Evaluation of the FreeBSD dummynet network performance simulation tool on a Pentium 4-based Ethernet Bridge

This technical report describes a simple procedure to estimate dummynet performance. Dummynet is a module installed on the bridge that will allow us to subject selected packets to delays, random loss or bandwidth limitation. The goal is to verify how precise is dummynet since in a future project we might use it as a traffic shaper for a network simulation. This report is mainly based on another report from A.L.Cricenti: 'Evaluation of a Pentium PC for use as an Ethernet Bridge'.
