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. https://www.ietf.org/archive/id/draft-li-ippm-ref-delay-measurement-02.txt https://www.ietf.org/archive/id/draft-li-ippm-deterministic-owd-measurement-01.txt Best Regards Hongwei Yang yanghongwei@chinamobile.com From: internet-drafts Date: 2022-02-10 11:37 To: Danyang Chen; Hongwei Yang; Tao Sun; Yali Wang; Yang Li Subject: New Version Notification for draft-li-ippm-ref-delay-measurement-02.txt A new version of I-D, draft-li-ippm-ref-delay-measurement-02.txt has been successfully submitted by Hongwei Yang and posted to the IETF repository. Name: draft-li-ippm-ref-delay-measurement Revision: 02 Title: One-way Delay Measurement Based on Reference Delay Document date: 2022-02-10 Group: Individual Submission Pages: 10 URL: https://www.ietf.org/archive/id/draft-li-ippm-ref-delay-measurement-02.txt Status: https://datatracker.ietf.org/doc/draft-li-ippm-ref-delay-measurement/ Htmlized: https://datatracker.ietf.org/doc/html/draft-li-ippm-ref-delay-measurement Diff: https://www.ietf.org/rfcdiff?url2=draft-li-ippm-ref-delay-measurement-02 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.
