Dummynet revisited

Dummynet is a widely used link emulator, developed long ago to run experiments in user-configurable network environments. Since its original design, Dummynet has been extended in various ways, and has become very popular in the research community due to its features and to the ability to emulate even moderately complex network setups on unmodified operating systems (FreeBSD, Mac OS X and now Linux as well). The goal of this paper is to present in detail the current features of Dummynet, compare it with other emulation solutions, and discuss what operating conditions should be considered and what kind of accuracy to expect when using an emulation system.
