WebRTC Data Channels vs WebSockets: P2P, SCTP & Configurable Reliability

12 questions

When real-time delivery goes peer-to-peer: how WebRTC data channels differ from WebSockets — SCTP-over-DTLS-over-UDP transport, configurable reliability and ordering, signaling (often carried over a WebSocket), NAT traversal with STUN/TURN, and mandatory encryption. The reliability modes are verified in Node.
