ABSTRACT:
A dedicated IP-based wavelength routing/signaling control plane for optically switched network, is provided. The IP-based control plane is an out-band routing/signaling mechanism and does not require optical-electrical-optical (OEO) conversion. The control plane can accommodate the various network topologies of the data plane and if one of the supervisory, or control channel fails, the IP-based control plane can re-route the traffic to destination. Using non-broadcasting addressable protocols the control plane selects a different path to re-direct the control information without declaring the whole communications trail down and without affecting the client traffic over the data path.
