Abstract:
1. A method of incrementing a receiver-initiated sending rate of data packets transmitted from a sender over a network to a receiver using a Transport Control Protocol (TCP), the method comprising the steps of: sending acknowledgments at regular time intervals for received data packets from the receiver to the sender, said acknowledgments containing an advertised window indicating the allowed sending bit rate; storing the acknowledgments in a queue before transmission to the sender; sending an acknowledgment for a portion of a segment to the sender when there are less than a predetermined number of acknowledgments in the queue at the next regular time interval; and increasing the advertised window by a maximum of one segment size per acknowledgment, wherein: the acknowledgment for the portion of the segment increases its advertised window by one segment, whereas the acknowledgments for the remainder or for whole segments do not increase the advertised window, both acknowledgments allowing the triggering of one next data packet.
