Dummynet is a tool that has been a BSD staple for a long time now.
Originally it was developed to allow for simulation of various network
configurations and scenarios. With dummynet you can do fun things like
simulate a ASDL line that was suffering 70% packet loss, or take a trip back
in time to a 300bps modem connection. (I used a 300 baud modem from 1984 to
1992!) dummynet is still often used for tasks like this, but sysadmins are
crafty people and had the idea to commandeer these network simulation tools
into a way to control the packets flowing through a server. You can do this
for all packets or you can be selective, guaranteeing one protocol or
service receives a greater --or lesser-- share of the managed bandwidth than
the others. This is called traffic shaping.
