Hello, 

At the same time there are 50 people in the video case, the server needs how much bandwidth?

Thank！

Is there anyone who can answer it?。。。。。。

Bandwidth consumption depends on your resolution/bitrate and usage model (conference or broadcasting).

VGA resolution,conference model， Is the 3.2 version of the，How much bandwidth do you want?

VGA input is controlled by your client side through SDK interface, for MCU it's downlink bandwidth consumption, which is your individual VGA publish input bandwidth x 50. If everyone subscribe mix VGA stream, the output is 800Kbps by default, so it's uplink bandwidth for MCU, which is 800Kbps x 50.

Hi Lei,

can we calculate bandwidth as below is that correct

Server Bandwidth:

Forwarding VC Mode:

No.of Publishers x 0.4 Mbps(VGA) or 1Mb ( HD ) x (Total no.of users - 1) = Total Bandwidth

Mixing VC mode:

No.of Publishers x 800kbps(VGA) or 1 MB(HD) = Total bandwidth


Client Bandwidth:

Forward Mode:

0.4 Mbps(VGA) or 1Mb ( HD ) x (Total no.of users - 1) = Total Bandwidth

Mixing Mode:

0.4 Mbps(VGA) or 1Mb ( HD ) 
 

Thanks

Generally that's correct. Also please be aware that both client and server side bandwidths can be separated to down link and up link one.
