基于策略路由和NAT的多出口校园网仿真实验设计

Design of Simulation Experiment of Routing and NAT in Multi-outlet Campus Network Based on Policy

原有一条ISP出口链路已不能满足校园网日常应用需求,文章提出了增加校园网ISP出口链路,并在校园网出口路由器上应用策略路由和NAT技术的解决方案,不仅给出了详细的配置过程,而且还模拟了在出口链路发生故障情况下,数据包的路由过程.测试证明该方案实现了多出口校园网流量负载均衡和链路备份,满足了校园网日常应用需求.

The original ISP outlet link can not meet the daily application requirements of campus networks.This paper proposes solutions to increase the ISP outlet link of campus network and applies policy based routing and NAT technology on the campus network router.This paper not only gives the configuration process in detail,also simulates the routing process of the data packet under the condition of the failure of the export link.The test proves that the scheme realizes the load balancing and link backup of multi-outlet campus network,and satisfies the daily application demand of campus networks.
