But, when you have a limited amount of participants in a room or 1 to 1 video call, you can use a different approach.
See, there is no server, all participants are connected to each other. How cool is that!
As always there are pros and cons of such a system, it’s called “Mesh” by the way.
Pros: You don’t need media streaming servers.
Cons: You can’t hold many users in such a room. It depends on the video quality and device power, so let’s say 6-8 users is a maximum.
Ok, so we have this Mesh approach and it works well for Telemedicine, for Education applications in small groups.
