Abstract:
A method for estimating source-destination traffic for a packet-switched communications network, wherein the network includes a plurality of nodes interconnected by a plurality of links, and wherein the network includes a plurality of source-destination node pairs, wherein each source-destination pair is assigned at least one traffic path between the source node of the pair and the destination node of the pair, each traffic path including at least one link, the method comprising the steps of:obtaining a measurement of traffic arriving on each of the plurality of links; obtaining a measurement of traffic overflowing from each of the plurality of links; determining a relationship between the measurement of traffic arriving on each of the plurality of links and a traffic rate for each source-destination pair based on the assignment of traffic paths to the plurality of source-destination pairs and the measurements of traffic arriving on and overflowing from each of the plurality of links; and determining an estimate of the traffic rate for each of the plurality of source-destination pairs based on the measurement of traffic arriving on each of the plurality of links and the determined relationship between the measurement of traffic arriving on each of the plurality of links and the traffic rate for each source-destination pair.
