近年来，人们对软件定义网络（SDN）/OpenFlow越来越感兴趣，这是一种分离控制平面和数据平面的新型网络架构。支持SDN的产品也被广泛部署在许多生产网络中，旨在绕过当前互联网架构的限制。在构建软件定义路由平台（SDRP）方面有几项努力，该平台将SDN/OpenFlow集成在IP路由中。然而，据我们所知，有一些成功的工作，实现SDRP尽管SDN的灵活性和丰富的功能。在本文中，我们调查国家的最先进的作品对SDRP。我们已经评估了一个主流的SDRP命名为RouteFlow的性能。我们的评估已经进行了使用模拟器Mininet和一个真实的测试床与物理开关。不同于其他作品，我们专注于路由平台的弹性方面。评估结果表明，RouteFlow是弹性的单链路和多链路故障。此外，RouteFlow提供的OSPF实现了比传统OSPF更短的故障转移时间。在RIPv 2的情况下，RouteFlow的协议具有与分布式协议相当的性能值。
In recent years, there has been an increasing interest in Software Defined Networking (SDN)/OpenFlow, which is a novel network architecture splitting control and data planes. The SDN-enabled products have also been widely deployed in many production networks aiming to bypass the limitations of current Internet architecture. There are several efforts on building Software Defined Routing Platform (SDRP), which integrates SDN/OpenFlow within IP routing. However, to the best of our knowledge, there are a few successful works on realizing SDRP despite of the flexibility and rich features of SDN. In this paper, we investigate state-of-the-art works towards SDRP. We have evaluated the performance of a mainstream SDRP named RouteFlow. Our evaluations have been conducted using both the emulator Mininet and a real testbed with physical switches. Different to other works, we focus on the resilience aspect of the routing platform. The evaluation results show that RouteFlow is resilient against both single and multiple link failures. Additionally, OSPF provided by RouteFlow achieves a shorter failover time than the legacy OSPF. In the case of RIPv2, RouteFlow's protocol has a comparable performance value with the distributed one.
