摘要

为解决广域网出口部分的流量调度问题，提出了基于SR Policy/EPE的流量调度优化方法，在运营商网络上模拟实现了互联网出口流量调度方案。所提方法通过有效操控业务流量的流向，可实现端到端的流量分配和全网流量灵活调度，在保证用户体验的前提下，有效提高骨干链路的利用率，优化网络整体结构，极大提升了网络的可扩展性。对于各项性能指标应用SR性能测量功能，可选择最优或次优链路以解决广域网出口拥塞问题，证实了所提方案的可行性。

Abstract

In order to solve the traffic scheduling problem of the WAN exit part

a traffic scheduling optimization method based on SR Policy/EPE was proposed

which simulated and implemented an Internet egress traffic scheduling scheme on the carrier network.The proposed method that can effectively control the flow of business traffic to achieve end-to-end traffic distribution and flexible scheduling of network-wide traffic.Under the premise of ensuring user experience

it effectively improved the utilization of backbone links

optimized the overall network structure

and greatly improved increased network scalability.Apply SR performance measurement function to various performance indicators

and choose the optimal or suboptimal link to solve the WAN exit congestion problem

which proves the feasibility of this solution.
