A New Approach to Cell Loss Analysis for Long-Range Dependent Network Traffic

A new expression for cell/packet loss probability in an ATM and packet switched queue system with a finite buffer is presented. Cell and packet loss analysis is based on the new concept of a “buffer overflow cluster” and the overflow probability for a queue with an infinite buffer. This approach holds for a wide variety of long-range dependent traffic sources typical of wide-area networks, as well as Internet and other communication traffics. The method is verified by simulations of two longrange dependent traffic scenarios: fractional Gaussian noise and multifractal wavelet model traffic with a beta marginal distribution. key words: cell loss, buffer overflow, network QoS, traffic prediction, longrange dependent traffic, multifractal wavelet model
