A new draft for the QUIC protocol:
This document specifies a profile of the QUIC protocol and the HTTP/ QUIC 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.
