           QUIC: A UDP-Based Multiplexed and Secure Transport
                      draft-ietf-quic-transport-02

Abstract

   This document defines the core of the QUIC transport protocol.  This
   document describes connection establishment, packet format,
   multiplexing and reliability.  Accompanying documents describe the
   cryptographic handshake and loss detection.
