【摘要】 由于lPv4的局限性及IPv6呈现的巨大优势,1Pv6已被认为是下一代互联网络协议核心标准之一,各主要国家都在积极推进下一代互联网建设。我国于2008年8月,正式启动了CNGI二期的工程,重点解决推动下一代互联网商用化时遇到的一些“产业性”问题,计划在2010年底发展至少50万的试商用用户。此外,国务院在2009年2月还在“振兴计划”中特别强调关于下一代互联网应用的部分。根据规划,我国将发展100个大型门户网站和政府网站,100所高校支持IPv6。所以,IPv6流量将会不断增长,并在将来一段时间内与IPv4长期共存。鉴于目前流控产品主要针对IPv4,缺乏对使用过渡技术的IPv6流量有效控制的现状,分析了Linux下Nerfileter框架的基本原理,结合IPv6协议的实现及Linux下HTB队列实现机制,讨论了在Linux环境下基于NetFilter框架和HTB队列,实现的IPv6的流量控制模块。在实验环境下测试该模块,当仅区分控制Teredo、6to4、ISAPTP及纯IPv6流量时,有理想的控制效果,并为进一步实现控制各种IPv4到IPv6的过渡协议下更为细致的流量控制打下了基础。更多还原

【Abstract】 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。更多还原
