QUIC-Quick UDP Internet Connections
The results show that QUIC is not better than the other protocols in all scenarios, but it can outperform TCP under certain network conditions.
Abstract
QUIC is a transport protocol on top of UDP, developed by Google. It uses mechanisms of TCP and introduces new features not used by other transport protocols. QUIC is optimized to be used for HTTP/2 connections and aims to reduce the end-to-end latency. QUIC works best (compared to TCP) for slow connections with high latency. This paper addresses the problems of TCP and the mechanisms of QUIC are discussed. QUIC packet and frame types are examined. The performance of HTTP over QUIC is compared to HTTP over TCP and HTTP + SPDY over TCP. The results show that QUIC is not better than the other protocols in all scenarios, but it can outperform TCP under certain network conditions.
