Is there any tool that works like router and transforms reliable network traffic into not very reliable? I am looking for features like:

  • Connection drops
  • Split packets
  • Lag

Problem is that I have an embedded device and I need to stress my ETH drivers and application.

WANem

Maybe give WANem a try, I've used it myself and found it extremely helpful for such purposes.

WANem is a Wide Area Network Emulator, meant to provide a real experience of a Wide Area Network/Internet, during application development / testing over a LAN environment.

WANem thus allows the application development team to setup a transparent application gateway which can be used to simulate WAN characteristics like Network delay, Packet loss, Packet corruption, Disconnections, Packet re-ordering, Jitter, etc.

I had 2 network cards in low end machine and I wanted that this should work like router, but I ended like setting this up like switch (which is even better) So, I had problems setting up bridge (had no idea about that technology), and I found this link reloadin10.wordpress.com/2008/08/22/wanem-bridging-interfaces where I just changed bridge IP on static IP in my network, and gw on my network gw (getway). I have also found and tested wanulator.de and I can tell that it is simpler to use , but has limited capabilities and does not support random disconnection. –  ralu Apr 20 '11 at 20:01
