MMPP-based HTTP traffic generation with multiple emulated sources

Abstract

In this article we propose a new tool, named Raw Packet Sender (RPS), for testing the performance of WWW servers. Our solution allows for testing with arbitrary number of source IP addresses although the tra#c originates from only one physical NIC. In order to better mimic the real life environment we implemented an HTTP session interarrival time generator based on Markov Modulated Poisson Process (MMPP), which can closely match auto-covariance and the marginal distribution of recorded web tra#c traces
