There is some hope in measuring quic now ---------- Forwarded message --------- From: The IESG <iesg-secret...@ietf.org> Date: Wed, Aug 16, 2023 at 2:30 PM Subject: [ippm] Document Action: 'Explicit Host-to-Network Flow Measurements Techniques' to Informational RFC (draft-ietf-ippm-explicit-flow-measurements-07.txt) To: IETF-Announce <ietf-annou...@ietf.org> Cc: <ippm-cha...@ietf.org>, <i...@ietf.org>, <draft-ietf-ippm-explicit-flow-measureme...@ietf.org>, The IESG <i...@ietf.org>, <rfc-edi...@rfc-editor.org>
The IESG has approved the following document: - 'Explicit Host-to-Network Flow Measurements Techniques' (draft-ietf-ippm-explicit-flow-measurements-07.txt) as Informational RFC This document is the product of the IP Performance Measurement Working Group. The IESG contact persons are Zaheduzzaman Sarker and Martin Duke. A URL of this Internet-Draft is: https://datatracker.ietf.org/doc/draft-ietf-ippm-explicit-flow-measurements/ Technical Summary This document describes protocol independent methods called Explicit Host-to-Network Flow Measurement Techniques that can be applicable to transport-layer protocols between client and server. These methods employ just a few marking bits inside the header of each packet for performance measurements and require collaborative client and server. Both endpoints cooperate by marking and, possibly, mirroring information back and forward on the round-trip connection. The techniques are especially valuable when applied to protocols that encrypt transport headers, since they enable loss and delay measurements by passive on-path network devices. Different techniques are considered within this document. Working Group Summary Like most IPPM documents, this represents strong concurrence from part of the WG and acquiescence from the remainder. Document Quality While this is not a protocol document per se, there are implementations of the mechanisms described in the document. Akamai and Orange have implemented setting and reading of L and Q bits for loss measurements for QUIC traffic. The open source tool spindump by Ericsson research contains logic for reading bits of most proposals in this document. Telecom Italia have implemented setting of delay, RT-loss etc in a forked QUIC implementation. They have also extended spindump and integrated it in measurement tools. Huawei have expressed interest in implementing mechanisms described in the document. Personnel The Document Shepherd for this document is Marcus Ihlar. The Responsible Area Director is Martin Duke. IESG Note This information draft is a merger of 6 (!) different drafts, accounting for the over-long author list. _______________________________________________ ippm mailing list i...@ietf.org https://www.ietf.org/mailman/listinfo/ippm -- Podcast: https://www.youtube.com/watch?v=bxmoBr4cBKg Dave Täht CSO, LibreQos _______________________________________________ Bloat mailing list Bloat@lists.bufferbloat.net https://lists.bufferbloat.net/listinfo/bloat
