软件定义网络中的认知路由引擎

Towards a Cognitive Routing Engine for Software Defined Networks

Imperial College(帝国理工学院)

摘要:

大多数软件定义网络(SDN)流量工程应用使用过多且频繁的全局监控,以便为网络的当前状态找到最佳服务质量(QoS)路径。在这项工作中,我们提出了一个SDN应用程序的动机,架构和初始评估,称为认知路由引擎(CRE),它能够找到接近最优路径的用户指定的QoS,同时使用一个非常小的监测开销相比,全球监测,这是需要保证最优路径被发现。较小的监测开销带来的优势,较小的响应时间的SDN控制器和交换机。GEANT学术网络的SDN表示上的CRE的初始评估表明,可以找到接近最优的路径,最优性差距为1.65%,同时使用9.5倍的监控。

英文摘要:

Most Software Defined Networks (SDN) traffic engineering applications use excessive and frequent global monitoring in order to find the optimal Quality-of-Service (QoS) paths for the current state of the network. In this work, we present the motivations, architecture and initial evaluation of a SDN application called Cognitive Routing Engine (CRE) which is able to find near-optimal paths for a user-specified QoS while using a very small monitoring overhead compared to global monitoring which is required to guarantee that optimal paths are found. Smaller monitoring overheads bring the advantage of smaller response time for the SDN controllers and switches. The initial evaluation of CRE on a SDN representation of the GEANT academic network shows that it is possible to find near-optimal paths with a small optimality gap of 1.65% while using 9.5 times less monitoring.
