         Hypertext Transfer Protocol (HTTP) over multicast QUIC
                    draft-pardue-quic-http-mcast-04

Abstract

   This document specifies a profile of the QUIC protocol and the HTTP/3
   mapping that facilitates the transfer of HTTP resources over
   multicast IP using the QUIC transport as its framing and
   packetisation layer.  Compatibility with the QUIC protocol's syntax
   and semantics is maintained as far as practical and additional
   features are specified where this is not possible.
