Abstract:
A method for obtaining optimum utilization of a shared transmission medium for multimedia traffic, complying with the customer QoS requirements for any type of the traffic sessions through the transmission medium whereby the maximum accepted losses of data packets and maximum accepted transmission delays are met, the method comprising:constructing a complete histogram for each type of a plurality of sessions, wherein each complete histogram comprises a plurality of regular histograms, each regular histogram being constructed by counting data units arrivals in a number of time intervals, the number of time intervals being different for each regular histogram; making a convolution of values from the complete histograms representing said sessions to estimate an aggregated histogram comprising the data units arrivals from the plurality of sessions; estimating the probability of loosing some data units of the whole sessions, and adjusting at least one of the bit rate reserved for the sessions, the packet loss rate PLR and the transmission delay.
