Abstract

This article presents a discrete event simulator, called Queen's University IP Simulator-II, which can be used for the design and performance evaluation of Diffserv-based networks. The simulator implements both the expedited and the assured forwarding per-hop forwarding behaviors in Diffserv networks, sharing many features of the IETF proposals. By setting up a network model with variable parameters, simulation can be carried out to observe the Diffserv behavior. Some performance evaluations of both forwarding mechanisms are provided as examples.
