校园网络因用户多、应用广、流量大,常使网络出口设备不堪重负,成为网络瓶颈。本文以节约成本、合理利用现有资源为原则,利用策略路由技术实现出口的分流,从而达到消除网络瓶颈的目的,同时也达到一定的负载均衡和更方便的网络管理。 Due to the large number of users in the campus network, wide application and large traffic, network outlets often become overwhelmed and become the bottleneck of the network. In this paper, the principle of cost-saving and rational use of existing resources is exploited, and the strategy of routing is used to realize the egress of the egress, so as to eliminate the bottleneck of the network and to achieve some load balancing and more convenient network management.
