Zusammenfassung:Methods, systems, and computer program products for controlling enqueuing of packets in an aggregated queue including a plurality of virtual queues are disclosed. According to one method, packets are received at the input side of a queuing system. Each packet is classified into a virtual queue corresponding to one of a plurality of output queues. The output queue sends backpressure messages to the enqueue controller. The enqueue controller determines whether to place the packets in the aggregated queue based on the backpressure messages.
