It was learned in the "China next generation Internet business promotion conference" that the penetration rate of IPv6 in the United States, France, Romania, Japan and other countries has exceeded 2%; there are five top 10 international ICP (Google, Facebook, youtube, Yahoo, Wikipedia) that have fully supported IPv6, while China's penetration rate of IPv6 is only 0.48%, unable to rank among the top in the world.
At the same time, IPv6 commercial deployment in China still faces many challenges. According to the expert committee of China's next generation Internet demonstration project (CNGI), at present, IPv6 commercial network coverage and user visits in China are very low, with a coverage rate of 14.83% and a utilization rate of only 0.07%; commercial websites and application providers have not yet found a commercial profit model for IPv6 business, lacking the core driving force for active transition to IPv6; The overall level of IPv6 industry chain needs to be improved, and the supporting capacity of industry chain needs to be strengthened; there are short boards in the core and basic software, and the development of IPv6 mobile terminal lags behind.
Based on this, Zhao Huiling, chief engineer of China Telecom Beijing Research Institute, thinks: 'the difficulty at this stage is that the workload of network transformation is large, the bottleneck of the terminal is difficult to break, and the development of the user depends on the maturity of the terminal. However, the replacement cost of the user terminal is high, the transformation is difficult and the cycle is long. "She suggested that IPv6 should be clearly required in the network access test of domestic mobile terminals.
'content and application are the key to attract users and drive IPv6 traffic, but IPv6 business is still lacking. At the same time, the industrial chain needs close cooperation, and foreign development experience also shows that industrial cooperation can greatly reduce the risk of network and business upgrading, and promote the effective development of IPv6. 'said Zhao Huiling.
In response, Wei Chenguang, vice president of China Mobile Technology Department, also said that mobile terminals are one of the key links to successfully realize IPv6 deployment. China Mobile is working with many manufacturers to accelerate the maturity of IPv6 terminal chips and promote the mass production of IPv6 mobile terminals.
Although IPv6 commercial deployment in China is faced with various problems, the three major operators are actively promoting the upgrading of commercial networks to IPv6.
'China Telecom's plan is to implement the current network commercial pilot in 2012-2013, promote IPv6 technology development and network coverage, and complete the support system of key provinces in the Middle East and the upgrading and transformation of some metropolitan area networks in the province; In 2014-2015, a comprehensive commercial deployment was implemented, focusing on the promotion of IPv6 scale development, and the upgrading and transformation of supporting systems in all provinces of the country were completed. Besides some metropolitan area networks in the West and North, IPv6 coverage was basically achieved. "Said Zhao Huiling, chief engineer of China Telecom Beijing Research Institute.
In terms of IPv6 service provision, China Telecom's fixed network broadband access is currently open to some regions in Jiangsu and Hunan, and more than 20 key cities such as Beijing, Shanghai and Guangzhou will be opened by the end of this year; mobile broadband access is open to 5 cities including Beijing, Shanghai, Guangzhou, Nanjing and Chengdu; At present, IDC services are open to six IDC's in Shanghai, Jiangsu and Zhejiang, and more than 40 IDC's in Beijing, Shanghai, Guangzhou and other major cities by the end of this year; IPv6 VPN services are open to more than 30 cities, including Beijing, Shanghai, Suzhou, Shenzhen, and Shanghai, Guangzhou, by the end of this year.
By the end of May 2013, about 400 bras of relevant man had IPv6 user access capability, and 13 IDC networks in Beijing, Jiangsu, Zhejiang and Shanghai had IPv6 access capability. It is expected that by the end of June, some areas of the demonstration project involving man and IDC room will have IPv6 access capability. 'said Zhao Huiling.
At the same time, China Mobile is also vigorously promoting the maturity of IPv6 industry chain, actively carrying out pilot and trial business, gradually expanding IPv6 users and network scale, and realizing IPv6 Transition of the whole network.
Wei Chenguang, deputy general manager of China Mobile Technology Department, told reporters that the development of IPv6 in China Mobile is divided into three stages: during the start-up period of 2012-2013, scale test is mainly carried out, network transformation in about ten provinces is started, multiple lteipv6 terminals are launched, 4 business bases and more than 10 free business platforms are transformed, and 3 million IPv6 users are developed; The main task of the promotion period 2014-2015 is to upgrade the whole network, strive for the network support of IPv6 in the eastern developed areas and 50% of the underdeveloped areas in the central and western regions, gradually realize all free services support IPv6, and all new mobile and fixed terminals support IPv6; since 2016, realize the comprehensive application of IPv6, and realize that new users can use IPv6, and new terminals, equipment and services fully meet the requirements of IPv6.
IPv6 is not only an opportunity for protocol upgrading and network transformation, but also a chance for new network architecture reform. It is also a good opportunity to promote IPv6 network to achieve peer-to-peer connectivity and create a more flat and high-quality next generation Internet. "Wei Chenguang said.
In terms of IPv6 commercial deployment, China Unicom has adopted the three transition principles of "smooth transition, technological innovation and business driven".
According to Fu Chengpeng, chief scientist of the next generation Internet of China Unicom, "Unicom focuses on stability in the backbone network, and all C nodes open IPv4 and IPv6 dual stacks; a node in the province where the pilot city is located opens dual stacks, such as setting up a separate cngi-s in Beijing as the border router for interconnection with other operators. The transformation of man IPv6 follows the principle from easy to difficult, first core Cr, then bras / Sr, and gradually transition to IPv6. '
The exhaustion of IPv4 brings about the use of IPv6. In a sense, the use of IPv6 also represents the level of Internet development in a country.
