1. A method for routing data through a network comprised of dissimilar linked sub-networks by allowing an originating node to locally compute a path through said network, comprising steps of:

  • providing a network controller associated with said originating node;

    providing at said network controller a plurality of agents, each of said agents representing a particular one of said sub-networks in said network;

    computing a path through a subset of said plurality of sub-networks to a sub-network containing a destination address; and

    querying said agents representing said plurality of sub-networks in said subset for setup information necessary for each of said plurality of sub-networks in said path to pass said data through said sub-network,wherein said step of computing a path to said sub-network containing said destination address comprises steps of;

    consulting a network topology database comprising map data for link connections between said sub- networks;

    determining routing criteria for said data;

    querying said plurality of agents, for which a path to said sub-network containing said destination address exists, regarding said criteria data; and

    selecting a path most closely meeting said criteria data.
