摘要
校园网出口一直以来都是众多高校所关心的问题。本文提出了一种在多出口校园网环境中,利用策略路由(PBR)和网络地址转换(NAT)等技术有效的解决了多出口负载均衡、国际流量费用和网络瓶颈的技术方案。在合理使用现有CERNET网络资源的同时,还可使用当地ISP提供的带宽高速上网。
The exit of campus network has always remained a headache for colleges and universities. The present paper introduces a technical approach in the multi - exit - link campus network to solving effectively the problems of balanced load of multi - exits, international rate of flow expense and network bottleneck by means of PBR and NAT. The solution makes use of all available resources provided by CERNET and local ISP.
