Packet Tracing in Simulation Environments

Abstract

This master thesis is a part of my Master's degree at the University of Oslo. The thesis has been written at Simula Research Laboratory (SRL), where my supervisors Sven-Arne Reinemo and Tor Skeie work. Another advantage of doing my work at SRL is the availability of a small computer cluster on which I could run the tests needed for my thesis. The goal of my master thesis is providing the Infiniband simulation in Omnet++ with means to simulate real-world network traffic. The master thesis consists of two main parts. The first part is about integrating two simulators – the Infiniband simulation in Omnet++ with LogGOPSim. In the design chapter (Chapter 4) I describe the implementation of the integration, its functionality, the problems experienced and solved during implementation and the integration's effectiveness. In the second part of the thesis, the evaluation chapter (Chapter 5), I describe the process of testing how the integration works and the results of calibrating the input for the simulation. During this explanation I use several simple examples which are supposed to provide clarity in what really goes on during the simulation. The explanations of the central technologies and terms of this thesis are presented in the two background chapters – Chapter 2 gives a relatively shallow description of the less central terms, while Chapter 3 gives an in depth description of what is most important.
