[tsvwg] FW: New Version Notification for draft-kwbdgrr-tsvwg-net-collab-rqmts-03.txt

[Kaippallimalil John <[e-mail]>]

Hi all,

We just posted a new version of Requirements for Network Collaboration Signaling https://datatracker.ietf.org/doc/draft-kwbdgrr-tsvwg-net-collab-rqmts/ that attempts to address all comments in tsvwg (IETF 120 session).

The comments were to reduce requirements, bring the two requirements docs (h2n, s2n) together, focus on what IETF should do, what is covered by existing mechanisms in IETF and examples/research of what has been done.  (see detailed notes at  https://datatracker.ietf.org/doc/minutes-120-tsvwg-202407261630/ ).

Some of the main revisions:
- Focus on per-packet requirements and is complementary to reactive congestion/rate derivation with L4S/ECN/ACK (RTT vs sub-RTT timeframes, see section 3 - Rationale for Per-packet metadata).
- Defines clearly that these per-packet requirements are for any wireless/highly variable rate networks and not specific to 3GPP (see section 6.2)
- Reference (see 5G-Octopus on in-network content adaptation to control congestion...) that points use of metadata to enhance performance in highly variable rate networks.
- Overall, the requirements are reduced by 70% (total of 5 requirements for S2N and C2N and a well-defined model of how they interact - see section 3, Figure 2)

Please have a look at the new version, and we would appreciate any feedback.

Best Regards,
John

Abstract:

   Collaborative signaling from client-to-network and server-to-network
   can improve the user experience by informing the network about the
   nature and relative importance of packets (frames, streams, etc.)
   without having to disclose the content of the packets.  Moreover, the
   collaborative signaling may be enabled so that clients and servers
   are aware of the network's treatment of incoming packets.  Also,
   client-to-network collaboration can be put in place without revealing
   the identity of the remote servers.  This collaboration allows for
   differentiated services at the network (e.g., packet discard
   preference), the sender (e.g., adaptive transmission), or through
   cooperation of server/client and the network.

   This document lists some use cases that illustrate the need for a
   mechanism to share metadata and outlines requirements for both
   client-to-network and server-to-network.  The document focuses on
   signaling information about a UDP transport flow (UDP 4-tuple).
