Address shortages push IPV6 to accelerate development

China Electronic newspaper Liu the rapid growth of Internet users in China makes the IPV4 address resource shortage more scarce, and broadband network, mobile internet and hot talk of the networking, all need to have sufficient IP address resources to do business development support,　　In the domestic mention of nearly 10 years of IPv6 finally ushered in a real opportunity for development. Two operators actively promote the smooth transition of the network and promote the cost of transformation. Zhang Feng, director of the Communications Development Division of the Ministry of Industry and Information technology, said in a recent meeting of the 2010 global IPV6 Next-generation Internet Summit: "The development of the next generation Internet is a complex system engineering, Not only need the government departments to strengthen the overall planning, policy guidance and promote international cooperation, but also need chips, software, terminals, equipment, networks, applications, security and other industrial chain links in close cooperation and coordinated progress.　　As the leading enterprise of the industrial chain, the operators ' planning of IPV6 affects the whole industrial chain. China Telecom announced its overall deployment to the IPV6, from 2010 to 2011 for the trial commercial stage, the launch of the Network Peace Station IPV6 transformation, small-scale commercial; 2012 to 2015 to achieve scale of commercial, business gradual migration; The proportion of IPV6 after 2015 has gradually increased,　　New applications dominate. According to Chen Yunqing, deputy director of the Network Business Research Department of China Telecom Beijing Institute, China Telecom facing the Internet from IPv4 to IPv6 migration of this huge project, focusing on four lines: first, to ensure the smooth transition of the network to ensure the security of the network; the second is to promote the continuous reduction of the cost of transformation, phased and phased implementation of the transformation　　Third, to promote some important technologies, including the inheritance of the IPV4 network and its application in the process of the introduction of the IPV6 network of the exchange of services, the terminal and the corresponding application of the transformation of the network supporting the upgrade and so on, four is in line with the Government to promote business development. China Mobile is also pushing ahead with its IPv6 process. Chaixiaodong, deputy Director of Network Technology Institute of China Mobile Research Institute, said: "Last year we did some experiments on IPv6, first, we carried out two large-scale testing, testing the support capacity of the network and the end-to-end capacity of the mobile networks; the second is to develop business based on IPV6, such as MMS, WAP and so on have realized the Ipv6ready, also did the ultra high Definition IPV6 video communication, third is impels the mobile terminal to support the IPV6. "Pilot will accelerate the industrial chain of mature Hunan pilot results terminal support weak Chen Yunqing said:" The lack of address has become a good driving force for development IPv6, we in the 2008, 2009 in the two years, with IPv6 related to some of the modified test and application practices, including the development of enterprise-related equipment, Business, technical testing specifications. In 2010 we began to prepare for the pilot of the current network, and to build and operate the network supporting IPV6 business in the Shanghai Expo Park. "The pilot that has seen the effect is ChinaHunan pilot of telecommunications, one of the pilot in its Ipv4/ipv6 dual protocol stack Network, the first implementation of the End-to-end IPV6 business support ——— the user side with the support of IPV6 dial-up software, access to the server can identify the software, so that its IP address into China Telecom's AAA system to do certification, At the same time, the CRM system has been reformed correspondingly; second, China Telecom has obtained the authentication of IPV6 forum ipv6enabled for the first time, the third is based on this, China Telecom deployed a IPV6 application system for the first time ——— Hunan Agriculture Integrated Monitoring system. At this conference, IPV6 Global Forum President Latifladid to China Telecom officially issued the world's first IPV6ISP service operator certification.　　At present, China Telecom has completed the transition from IPV4 to IPV6 Technical Research, program development, equipment, terminal testing and other work, selected Changsha, Wuxi, Guangzhou, Chengdu and Jinan 5 cities to carry out IPV6 pilot work.　　Latifladid to the "China Electronic newspaper" reporter said, in order to promote IPV6 industry capacity, following Ipv6ready certification, 2009 launched a ipv6enabled certification, from equipment certification to the ability to authenticate. Chaixiaodong said: "Through testing and business experiments, we found that the support of IPV6 equipment distance to achieve commercial still gap, in the key router equipment is not mature enough, the industry will need to do a lot of work." "In addition to network equipment, IPV6 lack of application has become a constraint on the industry another bottleneck, in the eyes of China Mobile, supporting the application of terminal equipment must first have the ability to support IPV6." "With the start of the 3G, the market ushered in a terminal equipment replacement period, should be in the mobile phone network detection when the mandatory terminal has the ability to support IPV6." "Chaixiaodong said.　　Referring to China Mobile's TD terminal, he said, the current support IPV6 TD mobile phone has not yet launched, only a chip companies have a clear IPV6 support program, TD mobile phone support for the IPV6 is still relatively weak. A variety of network migration routes to be selected network migration challenges the whole system different operator schemes "IPV4 Network transition to IPV6 network is a system engineering, from the support system to the business system to the terminal is End-to-end system transition, which is a challenge to the entire system."　　"ZTE Carrying network enterprise network and radio and television market director Cao Lixin in the" China Electronic News reporter interview, said. At present, the industry has proposed a variety of network migration technologies, including: Double stack technology, tunneling technology, NAT technology, as well as emerging ds-lite technology. "We will track a variety of technologies, but only one or two of them will be selected in the end." "At present we are promoting the progress and improvement of the double stack technology," Chen Yunqing said. "Shanghai Bell Company strategy manager Chen Duan said:" IPv6 introduced, the network will have three kinds of address, namely IPV4 public network address, IPV4 privateNetwork address and IPV6 address, IPV4 public network address after 12 months may not have an assigned address, and from the IPv4 to IPv6 migration is not so fast, so support IPV4 private network address of the NAT technology introduced is unavoidable.　　While the French telecom adopted the Ds-lite (Dualstacklite) technology in the implementation of IPV6, the technology applied in the later stage of the network transition and IPV6 dominant period was taken seriously by the industry. "There is no solution to all the scenarios that the network is evolving into IPV6." There are different scenarios for different operators and different scenarios.　　"said Liu Shaowei, vice president of the IP product line of Huawei operator. Internet of Things becomes IPv6 new power IPv6 can support IoT node communication micro-environment need IPV6 simplify protocol stack "from now to the 2020 10 years, China's Internet of things will experience the application of innovation, technology innovation, service innovation, 3 key stages of development, Grow into a huge industry of more than 5 trillion yuan scale.　　Zhongguancun IoT Industry Alliance, the Great Wall Strategic advisory joint release of the "Internet of Things Industry Development Research (2010)" depicts such a piece of China's Internet industry development prospects.　　The study argues that the next generation of Internet IPV6 Technology, which provides a large number of node addresses, provides a possibility for a wide range of IoT applications to be transmitted by a more convenient, reliable, and secure way to transfer nodes to a central node or to an information processing unit. According to the China Telecom Technology Department of senior Steering Feng introduced, Hunan China Telecom Pilot is the first IPV6 based on Internet applications.　　The main functions are: Video viewing plant growth situation, real-time collection of indoor and outdoor temperature and humidity, light, CO2 concentration, irrigation water and other key data, remote control skylight, edge windows, shading nets and other external implementation equipment. China Mobile has made more specific suggestions on how to use the IPV6 development Internet. Chaixiaodong said that China's mobile machine-to-machine business has developed for a long time, with more than 4 million users, and is also studying how to introduce IPv6 into the internet of things. The problem is that a lot of IPV6 protocol message is relatively long, power consumption will be relatively large, and the node of the internet of Things is low-power, two batteries should be able to use half a year, in this micro-environment using IPV6, you need to make a simplified protocol stack.
