1. A method for centralized control of a network, comprising:
- creating an authoritative topology database at a master node of a plurality of nodes of said network, whereineach of said nodes is communicatively coupled to another of said nodes in a mesh topology, by at least one of a plurality of optical links,said authoritative topology database comprises topology information regarding a topology of said network,said master node is configured to manage said network by virtue of being configured to perform a network management activity,said network management activity comprises at least one of discovery, implementation, assurance, and restoration, of a virtual path,said creating said authoritative topology database comprises sending a positive reply from a neighbor node to said master node,said neighbor node is a neighbor of said master node, andsaid reply comprises at least one ofa node identifier for said neighbor node,a node type of said neighbor node, anda system inventory for said neighbor node.

Abstract
A method and apparatus for centralized control of a network is described. The network includes a number of nodes. The method includes creating a database and storing the database on a master node of the network. The database contains topology information regarding a topology of the network. Each of the nodes is coupled to at least one other of the nodes, with the master node being one of the nodes.
