基于多路由配置的数据中心网络故障恢复研究

摘要

针对数据中心网路故障恢复问题,提出一种使用多路由备份配置MRC(Multiple Routing Configuration)的IP快速恢复算法.通过研究MRC主动恢复过程对数据中心网络中链路负载分布的影响以及网络链路利用率的分布,在最短路径算法中引入自适应权重分布模型.该模型能有效地分离高负载链路的数据流量到其他可用链路,减少网络拥塞.实验结果表明,对比传统的MRC算法,改进后的算法(Modified MRC)能够通过有效降低最大链路利用率来实现更均衡的网络流量负载分布.%Aiming at the fault recovery of datacenter network, this paper proposes a IP fast reroute recovery algorithm using multiple routing configurations(MRC).By studying the impact of MRC recovery process on the load distribution over datacenter network links and the distribution of link utilization, we introduce an adaptive weight load balance model in the shortest path algorithm.This model can effectively split the traffic on high load links to other links, in order to reduce network congestion.Experimental results show that compared with traditional MRC algorithm, the modified algorithm achieves more balanced load distribution of network traffic by reducing the maximum link utilization.
