Performance Analysis and Evaluation for Multi-Traffic Networks Using Priority Based Controlled Available Bit Rates

In this paper, we consider a multi-traffic network system with a transmission link shared by Available Bit Rate(ABR) application for non-real time traffic and Variable Bit Rate(VBR) application for real time traffic. It is assumed that the VBR traffic has a higher transmission priority than ABR traffic. We propose a new feedback control method to control the flow of the ABR traffic. In this method, the ABR source has multiple states and the number of cells transmitted by the ABR source is controlled by the feedback on the congestion state of the buffer. By using the Markov chain method, we establish a tractable analytical model for the system. We give some iterative formulas for calculating the transition probabilities. Then, based on the analysis, we calculate the cell loss probability and the utilization of the network system. The impact of several parameters on the system performance is presented through some simulation results.The original publication is available at JAIST Press http://www.jaist.ac.jp/library/jaist-press/index.htmlIFSR 2005 : Proceedings of the First World Congress of the International Federation for Systems Research : The New Roles of Systems Sciences For a Knowledge-based Society : Nov. 14-17, 2026, Kobe, JapanSymposium 3, Session 1 : Intelligent Information Technology and Applications Men and Computin
