Thanks Sebastian, but I have to provide a practicable scenario, anticipating The demand. In the primary use each room will have only 2 participants with audio, video , whiteboard and chat. The video can be 240x180 (40 Kb/s) or audio + video = 70Kb/s. With this information I calculate traffic sent into the server: 2 * 70Kb/s = 140Kb/s and server traffic sent out: 2 * (2-1) * 70Kb/s = 140Kb/s (I only need it). So every room of this example uses only 140K/ s of bandwidth server.
Making a simple division it says, in theory, than with a server bandwidth of 100Mb/s I can have up to 726 people simultaneously connected in 363 rooms (2 people per room in this example). This forecast shall is correct?
