Abstract
Prioritized subclasses of cells within at least one quality of service (QoS) level in an asynchronous transfer mode (ATM) network element are described. Corresponding QoS queues are provided with one or more thresholds for intelligent discard of incoming cells within a QoS, based upon cell priority, at the onset of queue congestion. Cells having a first priority within a QoS are discarded as a first queue threshold is achieved; cells having a higher priority are enqueued. A cell loss priority (CLP) bit is employed to provide a further degree of cell discard prioritization. Different traffic streams within a single queue have different priorities, enabling intelligent discard of lower priority traffic prior to complete queue congestion.
