Unbound DATA frames for HTTP/3 CONNECT

Dear HTTP Working Group,

David and I updated our proposal for Unbound DATA frames.
Based on the discussion at IETF124 we limited the proposal to HTTP/3
CONNECT streams.

Looking forward to the feedback and further discussions.

Thank you!


Best Regards,
Yaroslav

Abstract:

   This document defines a new HTTP/3 frame type, UNBOUND_DATA, and a
   corresponding SETTINGS parameter that enables endpoints to negotiate
   its use.  When an endpoint sends an UNBOUND_DATA frame on a CONNECT
   request or response stream, it indicates that all subsequent octets
   on that stream are interpreted as tunneled bytes.  This applies both
   to octets transmitted after CONNECT or extended CONNECT.  The use of
   UNBOUND_DATA removes the need to encapsulate each portion of the data
   in DATA frames, reducing framing overhead and simplifying
   transmission of long-lived CONNECT tunnels.
