Evaluation of the QUIC transport layer network protocol

Without any doubt, the Transmission Control Protocol (TCP) is one of nowadays most important and widely used internet protocols. The original RFC 793 dates back to the year 1981, and a lot of enhancements have been released since then. Besides TCP, new transport layer protocols are developed from the scratch. One of these new transport layer protocols is Quick UDP Internet Connections (QUIC), initially introduced by Google and currently an Internet Draft at the IETF. QUIC is a reliable transport layer protocol and designed to provide fast connection establishment, congestion control, security, and mobility mechanisms. In this work, the basic functionality of QUIC shall be reviewed and compared to TCP. In a testbed, QUIC shall be deployed and experiments with different communication channels (i.e. different data rates, delays, packet errors) shall be evaluated. Satellite links, which are subject to large delays, are especially interesting in this context.
