Abstract
A network device for scheduling packets in a plurality of queues. The network device includes a plurality of configurable mechanisms, each of which is configured to process information in one of a plurality of queues based on a predefined bandwidth. A scheduler services an associated one of the plurality of queues based on the predefined bandwidth. The network device also includes means for tracking whether or not the plurality of queues has exceeded a predefined threshold. If the plurality of queues has exceeded the predefined threshold, a new bandwidth allocation is calculated for each of the plurality of queues. The new bandwidth allocation replaces the predefined bandwidth and is proportional to the predefined bandwidth for each of the plurality of queues.
