Research And Technique Of IPv6 Flow Control Based On NetFilter Framwork

As designed to meet the requirements for quantity and quality of future network infrastructure。IPv6 protocol solves the problems faced by current IPv4 protocol,has been considered the key of Next Generation Network。Every major countries are actively promoting the next generation Internet development。China in August 2008,officially launched the second phase of the project CNGI,focusing on solving the next generation of Internet business encountered of the "industry" problem,the development plan by the end of 2010 at least 500,000 commercial trial users。In addition,the State Council in February 2009 was still "Revitalization Program" with particular emphasis on the part of the next generation of Internet applications。According to the plan,China will develop 100 major portals and government websites,100 colleges and universities to support IPv6。Therefore,IPv6 traffic will continue to grow,and some time in the future long-term coexistence with IPv4。In view of traffic control products are mainly for IPv4 protocol,IPv6 traffic which using IPv4/IPv6 transition mechanisms is on the lack of effective control。analyzing the mechanism and the expansion of Linux NetFilter framwork,combined with Linux IPv6 protocol implementation and the realization of HTB queue,based on Linux NetFilter Framework and HTB queue discussed to achieve the IPv6 flow control module。In the experimental environment to test the module,when the only distinction between network flow of Teredo,6to4,ISAPTP and IPv6 traffic,there is an ideal control effect,and further to achieve control of a variety of IPv4 to IPv6 transition agreement to lay a more detailed flow control the foundation。...
