IP MPLS POP VIRTUALIZATION AND FAULT TOLERANT VIRTUAL ROUTER

摘要

A method of configuring at least one switch involves configuring the at least one switch to direct communication to at least one of a plurality of computers according to at least one outcome of simulated interaction of a plurality of virtual network routers. A method of simulating interaction of a plurality of virtual network routers involves: causing a first at least one processor circuit to simulate the interaction of the plurality of virtual network routers; and causing a second at least one processor circuit, different from the first at least one processor circuit, to simulate the interaction of the plurality of virtual network routers redundantly to the simulated interaction of the plurality of virtual network routers on the first at least one processor circuit. Apparatuses and computer-readable media are also disclosed.
