In short

trickle is a portable lightweight userspace bandwidth shaper. It can run in collaborative mode (together with trickled) or in stand alone mode.

trickle works by taking advantage of the unix loader preloading. Essentially it provides, to the application, a new version of the functionality that is required to send and receive data through sockets. It then limits traffic based on delaying the sending and receiving of data over a socket. trickle runs entirely in userspace and does not require root privileges.

trickle is developed on OpenBSD/i386 and is tested on
OpenBSD/SPARC/SPARC64/MacPPC, Sun Solaris/SPARC/SPARC64, NetBSD/Alpha, FreeBSD/i386 and Linux/i386.

trickle is licensed under a BSD license.
