1.  Introduction

   The recently proposed QUIC tunnel protocol [I-D.piraux-quic-tunnel]
   supports the exchange of IP packets or Ethernet frames over a QUIC
   connection.  Its first operating mode, the datagram mode, transports
   plain packets inside QUIC frames.  Its main advantage is that it
   supports any network-layer protocol.  However, this advantage comes
   with a large per-packet overhead since each packet contains both a
   network and a transport header.  All these headers must be
   transmitted in addition to the IP/UDP/QUIC headers of the QUIC
   connection.  For TCP connections for instance, the per-packet
   overhead can be large.

   In this document, we propose a new operating mode for the QUIC tunnel
   protocol, called the stream mode.  It takes advantage of the QUIC
   streams to efficiently transport TCP bytestreams over a QUIC
   connection.  Section 3 describes this new mode.  Section 5 specifies
   the format of the messages introduced by this document.  Section 6
   contains example flows.
