Hi Siphiwe,

I don't know if vlc is possible to adapt the bitrate while streaming.
Maybe you have to restart the stream with the adjusted bitrate parameters
(please correct me if i'm wrong).

But maybe you should take a look at the RTCP protocol described in RFC3550.
It is mainly used to determine network congestion by sending reports from
client to server (and vice versa) about the bytes sent/received etc.
Usually RTCP is used for adaptive bandwith switching, so maybe you don't
have to implement everything from scratch and reuse existing standards.
Maybe you are interested in implenting this functionality (RTCP on 
serverside and
adaptive bandwith switching) in vlc and contribute to opensource?

Best regards,
Torben
