摘要

软件定义网络(SDN)数据平面的网络故障快速恢复是无缝支持实时通信的严格要求。IETF标准化了多拓扑路由(MTR)，它通过计算不同链路权重的虚拟拓扑(vt)在路由表中提供冗余。基于MTR的故障恢复技术使用vt，其中每个vt都为物理拓扑中的某些链路分配了非常高的权重，以便这些链路不会被最短路径遍历。当某个网络组件发生故障时，将激活隔离该组件的VT对应的路由表进行流量转发。本文定义并实现了SDN中基于MTR的故障保护(MTR- p)体系结构，并在不同的网络拓扑结构下分析了其性能。实验结果揭示了MTR-P在SDN中快速故障恢复的重要特性。

Multi Topology Routing Based Failure Protection for Software Defined Networks

The fast recovery from network failures in the data plane of Software Defined Networks (SDN) is a stringent requirement to seamlessly support the real-time communications. IETF standardized Multi Topology Routing (MTR) which provides a redundancy in routing tables by computing virtual topologies (VTs) which differ in their link weights. MTR based failure recovery techniques use VTs each of which assigns a very high weight to certain links in the physical topology so that these links are not traversed by the shortest paths. When a network component actually fails, the routing tables corresponding to the VT isolating the component are activated for traffic forwarding. In this paper, the architecture for MTR based failure protection (MTR-P) in SDN is defined and implemented, and its performance is analyzed using different network topologies. The experimental results expose important properties of MTR-P for fast failure recovery in SDN.
