QUIC stands for Quick UDP Internet Connections.
QUIC is an experimental protocol by Google that is based on UDP and targeted at improving situations when you need multiple parallel sessions between two entities. This is the situation for virtually every web page on the internet, which usually requires more than a single resource file to be transmitted from the web server to the browser.
QUIC finds WebRTC in Google’s latest roadmap where it announced its intentions to experiment with the use of QUIC as a replacement for SCTP for the data channel transport.
