The method includes a step of establishing one or more Virtual Local Area Networks (VLANs). Each VLAN comprising a subset of the plurality of packet switches operatively coupled to the given circuit switch. At least one of the one or more VLANs comprises the at least one packet switch to which the source and destination nodes are operatively coupled.
