Some Basic Math:

With a 32k audio stream, you would need in theory:

4 x 32kbps = 128kbps of up bandwidth (to the server)
100 * 32kbps = 3200kbps of down (or 3.1mbps) (from the server)

How assuming that the 1.5mbps was your down (from the server) bandwidth) and your 512 was your up (to the server) you'd be short on the down.

That said, with 32kbps being on the rather low end of audio quality, you would have a tough time serving 100+ streams from the box. I also suggest wiggle room (always good to have a little excess)

Dear Red5:
I would like to know how to figure out the bandwidth I would need on a conference project with the following:


100+ users (audio only) - A max. of 4 users will be broadcasting at any one time. The others will not be streaming audio except when one of the streaming ones is quiet and that user is enabled by the admin.

1 MP3 stream (for recording)

I have 1.5 Mbps/ 512 Kbps connection. Could I do something like this with that connection? If so, could someone point me in the right direction for finding out how to code this? (I am only experienced in PHP and the like. I am having trouble learning how to do this in Java and Flash.)

Thank you,
Robert Fleming
