No, what you suggest is bandwidth limiting. It would not solve the large 
bursts Marian Durkovic is talking about.
It would just chop of bandwidth exceeding traffic or delay udp packets. 
Both are evil.

Delaying packets of video stream will make the video/sound very choppy 
at the receivers end. In other words it will kill the real time 
behaviour of a video stream.

A real bandwidth limiter will throw away the packets that exceeds the 
bandwidth limitation. This will also result in poor video and audio 
quality. It might even crash the video decoder.
