Abstract:
1. A multiport network device comprising: a plurality of receive ports configured to receive frames in a packet-switched network, the frames each having a source field indicating the source of the frame and a destination field indicating an intended destination for the frame; a plurality of transmit ports configured to transmit the frames in the packet-switched network; a time-stamping component connected to receive the frames from the plurality of receive ports, the time-stamping component appending a time-stamp value to the received frames that correspond to voice transmissions; and output queues corresponding to the transmit ports and connected to receive the frames from the output of the time-stamping component, the output queues forwarding the received frames to appropriate ones of the transmit ports, the output queues expediting the forwarding of the received frames that have appended time-stamp values after a predetermined period of time has elapsed from the time-stamp value, each of the output queues further comprising
