Paper Abstract

Cell Loss Ratio estimation is a crucial technology in call admission control and traffic engineering in ATM networks. Cell arrival process and analytical approach had been investigated in recent years. However, an effective and practicable CLR estimator is still a challenge. Based on the analysis of cell loss problem, an improved simple traffic model and a new algorithm are presented in this paper, to estimate CLR of ATM network multiplexed with heterogenous traffic classes services rapidly. Traffic model is constructed with standard parameters, so it is easy to use in practical situations. The new algorithm runs quickly enough to respond the call real-time. Simulation results show that accuracy, complexity and robustness of algorithm are ideal to be utilized in real network.
