DYNAMIC TRAFFIC COMPETITION IN ATM NETWORKS

Summary: In todays heterogenous multimedia ATM networks, there are multiple network managers, multiple trac types and every user exploits the network resources according to availability, performance and cost. Thus, there are many decision-makers competing each other, and each one tries to achieve the best for his own good. In order a decision-maker to take the best decisions, he should have accurate in-formation about the network state. However, in todays high speed multimedia ATM networks, the network state changes very fast and abruptly. Thus, a dynamic net-work model should be considered in the analysis and optimization of these high speed networks. In this paper, we rst model the dynamics of ATM networks using both the virtual call and the cell processes in a two-level dynamic model. Then we provide a dynamic game framework for the resource sharing problems in ATM networks with competing trac. Finally, we formulate the dynamic game problem both as a Nonlinear Comple-mentarity Problem (NCP) and as a Variational Inequality Problem (VIP). 1
