Reducing bandwidth for testing

For testing purposes etc. I need 1) Ways to reduce bandwidth on a connection (each direction) 2) Simulate brok开发者_StackOverflow中文版en connection. 3) Measure bandwidth, perhaps see whats going through.

I am thinking of something like a proxy or perhaps something plugging into Apache/Tomcat

(Should look like a http URL/URI to the client)

Found this one for Windows using Fiddler http://www.logic-worx.com/index.php/tools-and-apps/fiddler-connection-simulator/

This "proxy" can simulate all of that for you and does a good job as well.. http://info.iet.unipi.it/~luigi/dummynet/

Commercial tools can be very expensive for this kind of testing so worth the effort setting up a dedicated linux box for this. I have not tried the windows version yet..
