Abstract
A system and method for automatically generating a topology of a network having synchronous optical network (SONET) switches. Switches in the network pass information about itself to other switches in the network so that every switch can maintain a topology of the network. Using this knowledge of the network topology, each switch can generate a communication route within the network and automatically allot bandwidth for the route. Each switch may generate a new route in response to a line failure.
