Analysis and Modeling of Traffic in Modern Data Communication Networks

In performance analysis and design of communication netword modeling data tra c is important. With introduction of new applications, the characteristics of the data tra c changes. We present a brief review the di erent models of data tra c and how they have evolved. We present results of data tra c analysis and simulated tra c, which demonstrates that the packet train model ts the tra c at source destination level and long-memory (selfsimilar) model ts the tra c at the aggregate level.
