Abstract:
1. A restoration signaling protocol for restoring service to a service path between an ingress end Optical cross-Connect (OXC) and an egress end OXC over a restoration path in a mesh network comprising: configuring an ingress end OXC to egress end OXC restoration path for the service path when the service path is provisioned; configuring restoration standbys for the restoration path wherein a restoration standby has one lightpath and each lightpath is assigned one wavelength channel; storing the restoration path at the ingress end and egress end OXCs; choosing a control OXC for the restoration path which may be the ingress end OXC or the egress end OXC defining an opposite end OXC; detecting a service path failure; initiating service path restoration comprising:
