【摘要】 当前Internet互联网的标准协议是IP的第4版,即IPV4,而IPV4由于地址资源枯竭和路由表爆炸等致命问题,已经面临着更新换代的必要。IP第6版,即IPV6是作为IPV4协议的后继者而由因特网架构委员会(IAB)的因特网工程任务组(IETF)设计的新版本的IP协议,有着几乎无限的地址空间和层次化的地址结构,即将成为未来IP网的标准协议。IPV4制定后20多年来已经积累了很多问题,尤其是在其基础上运行的各种网络协议,因而对各种原IPV4下的网络协议向IPV6迁移就成了IPV6设计的一个重要工作。近年来RIP、OSPF等重要的路由协议已经经过不同程度的修改成功迁移到了IPV6下。VRRP是IP协议族的一个重要协议,主要提供了对默认下一跳路由的动态冗余备份,目前还没有被迁移到IPV6下的国际标准,本文以RFC委员会在2004年最新推出的VRRP IPV6草案7作为基础,深入的研究和探讨了VRRP在IPV6下的各种新功能,对草案中增删的各种功能特性分析了其理论根据和优缺点,并对草案中给出的协议状态机在深入分析的基础上给出了改进方案,较好的改善了VRRP的收敛时间和协议功能,最后在Vxworks环境下对其进行了仿真实现。更多还原

【Abstract】 The standard protocol of Internet networks available is the forth edition of IP (Internet Protocol) ,that is IPV4.For two fatal problems“the address exhausted”and“the route table exploring”, It must be replaced by the next generation protocol .The sixth edition of IP ,that is IPV6,is the new next generation protocol designed by the IETF to replace the current version Internet protocol-IPV4. IPV6, which has almost infinite IP addresses and the layered address architecture, is the future standard protocol of IP.IPV4, which is now about twenty years old, is beginning to have many problems, especially for those network protocols which are running based on the IPV4,so it is important for us to amend them to fit IPV6.Recently years, most route protocol such as RIP,OSPF had been amended to fit IPV6 successfully through the respective different changing.VRRP, is an important protocol of IP protocols family, mainly provides a dynamic redundancy backup mechanism of the default next-hop. It has not had the replaced protocol in IPV6 until now. Based on the seventh edition VRRP for IPV6 draft of RFC, the paper shows various new functions of VRRP for IPV6, analyses advantages and theory foundation of the changing of the draft, and improves the VRRP state machine through a deeply analysis in it. This improvement makes the convergence time of VRRP topology less. At the end, we realize the emulation system of the new VRRP in vxworks.更多还原
