1. For a network switch including a mesh of interconnected network switch nodes, a network switch node comprising:

  • a set of ports having more than two members, and the ports in the set including respective medium access control units for transmission and reception of data frames according to a network protocol, the ports in the set of ports being connectable to a port on another network switch node inside the mesh, or to a network communication medium outside the mesh; and

    node route logic, coupled with the set of ports, which monitors frames received by the set of ports to route a received frame for transmission according to the network protocol to a selected port in the set of ports, including logic to select the selected port according to rules for navigating through the mesh inside to the network switch, and wherein the node route logic forwards the received frame for transmission to a default location of a multiprotocol router resource associated with the switch when the node route logic cannot otherwise determine a route for the received frame.
