A METHOD AND APPARATUS FOR ESTIMATING TRAFFIC IN AN ASYNCHRONOUS TELECOMMUNICATIONS NETWORK

摘要

A method and apparatus for estimating traffic in an asynchronous telecommunications network, which can provide estimates in real-time and can be adapted to suit the speed of variations in the cell traffic. Synchronous iterative loops accumulate detected cell arrivals and inter-arrival times, with the accumulation of previous values being modified by a response factor. A ratio of the outputs from the synchronous loops can be calculated asynchronously to provide an estimate of cell traffic. The output from two estimators utilising different response factors can be latched according to detected changes in cell traffic so as to provide either a smooth but accurate response, responding slowly to variations in traffic, or a fast but noisy response.
