摘　　要：软定义网络(SDN)是一种新型的网络架构,其将控制平面和数据转发平面分离,并为网络管理提供了可编程的接口,简化了网络管理。随着基于OpenFlow的SDN技术在现实中的广泛应用,其所存在的问题也凸显出来,可靠性就是其中的一个重要方面。文中针对基于OpenFlow的SDN在可靠性方面存在的问题,分析总结了导致OpenFlow网络失效的因素,将网络失效划分为控制器、链路和节点失效,并归纳出相应的解决方案,探讨了未来基于OpenFlow的SDN在可靠性方面的研究方向与趋势。SDN is a new type of network framework that separates control plane and forwarding pIane and provides network management with programmable interface for easier SDN network management. With the increasing application of OpenFlow-based SDN, its problems have also been revealed among which reliability is of great importance. This paper analyses factors that causing network failure, classifies network failure into controller, link and node failure, and presents solutions concerned. Finally the trend of future study on the reliability of OpenFlow-based SDN is pointed out.
