摘　　要：随着网络的快速发展,网络新业务不断增加,网络流量急剧增长,IPv4网络已不能很好地满足人们对网络性能和功能的需求。相对于IPv4,IPv6具有更丰富的地址资源,更可靠的安全性及高效的路由性能等优点,且IPv4地址资源已经枯竭,所以IPv6最终将会取代IPv4。现在正处于IPv4向IPv6过渡时期,很多过渡技术被提出和应用,比如双协议栈技术、隧道技术等。向IPv6过渡是一个漫长的过程,IPv4与IPv6共存的现象将会持续很长时间。同时,网络的快速发展对路由器的性能要求不断提高,而基于转发与控制分离思想的分布式路由器能大大提高路由器性能,实现报文线速转发,很好地满足这一要求。因此,研究分布式路由器的IPv4/IPv6转发控制架构,对提高核心路由器的性能和推动IPv6网络发展具有很重要的意义。With the rapid development of internet,both new applications and internet traffic have increased very quickly,internet with IPv4 already can＇t meet people＇s requirement about its performance and function.Compared with IPv4,IPv6 has many advantages,such as a huge amount of address resource,reliable security,and high routing efficiency,moreover address resource of IPv4 already dried up,so IPv6 will finally replace IPv4.In the transition time from IPv4 to IPv6,many transition techniques are put forward and applied,such as dual-stack technique,tunnel technique and so on.The transition process from IPv4 to IPv6 will need a long time,so internet with IPv4 and IPv6 will coexist during the transition time.Meanwhile,the rapid development of internet puts high requirement to performance and function of router,distributed router based on the idea of forwarding and control element separation can improve router＇s performance greatly and perform wire-rate processing for IP packets,which well meets the requirement of rapid development internet.Therefore,doing research in IPv4/IPv6 forwarding control architecture of distributed router is very significant to improve the performance of core router and promote the development of IPv6.
