An optical transport network comprises a number of nodes, or routers, whi ch are coupled together via optical fibers. When a physical link comes up betwe en a node and a neighboring node, a handshake between the node and the neighborin g node recognizes the link such that the node, and the neighboring node, inclu de it in respective link assignment tables.
