Method and apparatus for providing quality of service across a switched backplane between egress and ingress queue managers |
摘要 |
A method and system is provided to enable quality of service across a backplane switch. An egress queue manager on one blade communicates with an ingress queue manager on the same or on another blade where each blade is connected via a backplane switch. The egress queue managers communicate the congestion to ingress queue managers using a messaging scheme. The ingress queue managers determine when to reduce or resume the packet sending rates of ingress queues mapped to congested egress queues or to destinations on congested blades. Each ingress queue manager maintains information about the status of egress queue congestion on its own blades. Normal rates of dequeuing packets from ingress queues are resumed only when the related congestion on all of the egress queues or related destinations has subsided.
