  • Methods and systems for providing differentiated quality of service in a communications system
    Patent number: 7321591
    Abstract: A communications system that facilitates the provision of differentiated quality of service is disclosed, including a marker for receiving a packet of data from an application (110), for examining the packet for predefined criteria, for setting the value of QoS bits in the packet based on the predefined criteria, and for forwarding the packet to a multiple Virtual Circuit (multi-VC) bridge (300). The multi-VC bridge (300) is connected to the marker and selects an Asynchronous Transfer Mode (ATM) Permanent Virtual Circuit (PVC) (120, 122, 124) over which to transmit the packet by mapping the value of the QoS bits to a PVC in a mapping table and forwards the packet over the selected PVC to a destination address.

  • System and method for packet bypass in a communication system
    Patent number: 7126916
    Abstract: A method for packet bypass in a communications network includes receiving a plurality of packets, determining whether each packet is a bypass packet or a non-bypass packet, and communicating the non-bypass packets toward a communication link. The method also includes communicating a plurality of the bypass packets toward the communication link between communication of two of the non-bypass packets.
