Overview


This work was done as a home work for the Simulation and Performance Evaluation course given by Pr. Farouk Kammoun at the National College for Computer Sciences in Sep 1997-Jan 1998. We spent a couple of weeks working on it. The PostScript version is particularily large because by the time of the writing we didn't know how to save a GNUplot figure to a PostScript file, so we used xwd instead! The whole source code with some sample output and this document in PostScript format are available for download. You can also grab just the report either in compressed PostScript or in PDF format.

Abstract

This paper presents the results of a multimedia traffic simulation at a router. The policies simulated are First In First Out (FIFO) and Earliest Packet Discard (EPD). We give also the implementation details of our simulator on the Linux operating system. Since the aim of this work is to have some deep insight into the workings of simulators and not the simulations themselves, we suggest that you focus on the design issues of the simulator more than the simulation results.
