OPN02-6: Achieving Complete Control Plane Recovery in Optical User Network Interface

In this paper, a new control plane recovery mechanism for optical user network interface is proposed against ingress nodal failure. Current standards of IETF and OIF only provide mechanisms to recover transit and egress nodal failure, while ingress nodal recovery hasn´t been covered yet. Introducing an upstream recovery path message into nodal fault recovery, the proposed mechanism can be applied to ingress nodal recovery and thus reinforce control plane recovery. Detailed signaling flow is presented and simulation results show that the recovery time is cut down by the proposed mechanism. The proposed mechanism provides better interoperability between IETF and OIF standards.
