Abstract

In one embodiment, a flow control module aggregates indications of queuing resource utilization at devices attached to a switching fabric within a router and broadcasts that information out of band to all devices attached to the same switching fabric. When the flow control module identifies congestion at one of the attached devices according to the indications, the module may also cause a throttling of traffic sent to the congested device in addition to sending the out of band indication of the congestion to all the attached devices. Flow control modules for each of the attached devices provide local interrupts for reducing outbound traffic to a congested device according to the identification of that remote congestion.
