I'm looking for a (preferably) free software to install on a dual NIC box to shape badwidth and/or introduce packet loss, latency, etc.
Now I know dummynet and similar software but I need an API to control it. Maybe a simple RESTful http or SOAP based one. Preferably something more manageable than command line.
It may not be a production quality since I plan to use it for a demo/prototype.
