WebRTC (Web Real-Time Communication)

An open framework that enables real-time audio, video, and data communication directly between browsers without plugins. WebRTC uses ICE (Interactive Connectivity Establishment) for NAT traversal, DTLS for encryption, and SRTP for media transport. The signaling mechanism (exchanging session descriptions) is not specified by WebRTC and typically uses WebSocket or HTTP. WebRTC powers video calls, screen sharing, and peer-to-peer file transfer.
