基于隧道技术的客户端策略路由研究

目前很多校园、小区、企业单位的网络,除了接入一条主干的ISP运营商提供的网络外,还同时接入多个不同的ISP运营商提供的网络.其目的是根据收费情况的不同最大程度地节省开销外,还使得原来比较脆弱的单一出口有了备份,不会因为一个ISP发生故障而中断和因特网的连接.但是,这种多出口网络体系结构必须解决策略路由的配置问题.探讨了如果通过隧道技术实现在客户端进行策略路由的方法.

ON CLIENT STRATEGY ROUTING BASED ON TUNNELLING TECHNOLOGY

At present,many campuses,residential zones and enterprises access to a network serviced by the backbone network ISP provider,apart from that they also have some other accesses to the networks offered by different ISP operators.This is for the sake of saving the cost to the maximum according to different tolls,and also for making a backup against original single exit which could be relatively fragile,so that the break off from Internet caused by the malfunction of a certain ISP would not incur.However,such m...
