Bandwidth Problem! Stream blocks when are more simutaneous users on server!

Question

Hello,I'm usig Adobe Flash Media Streaming Server 3.0.1, it works fine, no major problems, when the internet between Media Encoder and Server stops, some times the stream doesn't start automatically.I have a problem with users(viewers) trying to connect to server. The server is connected to fiber optic internet at 100mbps and the stream is made in 500kbps with media encoder 2.5.When are 40-50 simultaneous viewers works fine, but when enter more viewers, for example, 200 simultaneous, nobody cam receive the stream good, it works frame by frame or flash player display "buffering", work 3 seconds and buffer 5 sec,and so on.HOW I CAN RESOLVE THIS PROBLEM??? I heard it is possible to connect milions of users simultaneous, how can i do that.I need more servers to connect each to each other? Could you send me a diagram how to do that???I need to increase the ram memory from server?( i have P4 dual core 3.0 Ghz, 6 Gb ram 800Mhz).I'm waiting for your answers!Thank you,Florin

If you're serving 500kbps video over a 100Mbps uplink, it makes sense that the server will choke when you try to serve 200 clients. Although your NIC can support 100Mbps, you need to maintain some unused overhead or you risk server lock.

The solution... either lower your video bitrate, or upgrade your uplink to gigabit. On your note scaling aross multiple servers to handle large audiences... the following should get you started:

Note that the guide linked in the article assumes you're using FMS 3.5
