Abstract: A per-flow queuing method and apparatus for IP networks carrying traffic from feedback controlled TCP connections enables flow of information packets from one or more sources to a destination through a link and comprises a buffer of predetermined size partitioned into a plurality of queues, each queue being allocated an occupancy bi for receiving and temporarily storing packets of information; a scheduler for removing packets from each buffer according to a predetermined rate and transmitting the packets over a network; and a control device for determining availablilty of queues in the buffer capable of receiving the packet and inputting the packet into a queue if the queue is available, the control device further selecting a queue and releasing a packet from the selected queue to accommodate input of the received packet when the queue is not available. Increased fairness and packet throughput through the link is achieved when the queue for dropping a packet is selected in accordance with a longest queue first or random drop scheme and, when a drop from front strategy for ACK packets is employed.
