Abstract:
A method of operating a network, said method comprising:grouping a plurality of nodes into zones, wherein said network includes said plurality of nodes, at least one of said nodes in each one of said zones is a boundary node, each boundary node in each one of said zones is coupled to a boundary node in another of said zones by one of a first number of inter-zone optical links, a one of said zones includes a number of said nodes, and each one of said number of said nodes is coupled to at least one other of said number of said nodes by one of a second number of intra-zone optical links; configuring a non-boundary node to transmit network topology information to other of said nodes, said non-boundary node being a one of said number of said nodes that is not one of said boundary nodes; and configuring a boundary node of said number of said nodes to limit transmission of said network topology information through said boundary node to other of said boundary nodes.
