Development Of Standardized Ipv6
Abroad IPv6 Standardization process In the formulation of standard international organizations IPv6
, IPv6 protocol mainly by the I? ETF development, IT U IPv6 protocol is considered Telecommunications Networks; 3GPP organization responsible for IPv6 in 3G core network and the application of 3G terminals.
IPv6 protocol in the IETF process is largely complete within the organization.
Current IETF standards for IPv6 working group developed two main: IPv6 Working Group (IPv6) and IPv6 operations working group (v6ops), belonging to transmission areas and areas of operation and maintenance.
1. IPv6 Working Group IPv6 for the formulation of norms and standards, its predecessor is the IPng working group. The group's responsibilities is to continue the development of IPv6-related technical standards, and second, implementation and deployment of the situation under review and update the IPv6 standards and norms. The working group will now be divided into these two categories are "urgent deployment" and "complete the current work", in which the former category is the IPv6 working group is currently working to be a priority. The working group has finalized a 65 RFC (RFC addition of 17 has been abolished for various reasons).
IPv6 working group draft is currently being studied are: IC MPv6 norms; default Router As well as more specific routing options; for IPv6 router host load sharing; this link IPv6 multicast address; IPv6 node requirements; IP Forwarding Table MIB; IPMIB; UDPMIB; unique local IPv6 unicast address; IPv6 addressing framework; IPv6 Tunnel MIB; IPv6 stateless address auto allocation; optional IPv6 duplicate address discovery; uniform distribution of unique local IPv6 unicast address; IPv6 Neighbor Discovery; IPv6 stateless address allocation, private extension; IPv6 router announcement and M O sign of consideration; similar to the bridge of the neighbor discovery proxy.
2. v6ops Working Group Responsible for the evolution of mechanisms, tools, and deployment of standardized work, its predecessor is NGTRANS Working Group. 2002, IETF disbanded the NG? TRANS working group set up a new IPv6Operations (v6ops) working group, the working group is currently the main responsibilities of the following areas.
(1) according to operators and users from the requirements and recommendations of IPv4/IPv6Internet in operations or security problems, identify solutions to these problems or scenarios.
(2) to the IPv6 Working Group on the IPv6 specification to cause or may cause operational or safety problem areas, together with the IPv6 working group to address these issues.
(3) released some information of the RFC, guide the application developers to develop applications with the IP protocol and operational independence, that is developed for both applications in the IPv4 and IPv6.
(4) release of some information or BCP (BestCurrentPrac? Tice) type of RFC, in the public network to identify and analyze the design of IPv6 environment.
(5) clear the deployment of IPv6 in the environment faced by the opening of the operation or safety issues, filed for the RFC or ID.
(6) take on the evolution / transition mechanism to promote the work. Apart from the above, some important work is closely related to IPv6 IETF is also underway to promote the IETF in the identification and development of appropriate solutions for the standardization process.
V6ops working group is studying the draft: 3GPP network to IPv6 transition analysis; IPv6 hosts and routers, the basic transition mechanism; IPv6 enterprise network scenarios; no time limit on the IPv6 Renumbering process; IPv6 Enterprise Network Analysis ; the NAT-PT conversion experiments (Experimen? tal) state the reasons; operators in broadband access networks, IPv6 development scenarios; IPv6 network protection.
IPv6 standard system in China Although due to a late start in China in the information area, there are few international standards of our submission, but standardization is still very important in our country. IPv6 standard system contains a lot of content. China's two important aspects of the standardization of the interface and protocol standards and their Test And equipment standards and testing. Standard interfaces and protocols is mainly localized to the international standards. Course may be based on international standards with Chinese characteristics, a number of options to choose. Equipment and testing standards for major network equipment for network testing. The operators work in an internal working abroad, but at home as long Separation of the telecommunications industry, equipment specifications and testing has become an important part of industry control. Current corresponding test equipment and test the protection of public telecom networks and quality of basic services and gateway interoperability is still important, it is still necessary to develop equipment standards and equipment test. The future trend of telecommunications industry standards for interoperability and carrier network interconnection network quality of service and so on. Equipment performance functional requirements should be left to operators to decide.
Although the commercialization of the industry on IPv6, the time differences still exist, but to eventually replace IPv4 and IPv6 in Communicate Networks play an increasing role has become common. China as an Internet and communications technologies and markets in rapidly developing countries, urgent work in the standardization of IPv6. In the standard setting, not only should meet international standards, and should participate in international standard-setting. If the broad participation of various industry standards development, manufacturing and rapid follow-up network operators to provide timely and appropriate services, China is entirely possible upper hand in the development of next-generation Internet.
