Abstract

Some embodiments provide a network forwarding integrated circuit (IC) including multiple configurable ingress pipelines, multiple configurable egress pipelines, a traffic management unit, and a statistics bus. The configurable ingress pipelines are for processing packets received from ports of the network forwarding IC. The configurable egress pipelines are for processing packets to be transmitted out the ports of the network forwarding IC. The traffic management unit includes multiple queues, each of which corresponds to one of the egress pipelines, and is for receiving a packet from an ingress pipeline and enqueuing the packet into one of the queues. The statistics bus connects the traffic management unit to at least a subset of the ingress pipelines, and is for providing the ingress pipelines with state information regarding the queues.
