Modeling Internet Traffic: Performance Limits

Traffic modeling is an important tool for performance evaluation of networks. Over the last decade traffic characterization studies revealed the presence of different types of correlations in Internet traffic. In this paper we present traffic modeling methodology by aggregates of bytes using the M/G/infin process for capturing traffic correlations. We use recent traffic traces to construct M/G/infin traffic models, and we evaluate the generated traffic both statistically and by simulation in network environment. We show limitations of bytes aggregates models, and we conclude by propositions to obtain more accurate models
