              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.
