Abstract
A system, device, and method for allocating virtual circuits in a communication network allocates a virtual circuit for a particular device, establishes a tunnel for communicating with a second device, and maps the virtual circuit to the tunnel based upon an address resolution request received over either the virtual circuit or the tunnel. Protocol messages received over the virtual circuit are forwarded over the corresponding tunnel. Protocol messages received over the tunnal are forwarded over the corresponding virtual circuit.
