Abstract
Method and apparatus for providing a control plane across multiple optical network domains is described. In one example, topology and resource discovery is employed in a transport network having a plurality of control domains. Topology information for each of the control domains is summarized to produce summarized topology information. The summarized topology information for each of the control domains is exchanged among the control domains. At each of the control domains, the summarized topology information of each of the control domains is combined to produce combined topology information. The combined topology information is passed among network elements within each of the control domains using an intra-domain routing protocol.
