1. Introduction
The recently proposed QUIC tunnel protocol
[I-D.piraux-intarea-quic-tunnel] supports the exchange of IP packets
and Ethernet frames over a QUIC connection. Its two existing
operating modes transports plain packets inside QUIC frames. Their
main advantage is that they support 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
