By carefully selecting and implementing the right service, you can ensure seamless peer-to-peer connectivity that works effectively across different network configurations. WebRTC doesn’t use a client/server model, it establishes peer-to-peer (P2P) connections. Feb 16, 2022 · STUN is a protocol that helps Internet endpoints dealing with NAT (Network Address Translation), a typical condition for hosts belonging to a private network and requiring to be accessed from another network, like the public Internet. It also ICE, STUN, and TURN are the unsung heroes of WebRTC, working behind the scenes to make real-time communication possible. Signaling is not part of the WebRTC standard and thus needs to be handled separately if you are building the application yourself rather than using a commercial platform (more on this later!) If you are a WebRTC (Web Real-Time Communication) enables peer-to-peer connections for real-time audio, video, and data sharing.
