Research on Survivability of Software Defined Wide Area Network Control Plane

LI Jiliang;LOU Yang;ZHANG Xuemin;The 54th Research Institute of CETC;  
The software defined wide area networking control plane has such problems as large routing calculation load,low survivability,etc.Aiming at these problems,this paper analyzes the reason that the typical clustered control structure is difficult to apply to SDN.The controller task assignment and route computing method under this architecture is studied,and a survivability networking method is proposed.The experiment results show that this method can implement data communication when the controller is in failure to ensure high-survivability application of SDN controller networking architecture in wide area network(WAN).
