Hi IPPM，

We have updated two drafts related to one-way delay measurement.
Most of the current one-way delay measurement solutions require time synchronization, which makes it difficult to deploy applications. So, we introduce two measurement solutions that don’t require time synchronization, which are valuable to the applications such as video transmission, industrial control, etc.

More reviews and comments are welcome. The Internet-Draft announcement is below.

Abstract:
   The end-to-end network one-way delay is an important performance
   metric in the 5G network.  For realizing the accurate one-way delay
   measurement, existing methods requires the end-to-end deployment of
   accurate clock synchronization mechanism, such as PTP or GPS, which
   results in relatively high deployment cost.  Another method can
   derive the one-way delay from the round-trip delay.  In this case,
   since the delay of the downlink and uplink may be asymmetric, the
   measurement accuracy is relatively low.  Hence, this document
   introduces a method to measure the end-to-end network one-way delay
   based on a reference delay guaranteed by deterministic networking
   without clock synchronization.The advantage of this solution is that
   it has high measurement accuracy and can test any flow type.
