description An approach to queuing data at a network switching node includes assigning a queue value such as a priority value or a weight to each of a plurality of queues which temporarily store data packets to be forwarded toward a link on the network. A bandwidth value related to a maximum amount of data to be transferred on the link is defined. A data limit value is assigned to each of the queues to limit the amount of data that can be forwarded from each queue. The data limit value is derived from the bandwidth value for the link. By placing bandwidth-related limits on the queues, low-priority queues are prevented from being dominated by high-priority queues, that is, low-priority queues are not prevented from forwarding their data by the priority structure. Also, the bandwidth-related limits allow for control of traffic flow to prevent overloading lower-capacity links on the network.
