摘要
A congestion control mechanism is presented, aimed at in creasing performances for multimedia traffic in "best effort" networks. A source-destination point-to-point video communication is investigated. The control algorithm dynamically varies the encoder configuration on the base of some feedback information from the destination. The selection of the proper configuration is performed by a control block called "smart coder" which, after receiving the feedback information, can change the transmission fate to optimize the level of Quality of Service (QoS) perceived by the user for a certain network status. The change of the transmission rate is performed by acting on coding parameters as the type of video coder, the spatial resolution, the frame rate and so on, formally defined in the paper. Feedback information is based on the measure of the average rate of the lost packets, but since this measure cannot give information about underload condition, a specifically designed probing mechanism, based on the introduction of a redundancy in the video flow, is used. A relevant part of the paper is dedicated to the analysis of the results: the efficiency of the control scheme is tested in a local environment based on the Ethernet protocol.
