ABSTRACT:
An automatic feedback mechanism in a communications network having dynamic routing. The invention detects the failure of an element in a route that is either in the process of being created or has been created and is being used. The invention provides a means for sending information as to the failure of the element back to the node originating the communication and, if the route had been established, to the destination node as well. The information sent back is used to update the network topology data base of the receiving node for subsequent route creation decisions by that node. In this way, proliferation of status messages in a communications network is avoided.
