Abstract
A system that processes single stream multicast data includes multiple queues, a dequeue engine, and/or a queue control engine. The queues temporarily store data. At least one of the queues stores single stream multicast data. A multicast count is associated with the single stream multicast data and corresponds to a number of destinations to which the single stream multicast data is to be sent. The dequeue engine dequeues data from the queues. If the data corresponds to the single stream multicast data, the dequeue engine examines the multicast count associated with the single stream multicast data and dequeues the single stream multicast data based on the multicast count. The queue control engine examines one of the queues to determine whether to drop data from the queue and marks the data based on a result of the determination.
