--------------------------------------
Status: Rejected
Type: Technical

Reported by: Nikolai Malykh <nmalykh@ieee.org>
Date Reported: 2021-11-30
Rejected by: Martin Duke (IESG)

Section: 10.1.4

Original Text
-------------
   RTLoss:  This metric assesses the estimated loss count for TCP
      packets constituting a single connection, exchanged between two
      hosts.  We consider the measurement of round-trip delay based on a
      single OP [RFC7011] somewhere in the network.  The output is the
      estimated loss count for the measurement interval.


Corrected Text
--------------
   RTLoss:  This metric assesses the estimated loss count for TCP
      packets constituting a single connection, exchanged between two
      hosts.  We consider the measurement of loss count based on a
      single OP [RFC7011] somewhere in the network.  The output is the
      estimated loss count for the measurement interval.


Notes
-----
This is where loss count is measured, not round-trip delay.
 --VERIFIER NOTES-- 
>From Al Morton: Sorry, but the original text is correct. In this case we have a RT loss *estimate* conducted in the context of (and using the same packets as) the RT Delay measurements described for TCP. We considered this text carefully before publication.
