An Empirical Workload Model for Driving Wide-Area TCP/IP Network Simulations

چکیده
Abstract We present an artificial workload model of wide-area internetwork traffic. The model can be used to drive simulation experiments of communication protocols and flow and congestion control experiments. The model is based on analysis of wide-area TCP/IP traffic collected from one industrial and two academic networks. The artificial workload model uses both detailed knowledge and measured characteristics of the user application programs responsible for the traffic. Observations drawn from our measurements contradict some commonly held beliefs regarding wide-area TCP/IP network traffic. The simulation techniques presented here will be useful in studying congestion control, routing algorithms, and other resource management schemes, for existing and future networks.

متن کاملPerformance Impacts of Multi-Scaling in Wide-Area TCP/IP Traffic
Recent measurement and simulation studies have revealed that wide area network traffic has complex statistical—possibly multifractal—characteristics on short timescales, and is self-similar on long timescales. In this paper, using measured TCP traces and queueing simulations, we show that the fine timescale features can affect performance substantially at low and intermediate utilizations, whil...
