(English Abstract) |
Recently, there have been proposed a number of service architectures and mechanisms to meet the demand for the quality of service. The proportional Differentiation Services(PDS) architecture has been an effort to quantify the differentiation between classes of traffic and to enforce that the ratios of delays or loss rates of successive priority classes be roughly constant. In this paper, we investigate the possibility of providing proportional loss differentiation and demonstrates, through numerical analysis and simulation, that the overlapped random early detection (RED), a slightly modified version of the original RED, achieves proportional loss differentiation (PLD) among different classes of traffic. The numerical analysis of overlapped RED is presented by deriving the drop probability equations using the M/M/1/K queueing model. Guidance on methods of setting the appropriate drop probabilities are verified using an ns-2 network simulation. The simulation result shows that the proposed approach is desirable for adjusting the appropriate PLD among different classes and consists with numerical analysis.
