    摘要： The decision within a packet processing device to transmit a newly arriving packet into a queue to await processing or to discard the same packet is made by a flow control method and system. The flow control is updated with a constant period determined by storage and flow rate limits. The update includes comparing current queue occupancy to thresholds and also comparing present queue occupancy to previous queue occupancy. The outcome of the update is a new transmit probability value. The value is stored for the subsequent period of flow control and packets arriving during that period are subject to a transmit or discard decision that uses that value.

    摘要： A method and system for controlling a flow of a plurality of packets in a computer network is disclosed. The computer network includes a queue. The method and system include determining a queue level for the queue and determining an offered rate of the plurality of packets to the queue. The method and system also include controlling a transmission fraction of the plurality of packets to the queue, based on the queue level, the offered rate and a previous value of the transmission fraction so that the transmission fraction and the queue level are critically damped if the queue level is between at least a first queue level and a second queue level.

    摘要： A system for minimizing congestion in a communication system is disclosed. The system comprises at least one ingress system for providing data. The ingress system includes a first free queue and a first flow queue. The system also includes a first congestion adjustment module for receiving congestion indications from the free queue and the flow queue. The first congestion adjustment module generates end stores transmit probabilities and performs per packet flow control actions. The system further includes a switch fabric for receiving data from the ingress system and for providing a congestion indication to the ingress system. The system further includes at least one egress system for receiving the data from the switch fabric. The egress system includes a second free queue and a second flow queue. The system also includes a second congestion adjustment module for receiving congestion indications from the second free queue and the second flow queue. The second congestion adjustment module generates and stores transmit probabilities and performs per packet flow control actions. Finally, the system includes a scheduler for determining the order and timing of transmission of packets out the egress system and to another node or destination. A method and system in accordance with the present invention provides for a unified method and system for logical connection of congestion with the appropriate flow control responses. The method and system utilizes congestion indicators within the ingress system, egress system, and the switch fabric in conjunction with a coarse adjustment system and fine adjustment system within the ingress device and the egress device to intelligently manage the system.
