This repository works as test for learning WebRTC. Also taking notes and describe how does it work.
To connect a clientA with clientB using WebRTC the only necessary action is that each client know the direction of the other client, this action is usually done by a server but it also may be done sending this info by other message service.
As usually, a middle server send the info to communicate between clients to start the communication between them. The protocol used to sen others info is SDP.
The info sended is the ip address and the port where is listening of each client.
To send info between clients, they will use the UDP protocol, insetad of TCP protocol due its speed when sending packages
