Research and Design of the Pseudo-VRRP Based High Availability Mechanism in the ForCES Router

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.
