基于SDN的多级多域路由算法研究
首发时间:2018-11-08
摘要:近年来,基于SDN架构的路由方案已经被应用于多种网络场景中,现有的路由算法大多无法根据多个域网络状态的变化,例如域间链路状态和流量分布的变化做出动态的调整。对此,针对SDN-WAN网络,我们提出一种基于软件定义网络多级多域的动态路由算法。该算法将网络划分为多个域,根据链路负载状态和流量分布情况等,域间和域内采用不同的路由策略进行路由选择。仿真实验结果表明,与等价多路径算法和基于网络性能的路由算法相比,该算法能够提高多个域网络的平均链路利用率,优化网络时延,并且降低了路径计算复杂度。

Muti-level And Muti-domain Routing Alghrithm Based On SDN
Abstract::Most of the existing routing algorithms can not adjust dynamically based on changes of the states of multiple domain network, such as inter-domain link state and flow distribution. To solve this problem, we propose a muti-domain dynamic routing Algorithm based on SDN-WAN. The algorithm divides the network into multiple domains. According to the link load status and traffic distribution, different routing strategies are adopted between domains and within domains. Simulation results show that, compared with the equivalent multipath algorithm and the routing algorithm based on network performance, the algorithm can improve the average link utilization of muti-domain network, optimize network delay, the reduce the complexity of path calculation.
