<p>An apparatus comprising a switch fabric coupled to a plurality of interfaces and configured to switch a plurality of universal service transport (UST) multiplexing (USTM) data streams between the interfaces, wherein the USTM data streams comprise packet-switched traffic, circuit-switched traffic, and transitional signaling that indicates a change of state between the packet-switched traffic and the circuit-switched traffic, wherein the transitional signaling does not indicate the state in every octet of the USTM data streams. Also disclosed is a network component comprising at least one processor coupled to a memory and configured to receive a data that corresponds to a flow, identify the flow using a flow map, determine whether there is a change in a state of the flow, send transitional signaling on a USTM data stream that indicates the state of the flow if the state of flow has changed, and send the data on the USTM data stream.</p> |
