One Novel Method for NAT-PT of IPv4/IPv6 Translator

From IPv4 to IPv6 is a long evolution process and protocol translation technology will be required during the course of gradual deployment of IPv6. To solve current problem in NAT-PT of IPv4/IPv6 translator, a novel solution which change the session parameters is proposed. This paper contributes the following: Firstly, Bi-Direction translation of IPv4/IPv6 is implemented based on the same address pool, and fragged IP packets can also be translated. Secondly, the Discard rate is decreased to 1/65536 while one IPv4 address serve 2 64 sessions. Thirdly, truly full translation for TCP/UDP/ICMP packet is completed.
