Analysis of IPv6 Standards and Analysis of Development Dynamics in my country
August 13, 2004 Communication World,
(1) The process of international IPv6 standardization
IETF has always been responsible for the development of IPv6 standard main body, and this situation will not change in the future. However, due to the huge impact of IPv6 on next-generation networks and 3G networks, more and more international standardized organizations join the IPv6 standard development. Therefore, in the international standardization organization, in addition to IETF continues to improve the standards related to IPv6, 3GPP and ITU-T have also established corresponding working groups to develop standards related to IPv6. At the same time, IETF and 3GPP have nearented a working group to coordinate the application of IPv6 standard in the third generation communication system. Below is a brief introduction to these organization IPv6 standards.
1, IETF
The development of the IPv6 standard main body is mainly responsible for the IETF. After years of hard work, IETF has been developed more than 100 RFCs related to IPv6 protocols. IETF has two working groups responsible for the development of IPv6 standards: IPNG (next-generation Internet protocol) Working Group and NGTRANS (next-generation network evolution) Working Group.
IPNG (IPv6) Working Group: The IPNG Working Group began working in IPv6 standard in 1992 and officially identified IPv6 fundamentals in 1995. NGTRANS Working Group: There are 4 tasks of the working group: standardize methods and tools for IPv6 evolution; documents related to IPv6 evolution; coordinate 6bone test bed; test address assignment and coordinate IETF and other organization IPv6 activities .
2,3GPP
Developed the 3GPP (Third Generation Partnership Project) of the next-generation mobile communication system "IMT-2000" standard, which has decided to support IPv6 in the basic protocol of next-generation mobile technology in May 2000. The following table is the 3GPP standard for IPv6 support. .
3, ITU-T
ITU-T is an international standards for intergovernmental international standards. In recent years, due to the rapid development of IP technology, traditional telecommunications standards have been greatly affected. Currently, ITU-T and IETF have cooperated in IP standards. ITU-T specializes in the development of an IP standard plan, and IPv6-related standards are listed there.
4, IETF-3GPP IPv6 Design Group
IETF and 3GPP form a working group in 2003 to coordinate the application of IPv6 standard in the third generation communication system. The current work of the Working Group is to review the IPv6 standards in 3G and numbered corresponding standards and deploy work plans in these areas, including IPv6 in 3G standards, addressing methods, and mobile phones Equipment support (router, proxy server), DNS, security, MTU, network evolution, remote management, and mobile IPv6.
(2) China's driving force of China's development IPv6
For China, the development of IPv6 has mainly:
1. Make the future development of the Chinese network to break the scarcity of the address resource
China's IPv4 address is very lacking. The world's most populous countries have only 20 million IP addresses (less than a Class A address). In recent years, the development speed of my country's Internet is a sharp step. The data of "the top 25 countries and regions ranked" in the Internet users "indicate that China's Internet users have grown from 2000 to 2003. The rate is 202.2%, ranking second in the world. At present, China's netizens are 79.5 million, ranking second in the world. In China, the rapid development of network addresses and the rapid development of network size has formed a distinct contrast, and IPv6 uses will be fully able to change this situation.
2, IPv6 will promote the development of my country's information industry
After IPv6 realizes industrialization in China, IPv6 can not only completely solve the problem of address lack, but also bring major opportunities to China in the Internet. For equipment manufacturers, telecom operators, home appliance manufacturers, and even end users, seizing this opportunity will bring their own vibrant changes. IPv6 also paved the way for the Internet and popularity of my country's non-computer terminals in the future, which will bring more convenience to our lives and work. As IPv6 is getting ripe, from mobile wallwrites, from TV to cars, more and more, increasing non-computer information terminals will connect to the Internet, truly we live and work every link, each A component is hooks with the network. At that time, the computer is no longer the main components of the Internet, those non-computer information terminals such as calls, television, mobile phones, and home appliances, such as calls, television, mobile phones, and home appliances will become mainstream.
3. Make China to win the chance of transforming from introduction technology to boot technology development
For China's industry industry, IPv6 will enable China to win a chance to transform from the introduction technology to boot technology. In the mature era of IPv6, the first market that truly need IPv6 is not advanced in Europe and America, which may be our China. Only market demand can drive technology development. If you seize this rare opportunity, China will do the world's latest attempt in this new field, launch the world's latest service, and achieve the world's latest experience and technology accumulation, so that The industry is internationally striving to technical leadership, service leadership, thus gain strategic competitive advantage.
(3) China IPv6 Development Status
1. Government macro guidance and coordination, overall planning and layout
Developing the next generation of Internet is a huge and complex system engineering, to carry out overall planning and layout under the macro guidance and coordination of relevant state departments. Key breakthroughs to restrict the key technologies of my country's next-generation Internet development, actively participate in the development or revision of international standards, and strive to form a large international and domestic market with independent intellectual property products.
Some research institutions, colleges, manufacturers, and operators in my country have begun to track and pay attention to the development of IPv6 technology, and some have even put into research and development power, and they have also completed some IPv6 test beds and experiments. Net, such as 6TNET (Next Generation IP Telecom Experiment Network), Hunan IPv6 Experiment Network, CERNETIPV6 Test Network, Chinese Academy IPv6 Demonstration Network, etc., these networks are only small, experimental of.
China's next-generation Internet Demonstration Project (CNGI project) in 2003 is a national strategic project, based on the Ministry of Information Industry, Ministry of Science and Technology, National Development and Reform Commission, Ministry of Education, Information Technology of the State Council, Chinese Academy of Sciences, Chinese Academy of Engineering and The eight ministries of the National Natural Science Foundation of China jointly launched and launched by the State Council. The main purpose of the project was to build the next-generation Internet test platform, IPv6 is an important technology to be used. In the launch of this project, my country's IPv6 commercialization process entered a substantive development stage. The CNGI project will be divided into two steps.
The first step, the eight ministries organized the bidding of each operator. According to different technical issues, different regions are bored to China Telecom, China Netcom, China Mobile, China Unicom, Tiemong, Science and Technology Network and Education Network and other six units, the bidding work has ended last year in August last year.
In the second step, major operators will be tendered in equipment manufacturers at home and abroad to carry out their own IPv6 network. Before the end of 2005, most provinces and cities in the country will establish IPv6 core backbone network. After 2006, each operator will develop their own characteristics based on their own advantages.
According to the overall plan of the CNGI project, by 2005, under the guidance of the government, China's 5 major operators and academic research network CERNETs will construct 6 national IPv6 backbone networks (covering 39 important nodes in the country) and at least 2 exchanges. Center (IX), test interconnection between individual IPv6 backbone networks. Based on this national IPv6 network platform, major operators will cooperate with major parties to complete IPv6's research topics, and conduct tests, development, major application demonstrations and applications of IPv6 key technologies based on their respective network conditions and business development needs. Extension. The entire CNGI project has a total of about 1.4 billion yuan in 2005, including approximately 600 million yuan for procurement equipment, and other supporting funds for each operator. 2, operators' exploration work
China Telecom, China Netcom, China Mobile, China Unicom, China Tietong and other domestic major operators, in the next generation of Internet and IPv6 tests and commercial aspects, already or is working in active exploration. Most operators have built their own R & D centers and R & D architecture. It has established and continuously improved the corresponding experimental environment for their respective operational characteristics. It has carried out active research in various aspects such as IPv6, IPQoS, MPLS, and transmission technology. Support the research and development foundation for next-generation Internet research tests. These work have been obtained or partially achieved, laying a certain basis for the next generation of Internet construction in my country.
3, the development of domestic standards
At present, China's IPv6 standardization has been launched. The first batch of IPv6 industry standards have basically formulated, including: IPv6 basic protocol, IPv6 network overall requirements, stateless address configuration, mobile IPv6, routing protocol OSPF and BGP4, etc. The batch of China IPv6 standards were developed. China IPv6 standardization work mainly around the following six aspects: basic agreement, network architecture and performance index allocation, network evaluation standards and test methods, network equipment standards, network equipment testing, mobile communication standards, IPv6 business and Application standard.
(4) Analysis of China IPv6 Development Prospects and Strategies
1. Analysis of China IPv6 Development Prospects
The development of China IPv6 in the future will follow the track:
(1) Only a few countries have achieved substantive progress in IPv6, and the global development situation has not been fully opened, and China's comprehensive deployment is very large; and the way to develop self-development in the industry may make China lose a good time. Development opportunities. Therefore, under the joint efforts of the national organization and the industry, build a large-scale experimental network, orderly development, accumulation experience is the best strategy of China's current IPv6 development, CNGi project is the embodiment of this idea;
(2) China's IPv6 will pass the organization and condense of the government, and the entire industrial chain is organically combined, thereby achieving the rapid and orderly development under the government's unified coordination;
(3) CNGI will play a role in the industrial incubator, from building a large-scale IPv6 backbone network to interconnection interconnection between various networks and various characteristic applications on the network will be formed in this incubator and move toward maturity, and travel;
(4) Giving domestic and foreign equipment, especially in unprecedented development opportunities, making domestic manufacturers have the opportunity to stand on the wave of technology development;
(5) With the unified planning, ideology and investment of the country, each operator will no longer be the polite, self-development, and it will have a greater enthusiasm than before, and the development direction and the goal are more clear;
(6) With a national large-scale next-generation network platform, colorful next-generation applications will gradually move from demonstration to commercialization, in China to form a complete, healthy and orderly industrial chain, which promotes China IPv6 further commercial development.
(7) Although in new technologies such as IPv6, China is standing on the same running line with other countries, but finding appropriate development opportunities and development methods. For China's industry, it may be more important catalyst, only the appropriate China's IPv6 development path, China's IPv6 technology can realize the dream of the world lead. 2, China Operators IPv6 Development Strategy
Compared with the developed countries operators' IPv6 development strategies, China's operators develop IPv6 process and strategies will have a big difference. Developed countries have already had a perfect IPv4 infrastructure, and thus IPv6 network deployment considers how to use for new applications. In China, operators have not enough Internet facilities to cover the entire China (especially the western region). The issues facing China's operators are how to build internet, voice and data network infrastructure with lower cost. A new network technology (such as IPv6) will be a good opportunity to build a network.
Of course, the operator can't invest in a large amount of financial resources in the near future, but in order to continue in the future, operators must pay attention to the development of new technologies in real time, take certain measures Reduce risk, including: Take advantage of the use of new technologies (such as IPv6) when building new networks; build a certain scale of experimental network to understand new technologies and accumulate experience; if you purchase new devices, consider whether the device is considered Support IPv6; promoting new applications, especially in large cities with high network penetration rate; consider basic network services through new technologies (such as IPv6), and on this basis Develop a comprehensive innovation business.
