Optimization of connection paths in a communications network

Abstract From the Canadian patent

A method for optimizing an established call routed across a network from an originating exchange to a destination exchange over a first connection path. The first, connection path features a path metric of interest such as administrative , weight. A second connection path is identified which features an improved path metric the path, is made operative and the call is directed over the second connection path. Thereafter, the first connection path may be dismantled. The second connection path is preferably, identified by signalling a call set-up message over the network wherein the , message, incorporates a reporting field and each transiting exchange propagating the message, updates the …
