Claim:
1. A method, in a node operating in a network with a control plane, to optimize wavelength retuning on service redials comprising one or more of modifying a path and a wavelength through the control plane, the method comprising: detecting a failure on a link associated with the node; and for each affected connection on the link, sending a respective release message to an associated originating node via the control plane, the release message including an associated protect path and a wavelength determined by the node instead of by the associated originating node, wherein the release message is utilized by the associated originating node to redial the affected connections with the associated protect path and the wavelength determined by the node, wherein the control plane is a source-based routing control plane with associated originating nodes using the protect path and the wavelength in the release message to redial the affected connections.
