Abstract

A method, a system and a base-station for automatically determining delays of data transmitted via Transmission Control Protocol (TCP) and inflating these delays in order to reduce jitter and improve TCP throughput in a communications network. A Dynamic Jitter Reduction (DJR) logic/utility operating within a communications node measures delays on a rolling basis in order to capture the delay profile. Based on the delay profile, the DJR utility determines a delay target. The DJR utility 'inflates'/augments future/expected delays toward the delay target by performing on one or more of the following: (a) using a delay based factor in the scheduler metric for TCP applications; (b) performing fine-tuning of link adaptation schemes; (c) delaying transmission of packets at the transmit or receive buffer; and (d) delaying transmission of a received TCP ACK signal from the media access control (MAC) sub-layer to TCP layer.
