WebTransport
WebTransport is a web platform API and protocol designed to enable low-latency client–server communication by leveraging QUIC and HTTP/3. It provides a session-based transport over a single connection that can carry multiple logical data channels between a client and a server, reducing the overhead of repeatedly establishing new connections. WebTransport exposes different data paths, including reliable, ordered bidirectional streams for stream-oriented data and datagrams for message-based communication. It also supports unidirectional streams to send data in one direction. The traffic on a WebTransport session is multiplexed, allowing many streams and datagrams to coexist efficiently.
WebTransport sessions begin with an HTTP/3 handshake that establishes a QUIC connection and negotiates a WebTransport
Use cases for WebTransport include real-time multiplayer gaming, live collaboration tools, streaming telemetry, and other latency-sensitive
Security and privacy are built on the underlying TLS 1.3 and QUIC security model, with the same-origin
