  • Methods and apparatus for differentiated services over a packet-based network
    Patent number: 8023521
    Abstract: Methods and apparatus for the provision of differentiated services in a packet-based network may be provided in a communications device such as a switch or router having input ports and output ports. Each output port is associated with a set of configurable queues that store incoming data packets from one or more input ports. A scheduling mechanism retrieves data packets from individual queues in accord with a specified configuration, providing both pure priority and proportionate de-queuing to achieve a guaranteed QoS over a connectionless network.
    Type: Grant
    Filed: November 21, 2008
    Date of Patent: September 20, 2011
    Assignee: Enterasys Networks, Inc.
    Inventors: Leon K. Woo, Robert Ryan, John B. Crowther
