Do anybody know what kind of system architecture is behind Websites like tinychat, omegle, cam4, chatroulette? And how much bandwith is needed per connection?
If I'm not wrong they use some video streaming Server like Flash Media Server, Wowza Media Server, Red5, Erlyvideo but this would eat for 20'000 users around 1 Gb/s bandwith? Or do they use some software who is wroking peer2peer? I found some kind of such Software but they all requires some UDP ports to be opened.
Do anybody know how much users 1 server instance with some of the above server software can handle?
Im happy for any background information.
