Abstract
An upstream network device in a switching system processes packets an determines respective one or more egress ports of a downstream network device via which the packets are to be subsequently transmitted by the downstream network device. The upstream network device temporarily stores the packets in respective virtual output queues (VoQs) corresponding to the determined egress ports of the downstream network device. Responsively to receiving a flow control message indicating that particular one or more egress ports of the downstream network device are congested, the upstream network device modulates a flow of packets from particular one or more VoQs corresponding to the one or more particular congested egress ports of the downstream network device, to reduce congestion at the particular congested egress ports of the downstream network device, without modulating the flow of packets from other one or more VoQs corresponding to other egress ports of the downstream network device.
