A self-recovery scheme for service function chaining

Service function chaining provides a new service deployment model that delivers the traffic along the predefined logical paths of service functions with no regard of network topologies or transport mechanisms. The traffic path of service functions needs to be recovered at failure of the service functions but it may incur a signaling delay among control-plane and data-plane components. In order to shorten the delay of the path recovery at the failure, we propose a self-recovery scheme that temporally recovers the traffic path from the failure by shifting the responsibility of a service function in failure to another service function with data-plane signaling.
