Method and apparatus for providing differentiated Quality-of-Service guarantees in scalable packet switches

摘要

The invention comprises a method and apparatus for providing differentiated Quality-of-Service (QoS) guarantees in scalable packet switches. The invention advantageously uses a decentralized scheduling hierarchy to regulate the distribution of bandwidth and buffering resources at multiple contention points in the switch, in accordance with the specified QoS requirements of the configured traffic flows.
