International Classification:

H04L 12/56

US Classification:

370235

Abstract:

Techniques for improving the performance of flow control mechanisms such as Pause are provided. The techniques provide for maintaining a fair distribution of available bandwidth while also allowing for fewer packet drops, and maximizing link utilization, in a distributed system. For example, in one embodiment, techniques are provided for achieving a fair share allocation of an egress port's bandwidth across a plurality of ingress ports contending for the same egress port.

Abstract:

A method for managing recirculation path traffic in a network node comprises monitoring an input packet stream received at an input port of the network node and monitoring a recirculation packet stream at a recirculation path of the network node. A priority level associated with individual packets of the monitored input packet stream is detected and low priority packets are stored in a virtual queue. The method also includes determining an average packet length associated with packets of the monitored recirculation packet stream. The method further comprises queuing one or more of the low priority packets or the recirculation packets for transmission based on the average packet length and a weighted share schedule.
