network Equipment Generally, network equipment vendors already provide IPv6 dual-stack support In the main, network equipment vendors already provide IPv6 support (dual-stack) for the core and edge of networks. Key vendors have been hardware and softwareready for several years, with equipment deployed in small-scale trials.Even though IPv6 capability has existed in most network routing equipment for some time, it has often not been enabled for use. Network control path functions like DNS, DHCP and RADIUS, however, are not yet uniformly supported for IPv4/IPv6 dual-stack across all vendors. These remain among the ‘work in progress’ issues for the industry. Internet Infrastructure Global IPv6 interconnectivity is now growing rapidly Global IPv6 Backbones As IPv4 and IPv6 do not interwork, it is essential there is global IPv6 interconnectivity similar to the IPv4 Inter net today. The global network of IPv6 interconnectivity is now growing rapidly.We expect there will be a substantial interconnected Australian IPv6 backbone between many, if not most, ISPs by the end of 2011. Domain Name Servers IPv6 devices will resolve Internet domain names into IP addresses using IPv6 entirely A critical step along the path to IPv6 was implemented on 4 February 2008, when ICANN (Internet Corporation for Assigned Names and Numbers) assigned IPv6 addresses and provided IPv6 connectivity to six of the Internet’s root domain name servers (DNS). Similar enhancements are being made to other top-level DNS (e. g. for . com and . org). The APNIC servers for the . u domain also have IPv6 connectivity. These enhancements to DNS will allow IPv6 devices to resolve Internet domain names into IP addresses entirely using IPv6. Service Providers To connect to the global IPv6 Internet, customers will need to use a service provider that supports IPv6 and provides the require d connectivity through to the global IPv6 backbones. 10 INDUSTRY READINESS FOR IP v 6 Enterprise Virtual Private Networks (VPN) Service providers in the US have begun offering dual-stack VPN services largely to support federal agencies in response to US Government mandates.Telstra’s dualstack IPv6 VPN product capabilities are in an advanced stage of development. Broadband There are still few consumer broadband IPv6 offerings from ISPs, but it is expected there will be an increasing number in the Australian market during 2011-12. Customer Environment In general, few modem gateways and other consumer on-premise equipment currently support IPv6 Consumer Modems and IP Devices In general, very few modem gateways and other CPE appliances in use by consumers currently support IPv6. The main exception includes some high-end PDA mobile phones running Windows Mobile, and some CPE made for specific markets such as Japan.In the vast majority of cases, these IPv4-only devices will not be economically upgradeable to support IPv6. This is because the device is not upgradeable in any way, or because additional resources (e. g. flash memory or RAM) are required to support IPv6. IPv6 capability from many consumer gateway vendors is only starting to be released during 2011. The long lifespan of broadband modem gateways means that many consumers will not have IPv6 connectivity capability for several years unless they opt to replace their modem with a dual-stack capable gateway. Mobile HandsetsDual-stack IPv4/IPV6 capability is expected to become available on selected new mobile handsets during 2011/12. Carriers will need to support IPv6 in their networks for handset use of IPv6 to be possible. Operating Systems Most, if not all, mainstream consumer and business operating systems available now have IPv6/IPv4 dual stack capability. However, legacy systems with either no or limited IPv6 capability (such as Windows XP) are expected to be in widespread use for several years yet . 11 INDUSTRY READINESS FOR IP v 6 Applications and Content ApplicationsMany applications will work when used with IPv6. Others will need to be checked and modified Applications have to be specifically written to take advantage of IPv4/IPv6 dual stack capabilities in the underlying operating system. In many cases, applications will work correctly when used over an IPv6 network. Others will need to be checked and modified to meet the dual-stack requirements and take advantage of IPv4/IPv6 dualstack capabilities built in to most recent underlying operating systems. Applications can be divided into the following major categories: ?S erver applications: Servers typically include web servers, database s ervers and mail servers, but can also include others such as those used for multiplayer online gaming. The applications running on these servers respond to requests from client applications which are carried across I P networks ? C lient applications: End users run client applications whi ch initiate requests to server applications across IP networks (the web browser being the most common example) ? Peer-to-peer applications: In this case the end user application acts as both a c lient and a server and can communicate directly with other users across I P networks.Most applications interface at the IP socket layer and won’t be affected whether the transport is IPv4 or IPv6. However, some applications may have been originally written in a way that ties them to IPv4, and these will have to be modified. Some examples include: ? Use of hard coded IPv4 addresses ? IP address data structures that only cater for IPv4 size addresses ? U ser interfaces that display an IP address, or allow an IP address to be e ntered only in IPv4 format. Many applications, including web browsers, already support dual-stack function. Others are subject to the planned timing of upgrades by the application developer.Ideally, applications should be agnostic to the use of IPv4 or IPv6. An ap plication that supports dual-stack will usually give preference to IPv6 if it is available, otherwise it will fall back to using IPv4. Content Providers Most major Internet content providers have yet to move to a dual-stack architecture Most major Internet content providers are yet to make the move to a dual-stack architecture. Some have established specific IPv6-only versions of their site to enable IPv6 access to users who have IPv6 connectivity, and who deliberately choose to use IPv6 (e. . ipv6. google. com and www. v6. facebook. com). Many Internet content providers are beginning to plan for a dual-stack architecture. This was exhibited when many content providers participated in World IPv6 Day (held on 8 June 2011) to trial IPv6 at a global level. 12 W HAT DOES THE TRANSITION MEAN FOR BUSINESS? Multinational enterprises and those that deal with government departments are most likely to be impacted by government mandates. This will drive the need to support IPv6 (e. g. Australi an Government departments implementing IPv6 in 2012).The IPv4 public address run-out will mostly affect businesses in their external connections Public IPv4 address shortages will have minimal impact on Enterprise VPNs due to the prevailing use of private IPv4 addressing. The IPv4 public address run-out will mostly affect businesses in their external connections to consumers and the broader Internet. Each business needs to consider whether to deliver IPv6 based services to consumers who prefer to use IPv6. Businesses must ensure an IPv6 communication path from the enterprise edge to where IPv6 supported applications are hostedConsumers will move to dual-stack CPE configured with an IPv6 address as well as an IPv4 address (either public or private) in order to access both IPv4 and IPv6 content. Businesses that host applications accessible via the Internet will need to cater for consumers with IPv4 or IPv6 public addresses. Since each protocol needs to work endto-end, for businesses t he transition does not end with deployment of dual-stack devices at the enterprise edge. It also requires enterprise network design changes to make the communication path IPv6-capable from the enterprise edge to where IPv6 supported applications are hosted.Businesses face a similar challenge to service providers, such as Telstra, in making the IP addressing transition. Transitioning to IPv6 requires the full ecosystem to move (i. e. network equipment, modems, consumer devices, operating systems, applications, content servers, IT systems, etc). Therefore, the transition from IPv4 to IPv6 will be a large and complex task that will require significant coordination across the full spectrum of players involved in end-to-end IP services. 13 WHAT IS TELSTRA’S APPROACH TO THE TRANSITION? Telstra has been planning for this transition for a number of years.We have a defined transition strategy and a well-advanced IPv6 implementation program. Telstra has prepared for the transition thro ugh a clear strategy and implementation program Our strategy for IPv6 introduction is based on the dual-stack approach, allowing both IPv4 and IPv6 addresses to co-exist until the transition to IPv6 is complete. This approach will make sure that the transition occurs with minimal impact on customers – they are not forced to move to IPv6 overnight and can deploy and migrate to IPv6 as they become ready.Telstra is already testing a number of key networks and products to seamlessly introduce IPv6 across our services. Timing for implementation in each product will depend on business drivers and equipment availability (e. g. CPE). It covers services across Telstra Internet Direct (TID), Enterprise networks, Consumer Broadband, Mobiles and Telstra’s global networks.

Continued service availability even as IPv4 addresses run out ? Smooth transition to IPv6 at own pace N ative IPv6 connectivity which provides better performance than IPv6 t unnels ? Essentially unlimited Internet addressing ? Leverages the Telstra Next IP ® network. 14 WHAT IS TELSTRA’S APPROACH TO THE TRANSITION? BigPond Broadband Most consumer broadband customers will be more interested in the content and applications they use, rather than which IP addressing protocol is being used. Nevertheless: ? For many, the trans ition to IPv6 will occur smoothly and transparently as e ach of the components of the end-to-end service moves to dual-stack ( e. g. odems, PCs, content) ? T he industry is expecting that Internet content and applications will be d ual-stack or IPv4-only for a long time to come ? I t is unlikely that any significant content on the Internet will be available t hrough IPv6-only for many years yet. Mobiles including Telstra Mobile Broadband ? I nitial availability of IPv6-capable mobile devices is not expected u ntil 2011/12 ? I n the future there may be developments in self-contained mobile solutions, w hich will also drive IPv6 use (e. g. Telemetry and machine-to-machine s olutions).Applications and Content Telstra applications and content will transition to be offered over IPv6 (to achieve end-to-end IPv6) as well as IPv4. Telstra’s Global Networks Telstra’s global networks operated by Telstra International Group adopted the same business approach as Telstra’s g uideline for the IPv4 to IPv6 transition. Key features include: ? D ual-stack approach to seamlessly support the co-existence of IPv4 and I Pv6 IP routing on global IP networks, including the MPLS-VPN platform and G lobal Internet / IP Transit platform N o hard cut-over for customers and continuing support for customer IPv4 a ddress-based IP routing on Telstra global networks in the coming years ? C ontinue IPv4 and IPv6 support for IP network’s auxiliary services such as D NS services on global Internet platform, looking glass on online port etc ? F rom FY 2011/12, Telstra International Group will start leasing IPv6 addresses to customers needing to connect to Telstra’s global IP networks, with limited I Pv4 Address also available ? Native IPv6 Address IP routing on core network is on the road map ?Telstra is committed to work with global network partners for native I Pv6 traffic peering and/or interconnection for both private and public I P networks. 15 WHAT SHOULD B USINESSES DO NOW? Businesses can begin to prepare for their own IP addressing transition through the following steps: 1. Conduct an IPv6 readiness assessment ? Network hardware ? Servers, PCs (e. g. operating systems) ? Network management and security ? Applications ? IT systems ? Organisational capability (IPv6 skills) ? Understand coexistence implications (performance, resources). 2. Prepare an IP addressing strategy Develop a high-level view of transition approach for the business. 3. Develop an end-to-end program view ? Network, IT, devices, applications, etc ? Processes to minimise impacts ? Communication of the IPv6 strategy within the business ? Maintain network security through the transition to IPv6 ? Work with vendors, system integrators and service providers to define d etail and align timings (e. g. link hardware upgrades to lifecycle p rocesses to minimise costs) ? Analyse transition costs and develop a transition budget. 4. Formulate an Implementation Plan ? Identify d ependencies and major milestones Use phased approach based on priorities and timings. 5. Progress Implementation ? Work in close coordination and consultation with network provider ? Telstra commits to providing timely information and updates on its program o f work to assist customers, suppliers and others in the industry to manage t heir transition. 16 WHAT SHOULD BUSINESSES DO NOW? Leverage our Experience and Best Practice Telstra can assist and support customers in their transition to IPv6 through our Professional Services and Consulting Services. The services we provide include: ? Consulting: Planning consultation, including business level investigation and analysis – Conduct a Communications Strategy plan update – Readiness assessments and check lists – Total ecosystem roadmap development (Not necessarily Telstra specific) – Vendor management and CPE – VoIP / other providers / web sites, etc ? Design and Architecture: – Network design – CPE programming remote or onsite (future) ? Project Management: – Transition planning – Seamless transition – Staged transition planning process, achieved via: – Workshops – Customised design – Implementation planning Telstra can provide overall project management to guide a customer t hrough the transition process. 17 CONCLUSION The transition from IPv4 to IPv6 is a known issue which the industry will have to manage over the coming years. The transition will take time as it will require IPv6 to be supported by an end-to-end industry ecosystem including CPE, modems/home gateways, networks, systems (OSS/BSS, tools), content and applications. Telstra has been planning for this transition for a number of years. We have a defined transition strategy and a well-advanced IPv6 implementation program.Our strategy for IPv6 introduction is based on the dual-stack approach, allowing both IPv4 and IPv6 addresses to co-exist until the transition to IPv6 is complete. This approach will make sure that the transition occurs with minimal impact on customers – customers are not forced to move to IPv6 overnight and can deploy and migrate to IPv6 as they become ready. Telstra is already testing a number of key networks and products to seamlessly introduce IPv6. Businesses face a similar challenge to service providers in undertaking a complex transition of their IP ecosystem without impacting services.It is advisable that businesses start preparing their IPv4 to IPv6 transition strategies. Telstra will provide timely information and updates on our program of work to assist customers, suppliers and others in the industry to manage their transition. 18 APPENDIX 1 – IP ADDRESSING IP Address Header Formats Table1 0 16 Ver HL TOS Total Length Identification TTL 32 Flag Protocol Fragmet Offset Header Checksum Source Address Destination Address Options Padding IPv4 Header 0 16 Ver 32 Traf. Class Flow Label Payload Length Nx t Hdr Hop Limit Source Address Destination AddressIPv6 Header Address Ranges Both IPv6 and IPv4 address ranges are often referred to in CIDR (Classless InterDomain Routing) notation, indicating how many of the bits in the range are used to identify the network prefix while the remaining bits identify subnets and hosts. For example, in 62. 0. 0. 0/8 or (62/8), the ‘/8’ indicates that the first 8 bits in the range are used for the common prefix and the remaining 24 bits are used for the host address within that network. 19 APPENDIX 1 – IP ADDRESSING Individual Addresses and Notation Table2 Address FamilyWritten as Example IPv4 Dotted Decimal Notation 144. 135. 19. 10 (four decimal ranges written to represent each byte of address space) IPv6 Hexadecimal notation (eight hexadecimal ranges written to represent two bytes, separated by colons) IPv6 (short-hand) Hexadecimal notation 2001:0db8:85a3:0000:0000: 8a2e:0370:7334 2001:0db8:85a3::8a2e:0370:7334 (eight hexadecima l ranges with zeros removed) Private Addressing In IPv4, four specific address ranges were allocated for use in private networks (e. g. within an enterprise or home). The ranges are: ? 10. 0. 0. /8 — quite often used by large enterprise networks or internally by ISPs ? 172. 16. 0. 0/12 — often used to number enterprise or ISP backbone networks ? 192. 168. 0. 0/16 — often used in small office/home office (SOHO) applications ? 169. 254. 0. 0/24 — used for link-local applications. These private addresses have no meaning on the public Internet. If external connectivity is required by nodes addressed privately, Network Address Translation (NAT) is used to translate the first three of these address ranges into public addresses when accessing the broader Internet.IPv6 also has a range of addresses identified for local use known as the Unique Local Address range FC00::/7 (defined by RFC4193). In IPv4, when an interface is assigned a link-local address, we assume that the device is only connected to a local network. However, the practice of assigning multiple identifiers to interfaces is expected in IPv6 and therefore, all interfaces maintain a link-local address and additional IPv6 addresses. Table 3: Unique Local Address Range 0 78 FC00::/7 1 48 Global ID 64 Site Subnets Interface Identifier With regard to NAT, industry IPv6 addressing practices are still developing.Although there is a hope that significant use of IPv6 to IPv6 network address translation will be avoided, it is not yet clear as to whether enterprises will use public IPv6 space (derived from a registry), provider IPv6 space (granted from an ISP), or a local addressing scheme together with IPv6 NAT. 20 REFERENCES I The remaining allocations by the Asia-Pacific Network Information Centre are now rationed to a maximum of 1024 addresses per member under their latest policies – see â€Å"Policies for IPv4 address space management in the Asia Pacific region†, http:// www. apnic. et/policy/add-manage-policy.

Narrative Essay — The Birth of my Daugher

It was day like any other day, one that revolved around me and my wants and needs, but all that was about to change. The sun was shining through my bedroom window of the small two bedroom apartment that was shared between me and my roommate. The day was a nice enough day for all to enjoy. With temperatures in the 80's and not a cloud in the beautiful Carolina blue sky, who wouldn't want to enjoy a day like that? Not me. Not when I was nine months pregnant, with only seven days till doom's day and whale (yep, spelled it that way on purpose) past the 25-35 pounds suggest by my doctor that I should gain.I was sick from not being able to stomach even the thought of food, which was unusual for me and was starting to have some pains in my abdomen but had brushed it off, thinking it was due to the nausea. It didn't take long to realize that the baby I was carrying was ready to meet me when the back pains started to become regular and more intense. As I laid on the beautifully crafted gold a nd burgundy comforter that was spread over my bed, I started to fell pressure in my lower back. It was as if someone was taking dull knives and running them deep in to my muscles along the top of my tailbone.There was no doubting the fact that my labor had started when I got up and noticed that same elegant comforter was now forever stained. My water had broke causing the pains to bring me to my knees. With tears in my eyes, I was ready for some relief from the pain and wanted to get to the hospital in order to get an epideral(wonderful things that make you numb from the waist down). It didn't take long to get to the hospital, especially since the ride was in an ambulance. Thanks to my roommate who dialed 911 in a moment of panic; hers' not mine, she deemed it necessary to dail 911 and request assistance.If that is what you would call a request, screaming at the top of your lungs at the 911 dispatcher. The pain had become unbearable and I was forever thankful when I was told by the mid-wife that it was time to start pushing the baby out. Two minutes later at 12:37pm on a bright Tuesday afternoon, my daughter was born. She seemed so small and fragile but the effect was immeasurable. Lynssa Grace Girma Adugna, 6lbs. 5oz. 20 1/5in. Her hair was so shiny that it looked brown with touches of gold thrown in here and there. Her eyes were such a deep, dark blue that they look like the ocean at night.She was breathtaking. When our eyes met for the first time I felt my heart skip a beat. As I held that tiny bundle, that was just as much a part of me as I was a part of her, my mind was in awe of how much I immediately felt such an overwhelming amount of love for her. The kind of love that I felt in that moment was instant and was more intense then any emotion I had every felt. I never knew that this kind of love was possible, to be able to love something or someone the way that I loved her. I knew then that I would go to any lengths to make her happy and to give her ever ything that she every needed.I swore to give her my absolute best and I meant every word. My entire existence had been meaningless up until then, or at least everything I had every accomplished felt like it failed in comparison to her, my daughter. I had never knew that there was an emptiness in my heart until this completeness replaced where there once was a void. When my daughter came home the â€Å"real world† begun. I traded nights with the girls for a night with the most important girl, and nights out with friends, to midnight feedings and diaper changes. These times were stressful without a doubt.Although all I needed to make them worth the work was a glimpse of her smile. Which she would give while she was sleeping. I am told that babies are dreaming about angels when they smile like that. These late nights were hard to handle when they were followed with early morning wake up calls which gave way to a morning full of much needed errands. My life was no longer my own. Life now circled around this tiny little human which I was trusted to take care of . Before Lynssa came along, I was not the one who you could find in a church pew on Sunday. You did good to see me on the holidays such as Christmas and Easter for that matter.Now that I was responsible for someone else's mortal soul, it seemed very important to get back in church and to teach her the same values that were instilled in me. So now you can be sure where to find me on Sunday. I wanted to be sure to incorporate Christian values and beliefs into my child's heart and mind, and the only way to do that was to but them back into mine. Even though my child is very young and not likely to remember these times, somehow I still believe that it is important to behave a certain way. I also changed not only my outlook on life but also my outward appearance as well.I begin thinking in ways that would have never come to mind before had my daughter never been born into this world. There was not only the fact that I was a mother now that changed me but also the fact that I was the mother of an impressionable young girl was what affected me in a way that I never though possible. I wanted her to be everything that was good and right about me and none of what was wrong with me. I decided that the best way to teach her these things was to lead by example, and with a little hope and a lot a prayers she would follow. I needed to be the mother that my child could be proud of.Nobody's perfect and I sure do have a long way to go before I can even be close to being where I want to be in life. I am still learning. Learning new things everyday. Changing for the better a little everyday is my goal. To always be that person, striving to be the best mom, wife, daughter, sister, friend and student that I can possibly be. That's who I am. I would never be the person that I am today if I had not received an award so great as that of motherhood. Word do not express how thankful I am everyday when I s ee my daughter is growing and becoming a little lady.

A middle class family named The Birlings Essay

An Inspector Calls, written by J. B. Priestley, is about a middle class family named The Birlings. The Birlings lived in an up and growing industrial town in the north midlands. Set in 1912, the Birlings were happily celebrating their daughter Sheila’s engagement to a respectable businessman, Gerald Croft. However, the modest celebration turned out to be more than eventful when an unexpected inspector arrives enquiring the suicide and death of a young girl names Eva Smith. Whilst doing so, the inspector unlocks a chain of family secrets along the way. The play, in its time, proved to be very popular, and still does so today. In this play, I think that J. B. Priestley chose the characters very well. I think that what made the play so appealing is the way in which he gave each character such a strong personality. Each member of the Birling family has a unique personality and throughout the play some of the Birling family change. I do think however, that the Birlings as a whole family are quite stereotypical. The Birlings come across as a family that have wealth and seem to be quite a respected family of a high class. At the beginning of the play, the Birling family seem to be quite a closely bonded family but throughout the play this bond seems to drift apart as they recognise their differences. The family consists of four very unique and exciting individuals: Arthur Birling- A very self-obsessed, wealthy business man, also very self-opinionated. The perfect example of an old snob. Obviously very proud of his achievements in life, but with his heart set on a knighthood which would be his ultimate achievement. Sybil Birling- Considers herself high in regard to social standings, largely on the back of her husbands’ success and wealth. Possibly a ‘Hyacinth Bucket’ of her time. A very unlikeable woman who sees lots of people as being beneath her. Sheila Birling- comes across as a very polite and obedient woman, looking forward to her engagement to Gerald Croft. However, as the play goes on, Sheila begins to realise the truth about herself and the Birling family, and begins to stand up against them. Eric Birling-Quite an enclosed person. Eric’s personality is hard to detect. He seems to be the outcast of the family, and the family do not discover until later on in the play that Eric is in fact a heavy drinker and was to father a illegitimate child. A typical wealthy young man of the day.

My hobby (listening music) Essay

What is music? Music is the art or science of combining vocal or instrumental sounds (sometimes both) to produce beauty of form, harmony, and expression of emotion. As a teenager, I listen to music everyday. I can name almost name every song that comes on the radio. Listening to music takes the stress away from my mind. I love listening to music. Listening to music is my new hobby. I cannot go a day without listening to music. Music comes in different genres. I listen to many genres. The genre I listen to the most is R&B. I listen to R&B because it relates to my life. R&B is one of the tops ten genres listened to. Music to me is like a reading teacher reading a book. Music is just that good. The R&B singers I listen to are Keri Hilson, Trey Songz, Monica, K Michelle, and Usher. I listening to more than that but I do not want to waste my time writing all of the names. I wake up listening to music. Music is my passion. While I am writing this, I am listening to music. I cannot help myself. Some people are addicted to drugs and alcohol but my addiction is music. Music has many different meaning to it. In order for me to understand a song, I have to listen to the song over and over again. If someone gave me a pop quiz on music, I would most likely pass the pop quiz. I am not the type that does not have a life. I have a life, but in the meantime I listen to music when I am bored. I might listen to a great amount of music but I do not know how to do have of the dances that go along with them. Again, music is my passion and addiction. One more thought, I cannot sing. I just love listening to music.
