1. A packet switched communication network including two or more nodes connected by transmission links, each of said nodes containing one and only one control point for providing various routing and control functions, said network comprising:

  • two or more subnodes within one or more of said nodes each subnode having access to said functions provided by said control point within its node;

    intranode communication links connecting the subnodes within the nodes which contain subnodes;

    means in each node for determining optimum routes for packets being sent through the network based on information about subnodes within the network; and

    means in each node for creating an address for one or more user applications connected to one or more subnodes, the address of the form NetID.NodeID,SubnodeID.label where;

    NetID is a one to eight byte unique designation for the network;

    NodeID is a one to eight byte unique designation for a node within said network;

    subnodeID is a one to eight byte unique designation for said one or more subnodes within said node; and

    label designates said one or more user applications connected to said one or more subnodes.
