ForCES (Forwarding and Control Element Separation) architecture brought forward by IETF shows great advantages for network devices such as routers, wireless base stations, etc to be flexible, programmable, and cost-effective.This paper put forward a new high availability scheme for ForCES router. The framework of ForCES devices is firstly introduced. Then based on a revised VRRP protocol, a primary CE election mechanism is proposed and the kinds of ForCES information to be backuped are thoroughly analyzed. Next, system implementation issues are considered. Finally, a ForCES high availability router testbed is constructed, experiment results on it verifies the correctness, feasibility and efficiency of the proposed high availability scheme.
