Subject: [Explicit-meas] I: [EXT] New Version Notification for draft-mdt-ippm-explicit-flow-measurements-02.txt

Two main draft updates.

About packet Loss measurements:
Q-bit and R-bit improved burst loss resiliency. Now there is the correct detection of burst losses up to two Q blocks. In the old draft it was up to one Q block.

About RTT measurements:
new option in the D-bit implementation: D^-bit (hidden Delay bit). We introduced a new feature of the Delay Bit which hides the RTT of the connection while maintaining full visibility on the right half-RTT of the connection (observer-server) and on all intra-domain measures.

The draft will be presented in IPPM WG next session:

https://datatracker.ietf.org/meeting/111/materials/agenda-111-ippm-01

Best regards.

Abstract:
   This document describes protocol independent methods called Explicit
   Flow Measurement Techniques that employ few marking bits, inside the
   header of each packet, for loss and delay measurement.  The
   endpoints, marking the traffic, signal these metrics to intermediate
   observers allowing them to measure connection performance, and to
   locate the network segment where impairments happen.  Different
   alternatives are considered within this document.  These signaling
   methods apply to all protocols but they are especially valuable when
   applied to protocols that encrypt transport header and do not allow
   traditional methods for delay and loss detection.
