Abstract

In traditional networks, the pre-routed packets are dropped during the link failure leading to a huge data loss. Survivability techniques such as protection and restoration are available to provide the solution before and after the link failure. But, the new flow entries that are to be added in the flow table increase the initial network demand leading to an increase in memory demand per switch. The saved data not only reduces the network speed but also demands of repeated processing of entries. In this paper, we propose a new scheme of Group Table based Rerouting (GTR) technique to find the response against single link failure through Fast Fail-over (FF) group table feature provided by OpenFlow. This scheme provides equal roles for both controllers and forwarding OpenFlow enabled switches. Here, the controller maintains a look-up table which is updated periodically according to the change in network structure. Also, it has to update the FF group table simultaneously corresponding to every active port of the switches. The controller relabels the packets and updates the flow entries on respective switches.

软件定义网络中的链路故障恢复机制

在传统网络中，由于链路故障导致预路由报文丢失，导致大量数据丢失。保护和恢复等生存性技术可用于提供链路故障前后的解决方案。但是，要添加到流表中的新流项会增加初始网络需求，从而导致每个交换机的内存需求增加。存储的数据不仅降低了网络速度，而且减少了重复处理条目的需求。在本文中，我们提出了一种新的基于组表的重路由(GTR)技术方案，通过OpenFlow提供的快速故障转移(FF)组表特性来寻找对单链路故障的响应。该方案为控制器和转发OpenFlow的交换机提供相同的角色。在这里，控制器维护一个查找表，该查找表根据网络结构的变化定期更新。此外，它必须同时更新FF组表对应于交换机的每个活动端口。控制器重新标记数据包并更新各自交换机上的流项。
