An upper bound for cell loss probability of bursty sources in broadband packet networks

An upper bound for the probability of cell loss of bursty sources in broadband integrated packet networks based on asynchronous transfer mode is discussed. A performance model is developed to obtain this upper bound for traffic sources admitted into the system in connection-oriented services. It is possible to evaluate the required bandwidth for a desired cell loss rate, and provide procedures for call admission and proactive congestion control at the access nodes of the network using this upper bound. A simulation model and results for a number of cases are given and the tightness of this bound is verified, especially for moderate cell loss rates
