This article describes an address structure which simplifies the routing of frames for a shared access link network. Fig. 1 shows a topology for a ring network. The network includes a backbone ring coupled through communication adapters 10, 12 and 14, respectively, to bridge 1, bridge 2 and bridge 3. Likewise, bridge 1, bridge 2 and bridge 3 are coupled through communication adapters 16, 18 and 20 to ring 1, ring 2 and ring 3, respectively. A plurality of nodes, including a service node, are coupled to the rings. Fig. 2 shows a frame structure for routing data between two nodes within the same network. Essentially, a frame transmitted from Node-A to Node-B will carry a TO-ADDR designating Node-B and a FROM-ADDR designating Node-A.
