An Integrated Block-Oriented Simulation Model for Estimating Cell Loss Rate in ATM Networks

It has always been desired to simulate a network so as to be able to study its different performance characteristics under various operating conditions. This work presents an integrated MATLAB ® based simulation model capable of evaluating cell loss rate which is an important QoS parameter in multimedia networks such as ATM networks. The integrated model combines both the simulation and analytical model in the same environment. The analytical model is fed directly from results obtained from the simulation model; the advantage of this arrangement is that the statistics generated during simulation gives the exact description of cells activities at the transmission buffer. The variation of cell loss rate with buffer capacity for a single source at a given bandwidth was obtained from this model within reasonable simulation time. (
