QUIC, a multiplexed stream transport over UDP
QUIC is a new transport which reduces latency compared to that of TCP. On the surface, QUIC is very similar to TCP+TLS+HTTP/2 implemented on UDP. Because TCP is implemented in operating system kernels, and middlebox firmware, making significant changes to TCP is next to impossible. However, since QUIC is built on top of UDP, it suffers from no such limitations.
Key features of QUIC over existing TCP+TLS+HTTP2 include
- Dramatically reduced connection establishment time
- Improved congestion control
- Multiplexing without head of line blocking
- Connection migration
