What is QUIC?

is a transport-layer network protocol that establishes multiplexed connections between two endpoints over UDP. This works hand-in-hand with HTTP/2 multiplexed connections, allowing multiple streams of data to reach all of the endpoints independently.
Use of QUIC also provides improved response to packet loss. By contrast, HTTP/2 traffic hosted on TCP can suffer head-of-line-blocking delays of all multiplexed streams, if any of the TCP packets are delayed or lost.
