Abstract:
1. A method to centrally reconfigure a connection-oriented network from an existing configuration to a desired configuration, the method including: centrally generating a sequence of configuration specifications for the connection-oriented network, the sequence specifying a plurality of intermediate configurations of a plurality of elements of the connection-oriented network, the intermediate configurations being between the existing and the desired configurations, the generation of the sequence of configuration specifications being made prior to commanding any changes to the existing configuration of the network; and centrally implementing the sequence of configuration specifications within the connection-oriented network by, for each configuration specification, centrally issuing at least one instruction to a plurality of elements of the connection-oriented network to modify configuration information maintained at the plurality of elements to thereby instantiate respective configurations, wherein the implementing includes commanding the plurality of elements to execute specific instructions to instantiate a subsequent configuration specification only if acknowledgments are received from each of the plurality of elements that a preceding configuration has been successfully instantiated, wherein multiple instructions are issued to multiple nodes of the connection-oriented network, the multiple nodes being included within an old route and a new route for a connection in sequential configuration specifications of the sequence of configuration specifications.
