Ipv6 Address Of The Geographical Distribution And Related Agreements To Improve

RFC 1287(Towards the Future Internet Architecture) was distributed in 1991 which discussed the future Internet Architecture, lifted the curtain on Ipv6. After then, intelligent people did much for it. But the application about Ipv6 hadn't a great development.The article discussed the foundation of Internet Protocol-definition of IPv6 unicast addresses. The author suggests that Ipv6 unicast addresses should adopt Geographic Based Unicast Addresses, not Aggregatable Global Unicast Addresses.Geographic Based Unicast Addresses is not a new viewpoint of the author, it was suggested in RFC1884 but was obsoleted in RFC2373. The author analyze this address format and think it better. Now although Ipv6's suggestion-Aggregatable Global Unicast Addresses-can attain the similar result as Geographic Based Unicast Addresses by planning well in the prophase of application, factitious factors always exist in the system that will conceal the danger about random from the flexibility. Besides another matter about route is maybe underestimated. It would be more than offset If only thinking transition and cost from Ipv4 to Ipv6 lead to low efficiency.After analyzing Geographic Based Unicast Addresses carefully, the author suggest that the grade route table would make a full route gather, so that the route table's expansion coming with the network's augment and computer's increasing would not be worried. At the same time there would be better service for the network data packet, because the little route table can record several paths that make it possible thinking paths' throughput and delay times when routing.At the same time, the article analyzes the transition strategy from Ipv4 to Ipv6 and points out the shortage of the current transition strategy.And the article researches the improvement of the related protocol based Geographic Based Unicast Addresses, particularly given a new algorithm about Mobile IP. the algorithm is based the two uniqueness of Ipv6 address: uniqueness ofIpv6 address and uniqueness of the computer's interface identification, it can reduce the number of data packet transmitted and raise the efficiencies of communication between computers when the same function is offered.
