Abstract:
1. A method for managing traffic in a packet-based switch/router that has an input interface for receiving traffic on multiple virtual circuits (VCs) and an output interface for transmitting traffic on multiple VCs, said method comprising: classifying packets into traffic classes; associating said packets with a VC; on a per-VC basis, enqueuing said packets into class-specific queues; and on a per-VC basis, dequeuing said packets from said class-specific queues enqueuing said packets that are dequeued from said class-specific queues into VC-specific segmentation and re-assembly (SAR) queues; and dequeuing said packets from said VC-specific SAR queues according to a dequeuing algorithm that arbitrates among multiple VC-specific SAR queues.
