Abstract
A method to reconfigure a connection-oriented network from an existing configuration to a desired configuration includes generating a sequence of configuration specifications for the connection-oriented network. The sequence specifies a plurality of intermediate configurations between the existing and the desired configurations. The sequence of configuration specifications is implemented within the connection-oriented network by, for each configuration specification, issuing at least one instruction to an element of the connection-oriented network to modify configuration information maintained at the element to thereby instantiate respective configurations. The implementing includes issuing a specific instruction to instantiate a subsequent configuration specification only if an acknowledgment is received that a preceding configuration has been successfully instantiated.
