Abstract
Real time communications over a network are adjusted to improve the quality of service (QoS) under incipient congestion conditions. The system detects incipient network congestion and feeds back information regarding the incipient congestion back to the transmitter. Based on this information, the transmission rate is altered appropriately using a control algorithm, which computes the altered transmission rate based on a weight parameter, a gain parameter, and information from a congestion report. The altered transmission rate improves the transmitter's use of the available bandwidth to maintain an acceptable QoS at the receiver.
