What is QUIC?

QUIC (Quick UDP Internet Connections, pronounced quick) is an experimental transport layer network protocol developed by Google. QUIC supports a set of multiplexed connections between two endpoints over User Datagram Protocol (UDP), and provided security protection equivalent to TLS/SSL, along with reduced connection and transport latency, and capacity estimation in each direction to avoid congestion. QUIC's main goal is to optimize connection-oriented web applications currently using TCP. An experimental implementation is being put in place in Chrome by a team of engineers at Google.
