Abstract
A network device for scheduling packets in a plurality of queues includes a plurality of leaky bucket modules, each of the plurality of leaky bucket mechanisms being associated with one of a plurality of queues and configured to process information based on a predefined bandwidth, a scheduler configured to schedule services of the plurality of queues and a metering module for tracking whether or not the plurality of queues has exceeded a predefined threshold through the leaky bucket modules. If the plurality of queues has exceeded the predefined threshold, the metering module is configured to compute a new bandwidth allocation for each of the plurality of queues, the new bandwidth allocation replacing the predefined bandwidth and being proportional to the predefined bandwidth for each of the plurality of queues.
