【摘要】 针对IP骨干网路由规模大、路径多、重叠度高而易绕转的问题,在分析传统BGP路由选路机制缺陷的基础上,采用SDN控制技术,提出了一种支持传统路由设备和OpenFlow设备的路由反射优化方法,并给出了具体实现算法及部署方案。典型应用场景的测试结果表明,国际访问时延平均缩短了30%,验证了方法的有效性。更多还原

【Abstract】 Aiming at rotation problem of route because of large-scale, multi-path, overlap in IP backbone networks,an optimization method for route reflection supported by both traditional routing devices and OpenFlow devices based on SDN controller technology was proposed. At first, the defects of traditional BGP routing mechanism was analyzed in detail. Then, a specific algorithm implementation and deployment scenarios were given. Test results of typical application scenarios demonstrate the validity of the proposed method. The average delay of international access reduces by 30%.更多还原
