"WebTransport seeks to provide, among other things, lower latency and transparent network switching for key use cases such as high-frequency financial data streaming, cloud gaming, live streaming, and collaborative editing."
"WebSockets rely on TCP, which is built for reliable, ordered data delivery. What may be the right choice for a file download may be more problematic for modern use cases where high-speed interaction outweighs reliability."
"WebTransport solves these architectural flaws by leveraging HTTP/3 and the QUIC protocol. Because QUIC runs on top of UDP, WebTransport supports both reliable byte streams and unreliable datagrams."
WebTransport is a new protocol designed to improve upon WebSockets by addressing performance issues such as head-of-line blocking. It utilizes HTTP/3 and the QUIC protocol, allowing for both reliable byte streams and unreliable datagrams. This is particularly beneficial for applications requiring low latency, such as cloud gaming and live streaming. WebSockets, while revolutionary in 2011, face challenges in modern use cases due to their reliance on TCP, which can hinder performance in high-speed interactions. WebTransport aims to resolve these limitations.
