A virtual integrated network emulator on xen (viNex)

Abstract

Network research experiments have traditionally been conducted in emulated or simulated environments. Emulators are frequently deployed on physical networks. Network simulators provide a self-contained and simple environment that can be hosted on one host. Simulators provide a synthetic environment that is only an approximation of the real world and therefore the results might not be a true re ection of reality. Recent progress in virtualisation technologies enable the deployment of multiple interconnected, virtual hosts on one machine. Virtual hosts run real network protocol stacks and therefore provide an emulated environment on a single host. The rst objective of this dissertation is to build a network emulator (viNEX) using a virtualisation platform (XEN). The second objective is to evaluate whether viNEX can be used to conduct some network research experiments. Thirdly, some limitations of this approach are identifiedComputingM. Sc. (Computer Science
