Abstract
A network switch maintains transmit queues and for each transmit queue a table which identifies the contributions of traffic received at the ingress ports to that queue. When a queue is too long, a pause frame is dispatched from a selected one of the ingress ports. The ingress port may be selected as that making the greatest contribution to the transmit queue. However, a control algorithm allows ports carrying high priority traffic to be excluded from the selection.
