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.
