Head Meets Desk

Greetings

I am currently running FMIS on a computer running the following specs:

Processor: Intel Core 2 Quad Q8200 @ 2.33GHz

Memory: 8GB

OS: Windows 7 Ultimate 64bit

Comcast is the ISP of choice with the Business Class package and the latest bandwidth speed test results are:

Download Speed: 2761 kbps (345.1 KB/sec transfer rate)
Upload Speed: 1242 kbps (155.3 KB/sec transfer rate

I keep running into a problem where the broadcasted content will be available to view without any skips or lags when a few people are on, however, once thousands upon thousands start tuning in, everyone complains about it skipping so bad it's unwatchable. The selected bitrate for the Adobe Flash Media Encoder 3.1 is 100kbps for video and 22kbps for audio, thus totalling 122kbps.

Any recommendations? It appears as though something just isn't handling a mass amount of end-users connecting.

    It's due to insuficcient bandwidth at the server side. you have roughly 1.2Mbps of available upstream bandwidth. With your 122kbps stream, you can effectively serve about 10 viewers before your internet connection bottlenecks (each viewer consumes 122kbps).

    The solution here is to move your FMS to a proper datacenter with better networking capacity. You mentioned thousands of viewers... if we assume even one thousand viewers, your 122kbps stream will require about 120Mbps of bandwdith.
