| Abstract: | Analyzing and estimating the cell loss probability in an ATM multiplexer is one of the most important problems concerning traffic control and resource management in an ATM based BISDN. Most of the present methods have some shortcomings in respect of efficiency and exactness. Considering the limitation of the discretised fluid flow technique, it is extended to be suitable to make queuing analysis of 2 state MMDP source passing through ATM multiplexer. The technique is also used to estimate the cell loss performance of an ATM multiplexer loaded with homogeneous On Off sources. Numerical calculation and simulation results indicate that the method presented is sufficiently accurate and computational efficient. |
