Abstract
A data switch includes ingress ports associated with ingress queues (3) and egress ports associated with egress queues (9). The length of the ingress queues (3) is measured, and the level of broadcast packets arriving at the ingress ports is thereby estimated. Based on this estimate it is determined whether or not the level of broadcast packets is excessive, and in this case broadcast storm control is carried out.
