    摘要： Different levels of service are provided to different types of traffic within a single virtual circuit (VC) by converting the traffic from fixed-length cells to variable-length packets, classifying the packets based on information in the packet headers, associating the packets with a VC, and then implementing class-specific enqueuing and dequeuing of the classified packets on a per-VC basis. Classified packets are dequeued from VC-specific and class-specific queues into VC-specific segmentation and re-assembly (SAR) queues according to an algorithm that is a function of traffic class. The dequeuing algorithm determines the level of service that is provided to the different classes of traffic within each VC. Packets are dequeued from the VC-specific SAR queues and converted back to fixed-length cells according to an algorithm that arbitrates among multiple VC-specific SAR queues. The technique for managing traffic can be carried out within an Ethernet switch/router that includes input and output ATM interfaces.

    摘要： An amplifier circuit. In one embodiment, the amplifier circuit includes an output stage and a gain stage. The gain stage includes first and second differential output terminals that may be coupled to first and second differential input terminals of the output stage. The gain stage includes a first feedback loop and a second feedback loop. First and second half-stages within the gain stage may be coupled to provide the second feedback loop. The first half-stage may be coupled to control a first output current at the first output terminal of the gain stage, while the second-half-stage may be coupled to control a second output current at the second output terminal of the gain stage.
