This thesis is concerned with an outline survey on the modern aspects of asynchronous transmission mode (ATM) telecommunication; also considered are certain specific issues such as the performance characteristics of ATM-based telecommunication networks under fluctuating workloads. Estimation of the stochasticity of the jitter associated with the cell-delay arising out of buffering within the network as well as due to signal-to-noise considerations which induce bit-errors and eventually lead to cell-losses manifesting as delay(s) in the cells being transmitted, is also addressed as a part of this thesis efforts. Relevant theoretical models are proposed, algorithms are developed and simulations are done on the above considerations. Based on these efforts, inferential conclusions are drawn and discussed. Scope for future research and developments towards engineering design of softwares suitable for practical applications by ATM networking planners and traffic forecasters is indicated. Merits and shortcomings of the models are proposed and algorithmic approaches pursued in the present study are also specified with relevant discussions.
