A method and apparatus which provides a general solution technique for the integration of traffic measurement and queueing analysis. The frequency-domain approach is used to combine the advanced techniques in two areas: signal processing and queueing analysis. The tool comprises three basic components: traffic measurement, statistical matching and queueing analysis. In the traffic measurement component, standard signal processing techniques are used to obtain the steady-state and second-order statistics of a traffic stream. In the statistical matching component, new techniques are used for the construction of a special class of Markov chain modulated rate processes, the so-called circulant modulated rate process, that can statistically match with each given traffic stream (or superposition of different traffic streams). In the queueing analysis component, both steady state and time dependent solutions of buffer size, link capacity, loss rate, overload control and queuing behavior are obtained by the generalized Folding-algorithm. Comprehensive numerical examples show the great potential of the present invention to solve measurement-based traffic management issues.
