Abstract
The route calculated by the routing portion of a connection-oriented protocol between source and destination nodes is further optimized after it is initially calculated. A node X that is part of the calculated route receives or generates a connection setup request which contains the calculated route. In response to the setup request, node X examines the nodes in the calculated route to determine if node X knows of a direct link between itself and another node Y in the calculated route that is not adjacent to node X. If such a direct link is known by node X to node Y, then node X replaces that portion of the calculated route from node X to node Y with the known direct link in the connection setup request, and then forwards the connection setup request to the next node in the present calculated route, where the optimization algorithm may be performed again.
