There and back again: reinventing UDP streaming with QUIC
summary
QUIC is now an IETF transport being finalized alongside HTTP/3, with 16+ implementations and live HTTP/3 deployments at Cloudflare; the talk claims lower latency, head‑of‑line mitigation, and extensibility. Demonstrations include an interop matrix showing feature coverage, a quiche prototype adding a Datagram frame, a nascent WebTransport API, drafts for RTP over QUIC, multicast proof‑of‑concept code, and a partial‑reliability proposal — many experiments work but specs and extensions remain unfinished.
