What is WebRTC BUNDLE?

The BUNDLE mechanism (RFC 8843) multiplexes multiple media tracks (e.g. audio and video) over a single 5-tuple (IP, port, and transport protocol), conserving socket pairs and simplifying NAT traversal.

What are ICE candidate types?

host candidates represent local network adapters, srflx (server reflexive) candidates are discovered via STUN servers to bypass NATs, and relay candidates route traffic through TURN servers when direct peer-to-peer connectivity is blocked.

Frequently Asked Questions

What is the DTLS fingerprint attribute?

The a=fingerprint:sha-256 ... line ensures mutual authentication between WebRTC endpoints during the DTLS-SRTP handshake, protecting calls from man-in-the-middle attacks.

Is my SDP offer or network IP sent anywhere?

No. Parsing and inspection are performed 100% inside your browser memory using local regular expressions and line parsers.
