  2. When studying the network performance, flow control and resource provisioning of communication networks, traffic model plays a very important role. the recent studies show that the date network traffic is self - similar, so the markovian model, which describes telephone networks accurately, is not suitable for date networks. the self - similarity of the network traffic has severe impact on flow control and queuing analysis in date networks, therefore it has received significant attention. in this paper, g m 1 queuing model is used to analyze the queuing performance of generic variable length packet networks for the first time. the self - similar traffic is generated by multiplexing a large set of independent pareto heavy - tailed interarrival on off sources. the simulation results show that the heavy - tailed traffic results in queuing performance deterioration for variable length packet networks, which is in accordance with the analytical results for atm switches
