Design and Implementation of State Machine Based Distributed Transaction 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 and etc to be flexible, programmable, and cost-effective. This paper researches on the transaction mechanism in ForCES router, based on the analysis of transaction requirement of ForCES, two phase commit algorithm is introduced and a state-machine based transaction implementation scheme is proposed. ForCES router test bed is built. The experiment result verifies the correctness and feasibility of the transaction mechanism proposed and implemented.
