Traffic analysis in large-scale high-speed integrated networks: validation of nodal decomposition approach
W.C.S. Lau, S.-q. Li · 2002
The conditions under which nodal decomposition can be applied for networkwide, multimedia traffic analysis are determined. Through extensive simulation studies of individual departure source characteristics and intersource cross-correlation at the output side of a network node, the nodal decomposition approach is validated for large-scale high-speed, integrated networks. Both homogeneous and heterogeneous traffic environments in which individual sources are modeled as various two-state/multiple-state Markov-modulated processes are considered. By applying the validated nodal decomposition approach, the problem of analyzing the performance of a multimedia network as a whole becomes tractable. Each ATM node is modeled by a queue with infinite buffers and a deterministic server.>
