hxbt STREAMS Module
From an announcement on the OpenSolaris Networking community site
Hxbt is a Stream module/driver which emulates a WAN environment. It captures packets from IP and manipulates the packets according to the WAN setup. There are five parameters to control the environment. They are network propagation delay, bandwidth, drop rate, reordering, and corruption. Hxbt acts like a "pipe" between two hosts. And the pipe is the emulated WAN.
