Hey,
I have done massive testing on our ervers to see how much bandwith
we can really handle.. The server them selfs work very well, we run 4
linux boxes for out streaming. Each on there own cable line who clame
10/2. MB
We use voice quality strems 24k mono streams.. We can get about
110-120 streams goign from the servers before they start deniing
access.. We decied to trhodle the main server at 80 clients and the
slaves at 100. and useing a balancing program i delveloped to force
the redirect before it get to the server. (I found some players did
not follow the slave chain reliable enough). So i wrote a routing
program that did a load balancing act o nll the servers.
How I ran the test was using a a http get to to streams and dumped
them to the bit bucket. And I monitored the bandwith from them the
server, the server report about 1.8MB xfer rate at the time the
cable/modem/router started to balk on us.
Honestly only way you can know the real bandwidth is to test it. I
found out a T1 that we were going to get was not really a T1 but a
fractal one, and when we cmplained they said they could not do
anyhitng about it so we droped them.
I have foudn the icecast server to be a solid server for audio
streaming. We currently dabbing into video streaming and the court is
still out of that..
