摘要
In a peer-to-peer asymmetric communication environment, an adaptive upload Data Rate Control element—called Adaptive-DRC—is used to detect increase in data return-trip time (RTT) caused by the congestion associated with the uploading of data in an uplink which in turn impacts on downloading data on an associated downlink, namely a downlink sharing resources with the uplink. Using Adaptive-DRC, the congestion is detected and thereupon adjustments to are made to allow continued communication. Adaptive-DRC comprises: (i) RTT estimation; (ii) detection of the onset of congestion, herein pre-congestion detection; and (iii) adaptation of the upload data rate limit. Two specific embodiments are contemplated, namely two versions of Adaptive-DRC wherein the difference lies in the upload data rate limit adaptation technique.
