| Analysis: IPv6 status and face difficulties in the development of
State Circle Nov. 19 IDC report: IP address autonomous system number, name and so kept constitute the foundation for the development of Internet resources. IPv4 address of the current location of Internet nodes basic identity, the length of 32bit, its address space the size of about 4.3 billion, currently the public Internet, proprietary enterprise network routing information to forward basis. early 90 century, the industry has been awareness of the shortage of IPv4 address resource constraints into the core issues of development of the Internet. Address depletion can not be directly affected directly (ie not through NAT mode) to connect the public Internet, network operators can not directly access the new user, service providers can not directly access the new server, affecting the development of new business development network. However, no direct impact on households run out of addresses, what IP address for the associated weak account (IP address of the machine to machine communication), which telephone network E.164 number of Internet domain names are different. But should address depletion problem, network operators need to increase the cost of service providers, which will ultimately be passed on consumption, caused by internet access to costs rise. should be run out of IPv4 addresses address depletion problem of IPv4 addresses, there are two basic ideas, aspects of technology management through various means of trying to reduce consumption of IPv4 addresses speed (throttle), on the other hand began with a massive address space of IPv6 technology standardization (open source). Head widely adopted private address, dynamic address assignment, Classless Inter-Domain Routing address subnet mask and other complex technologies, and tightening of the address allocation policy and other policy instruments, the amount of IPv4 address resources to save the polar push IPv4 address space exhaustion point in time. However, the amount of IPv4 addresses the development of complex technology, deterioration of the global Internet to run the development environment to accelerate the network complexity increases, caused by business innovation, deployment, operating costs continue to rise, while giving traceability with new challenges such as security issues. Head 84% IPv4 addresses have been assigned (including the not so) or set aside, keeping the existing address allocation is essentially the same speed, the remaining IPv4 address consumption rate of 200 million per year (annual consumption growth of about 19%), estimated 18 to 24 months are not so exhausted. IPv4 address depletion has become not be avoided, global strategic issues, objectives Xu countries, including IPv6-generation Internet to promote a positive attitude. European Commission announced the end of May 2008 to encourage EU companies,tods shoes outlet, government agencies, individuals make on behalf of the Internet protocol IPv6, to 25% by the end of 2010 enterprises, government agencies target individuals to IPv6 network protocol. Japanese government to develop South Korea plans to start in 2013 began a comprehensive IPv6, IPv6 to become the world's first universal nation. Begin to exert American IPv6, IPv6 address of the United States suddenly in May 2008 from the world's first 11 months jumped to the world's first (U.S. request to all government departments June 30, 2008 must deploy IPv6 related). IPv6 Development Status States on behalf of the study carried out by the Internet, experiment and demonstration projects. If members of the National Natural Science Foundation of the Reform Commission, August 2008, the State-style boot CNGI second phase, focused on solving the business of promoting the generation of the Internet encountered by some by countries, technical standards have been compared head IPv6 mature countries, ranging from formation of a scale IPv6 trial network, network equipment, mature and business should be some progress. However, the overall development of the global IPv6 perspective, the Asia-Pacific Europe should be more, but still play a leading role by developed countries in different areas of the U.S. Internet was broken-family situation. Japan, South Korea, the European Union take the industrialization of IPv6 research and development side, the field for the development of a slight contribution IPv6 State, but the national strategy, industry, research and development and other aspects of Japan and South Korea, the EU still have no gap. Also, with the development of IPv6, India attaches great importance to progress. <DIV class = |
