Dummynet: The Better Way to Build FreeBSD Networks

Dummynet is the FreeBSD traffic shaper, packet scheduler, and network emulator. Dummynet allows you to emulate a whole set of network environments in a straight forward way, it has the ability to model delay, packet loss, and can act as a traffic shaper and policer. Dummynet is roughly equivalent to netem in Linux, but we have found that dummynet is easier to integrate and provides much more consistent results.
