高校多运营商网络出口策略的分析与研究

Analysis and Research on the Export Strategy of Multi-operator Network in Colleges and Universities

为了保障对互联网的快速访问,大多数高校从多个运营商购买网络出口带宽用于校园网与互联网进行连接。不同的运营商网络出口带宽不同且质量也有差异,导致在网络运行中用户体验不佳、出口带宽利用率不平均等问题,为此,优先使用目的地址路由和智能DNS技术进行出口流量调度,再通过策略路由和负载均衡技术实现出口流量的自动微调,最后通过对网络应用流量的引流与控制完成应用层流量的均衡分配,最终实现在提高用户体验的基础上提高网络出口带宽的利用率。

In order to ensure the rapid access to the Internet,most colleges and universities buy network bandwidth from several operators for the campus network and connect to the Internet.But different operators have different export network bandwidths and different quality.It results in poor experiences of the network operation users.The export bandwidth utilization is not uniform.The paper proposes the priority of the use of destination routing and intelligent DNS technology for export traffic scheduling,the policy of routing and load balancing technology to achieve automatic adjustment of export traffic,and finally the network application of traffic drainage and control to complete the application layer flow balance distribution.These ultimately improve the user experience on the basis of improving the utilization of network export bandwidth.
