ABSTRACT:
The present invention provides systems and methods to mix In-Band (IB) and Out-of-Band (OOB) signaling mechanisms under the Private Network-to-Network (PNNI) protocol for optical control plane connectivity. The present invention provides mechanisms for establishing and controlling OOB control plane communications. By default, the mechanisms treat all links as IB to discover nodes and links using IB mechanisms. For any blocked links, the link can be configured as OOB if there is a data communication network (DCN) connection to the remote node.
