Abstract:
1. A switch, comprising: a plurality of ingress ports in an input/output section of the switch, said plurality of ingress ports receiving traffic from a corresponding plurality of network devices that are coupled to said plurality of ingress ports via a respective plurality of network communication cables; and a packet rate control module in a processing core section of the switch, said packet rate control module determining whether a combined arrival rate of traffic received on said plurality of ingress ports in said input/output section of the switch exceeds a packet processing rate of said processing core section of the switch in routing said traffic received on said plurality of ingress ports to a plurality of egress ports in said input/output section of the switch, said packet rate control module initiating a delivery of packet rate control messages to said plurality of network devices via said network communication cables upon a determination that said combined arrival rate of traffic received on said plurality of ingress ports in said input/output section of the switch exceeds said packet processing rate of said processing core section of the switch, said packet rate control messages instructing said plurality of network devices to reduce a delivery rate of traffic to said plurality of ingress ports.
