Information
56k Dialup Video for Web server:
Creates video 56 Kbps modem ASF content appropriate for streaming from a Web server.
This setting uses a single bit-rate which is necessary when hosting ASF files for HTTP
streaming on a server not using Windows Media Services.
56k Dialup Modem Video:
Creates video ASF content for clients connecting with 56 Kbps dial-up modems.
This template has multiple bit rate support enabled and therefore the additional video
data creates a total live distribution bandwidth requirement of 52 Kbps.
Dialup Modems - ISDN Multiple Bit rate Video:
Creates one ASF stream or file for multiple target audiences. Use this setting to encode
multiple bandwidths that support client connections over dial-up modems and single channel
ISDN using speeds between 28.8 Kbps and 56 Kbps. This MBR stream contains target bit-rates
of 22, 29, 34, 37, and 57 Kbps and has a total live distribution bandwidth requirement of 150 Kbps.
Intranet High Speed LAN Multiple bit rate Video:
Creates one ASF stream or file for multiple target audiences. Use this setting to encode
multiple bandwidths that support client connections ranging from dial-up modems to high-speed
corporate Internet connections. This MBR stream contains target bit-rates of 150, 300, 500,
and 700 Kbps and has a total live bandwidth distribution requirement of 1637 Kbps.
Bandwidth
The most difficult part is to accurately estimate the number of concurrent users who will connect
to your content. More often than not, people overestimate the number of concurrent users. The most
successful events on the Web have had tens of thousands of concurrent users, but the vast majority
are wildly successful with a hundred concurrent connections.
Calculating the total bandwidth required is easier:
Total for each bandwidth = number of concurrent connections at a given bandwidth * the given bandwidth
Total bandwidth required = sum of total for each bandwidth
(25*28,800 bps)+(25*56,000 bps) = 720,000 bps + 1,400,000 bps = 2,120,000 bps or 2.12 Mbps
Now that you know how much bandwidth you will need, you will need to make sure that you have enough "pipe"
to accommodate those users:
•T-1 line = 1.5 Mbps, or approximately 50 concurrent 28.8-Kbps streams
•T-3 or DS-3 = 45 Mbps, or approximately 1500 concurrent 28.8-Kbps streams
So in the preceding example, where we need 2.12 Mbps in bandwidth, we would need to have two T-1 lines in
place when the content goes live.
