摘要： A method of signalling a message using a terminal address across multiple network entities is provided. At least two contiguous network entities are associated with addressing spaces for which message addresses are not routable by way of the terminal address and are not otherwise routable by way of a single address. The method stores a terminal address of either an originating or terminating network entity. At every network border between any two contiguous network entities wherein an immediately succeeding network entity does not provide an address through which the message is routable, it is determined whether the address is to be stored and replaced with another address. If so, the address is stored so as to permit its subsequent retrieval. Once the address has been stored, the another address is assigned to be the address and the message is routed in the succeeding network using the another address.

摘要： There is provided a method of signalling a message using a terminal address across multiple network entities. At least two contiguous network entities are associated with addressing spaces for which message addresses are not routable by way of the terminal address and are not otherwise routable by way of a single address. At every network border between any two contiguous network entities wherein an immediately succeeding network entity does not provide an addressing space through which the message is routable, it is determined whether the party number is to be stored and replaced with a new party number. If so, the party number is stored so as to permit its subsequent retrieval according to a last-in and first-out precedence to thereby create a stored party number. Once the party number has been stored, a replacement address is assigned as the party number. Also at every such border, it is determined whether the party number is to be discarded and replaced with a stored party number. If so, the last-in stored party number is assigned as the party number. The message is then routed according to the party number and, with the message, every stored party number is transported through the immediately succeeding intermediate network entity and through each further succeeding and contiguous intermediate network entity, if any, through which the message is routable.

摘要： A method and apparatus for providing distributed communication routing includes a route computation engine operably coupled to a plurality of forwarding engines within a logically distributed router. Registration information is provided to the route computation processor by the forwarding engines, and the forwarding engines are recognized and identified by the route computation processor in response. The registration information includes information regarding interfaces or connections amongst the forwarding engines and external routers and other external destinations. The route computation processor provides control information to at least one of the plurality of forwarding engines for distributed routing maintenance and/or specific data forwarding operations. Distributed routing maintenance includes monitoring the status of the forwarding engines, while specific data forwarding operations include tunneling messages relayed to and from the route computation processor by the forwarding engines and packet formatting information that controls how the format of packets forwarded by a forwarding engine.
