Claim Text:
1. A localized repair method in a network using a control plane, comprising: responsive to a failure on a local repair segment defined on a connection traversing the network, generating a release message in the control plane, wherein the local repair segment is one of (i) between optical-electrical conversion points of the connection and (ii) a High Order (HO) Optical Transport Network (OTN) multiplexing segment of the connection, and wherein the local repair segment comprises multiple spans that are determined based on an attribute of either a photonic domain for (i) or an OTN domain for (ii); attempting a local repair on the local repair segment; if the local repair is unsuccessful, transmitting the release message to redial the connection; and if the local repair is successful, signaling a new sub-path based on the local repair.
