Patent ID: 7711828

Claim:
A method of, at a client call controller interfaced to a connection-oriented network, requesting the establishment of a second call from a source to a destination on the connection-oriented network, where a path for said second call uses path segments distinct from path segments used in a previously determined path for a first call on the connection-oriented network, said method comprising the steps of: receiving a call processing message including encrypted network information at the client call controller from one of a plurality of network call controllers on the connection-oriented network; and sending a call request message to one of the plurality of network call controllers on the connection-oriented network requesting establishment of said second call, where said call request message includes said encrypted network information, wherein said first call represents an agreement to communicate over a first path through the connection-oriented network from the source to the destination, the first path being implemented on the connection-oriented network using a first series of links interconnecting the source and the destination, and wherein said second call represents an agreement to communicate over a second path through the connection-oriented network from the source to the destination different than the first path, the second path being implemented on the connection-oriented network using a second series of links interconnecting the source and the destination different than the first set of links.
