因特网路由协议研究综述

Research on Internetwork Routing Protocol:a Survey

路由器是因特网组网的关键设备,而路由器的主要功能是运行路由协议,并与其它路由器交换路由信息形成本机上的路由表,同时根据路由表的信息正确转发分组。在Internet中,路由协议至关重要,它直接影响网络的性能。近年来,路由协议领域中开展了大量的研究工作,有力地推动了Internet的发展。本文总结了当今Internet上所使用的单播、组播、QoSR、移动等路由协议的研究现状,并分析了进一步的研究方向。

Router is the key eq ui pment to construct an Internetwork.The functions of router are to run routing pr otocol and exchange rout-ing messages with neighbor to form routing table,and d eliver packets correctly.Routing protocol is very important to Internet,and it a ffects the performance of network directly.In recent years,a large amount of wor k has been done on routing research,which develops Internet greatly.In this pape r,after summarizing the research work on uni-cast,multicast,QoS,mobile routing p rotocol,open problems in this area are also discussed.
