摘要

A credit-based buffer control scheme for an input-buffered/output-controlled switch allocates turns to release protocol data units deterministically among transmit queues storing groups of protocol data units entitled to different qualities of service. Receive queues may be constructed dynamically within a shared output buffer to accommodate non-uniform traffic patterns. In a LAN or WAN packet switch implementation, transmit queue data release rates over a period of sustained operation are made independent of the length of protocol data units presented for release by employing a "burst"-based release strategy.
