hi, everyone Plz, help me solve this tricky problem, making me suffering for almost one week.

How to make streaming video suffering packet loss?

Switch: Pica8 3290

Computer: core i7 2600, 8GB

OS(sever&host): Ubuntu 14.04

Link: 100Mps

Streaming video : VLC with RTP Streming(1080P、4K)

I've tried "iperf", "iperf3" and "Packeth" to generate UDP packets. However, these 3 sofwares seem to measure the residual capacity of the link first and then send the amount of the packets fit the capacity.

E.g.: (No Video streaming) iperf send almost 100Mps (With video streaming) iperf only send almost 70Mbps Thus, these packet generator won't help me to make the streaming video suffering serious loss. (What I want is make huge traffic and make the streaming suffering terrible loss and delay)

So, how can I create "congestion" and make the video streaming packets loss ?

Truly appreciate your help!!

If your source or destination is on linux you can try: "tc" or "tc-ng" . You can create delay or packet loss. It's just little complicated to understand. But just google it and you will find answer....

Thanks for the reply. So, what u mean is that Linux limit packet generator(low priority) and the media streaming has the higher priority ? (but, i didn't do any modifications before Linux won't cheat all the traffic the same?)

btw, i used individual computers, one as host(receiver), one as packet generator to test if the large traffic generated by iperf make the streaming packet loss.

however, the outcomes didn't look so....
