Method of obtaining optimum use of a shared transmission medium for multimedia traffic

摘要

A method for obtaining optimum utilisation of a shared transmission medium for multimedia traffic, complying with the customer Quality of Service (QoS) requirements of the traffic sessions through the transmission medium whereby the maximum accepted looses of data packets and maximum accepted transmission delays are met, the method comprising constructing an histogram containing the arrivals of data units for each type of a plurality of sessions, the histogram representing the arrivals of data units per a predetermined interval of time; making a convolution of the values from the histograms representing said sessions to estimate an aggregated histogram comprising the arrivals from the plurality of sessions; estimating the probability of loosing some data unit of the whole sessions, and adjusting at least one of the bit rate and transmission delay to get the optimum transmission media utilisation. <IMAGE>
