Abstract:
A method for routing data packets within a packet network, comprising:receiving a data message from an originating node in a connection-oriented packet network having a plurality of nodes, the message including a first node identifier relating to said originating node and a first request for translation; determining a destination node for said data message based on information in the data message; translating an address for said destination node to a first network routable ATM address based on said first request for translation; selecting a network routing path to said destination node based on said first routable ATM address; routing said data message to said destination node over said path, the destination node formulating and sending out a response message to said data message, the response message including the first node identifier for said originating node, a second node identifier for the destination node, and a second request for translation; receiving said response message from said destination node; determining said originating node based on said first node identifier; translating an address for said originating node to a second network routable ATM address based on said second request for translation; selecting a network routing path to said originating node based on said second routable ATM address; and routing said response message to said originating node.
