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.

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


   The Document Shepherd for this document is Marcus Ihlar. The Responsible
   Area Director is Martin Duke.


  This information draft is a merger of 6 (!) different drafts,
accounting for the over-long author list.
