If not, you really should be looking at multicast, which would give you only 20 streams on the wire. > When I only want to send voice I have a data rate for one channel about > 64kb; for 19*20channels=380 channels; if I send each 3 ms a packet the > data rate will go up to 92,1 Mbit/s (include the Ehternet-, IP-,UDP-, RTP- > Header and 5 per cent RTCP- Traffic). 3 ms sounds pretty over the top. Do you really need that? The standard for realtime audio streaming is usually 20ms (ie. 50Hz), which would give you around 25 Mbit/s for 380 streams and only 1.3 Mbit/s for 20 multicast streams. -- CJ van den Berg mailto:cj at vdbonline.com xmpp:cj at vdbonline.com -------------- next part -------------- A non-text attachment was scrubbed...
