Abstract
Apparatuses and methods for merging multiple domains into a merged domain and splitting a single domain into multiple domains in an Automatically Switched Optical Network (ASON) are disclosed. For merging, a node in a first domain can be identified to be a new Routing Controller (RC) for the merged domain. A second domain can be identified to be merged with the first domain. Nodes, including old RCs, in the first domain and the second domain are notified of the identity of the new RC in the merged domain. The topology of the old RC's domain is sent to the new RC. The new topology is computed by the new RC from the topology information given by the old RCs. The updated topology is distributed to nodes in the merged domain via the new RC.
