Manageability of the QUIC Transport Protocol
draft-ietf-quic-manageability-00
Abstract
This document discusses manageability of the QUIC transport protocol,
focusing on caveats impacting network operations involving QUIC
traffic. Its intended audience is network operators, as well as
content providers that rely on the use of QUIC-aware middleboxes,
e.g. for load balancing.

1. Introduction
QUIC [QUIC] is a new transport protocol currently under development
in the IETF quic working group, focusing on support of semantics as
needed for HTTP/2 [QUIC-HTTP]. Based on current deployment
practices, QUIC is encapsulated in UDP and encrypted by default. The
current version of QUIC integrates TLS [QUIC-TLS] to encrypt all
payload data and most control information. Given QUIC is an end-to-
end transport protocol, all information in the protocol header, even
that which can be inspected, is is not meant to be mutable by the
network, and will therefore be integrity-protected to the extent
possible.
