Hi Greg,

Thanks for the comments. STAMP referenced as RFC 8762 has been added as one of PM measurement protocol.
Please be aware this model is a network model and does not specifies the details of STAMP.
Please check whether rev-08 addresses your concerns:
  https://www.ietf.org/rfcdiff?url2=draft-ietf-opsawg-yang-vpn-service-pm-08

Thanks,
Bo

Hi Adrian,
thank you for bringing this work to my attention. I've read and shared my comments earlier. The authors responded promptly and we've worked together to address my comments. After reading the current version I have a question about the importance of identifying the particular active measurement protocol used to measure the reported performance metrics. If reporting the protocol used for the performance measurement is deemed essential to characterize the accuracy of the measurement method, then I would propose to consider several additions to the model:
·         adding STAMP described in RFCs 8762 and 8972 to the list of active measurement methods
·         adding Error Estimate for Session-Sender and Session-Reciever/Session-Reflector for OWAMP, TWAMP, and STAMP
Thank you for your kind consideration.

Regards,
Greg

Hi,

I'm the document shepherd for draft-ietf-opsawg-yang-vpn-service-pm. It has
completed WG last call in the OPSAWG.

The work may be of interest to IPPM and you might want to watch out for the
IETF last call which will be along in due course.

But I'm sure that the authors would welcome any comments you have at any
time.

Best,
Adrian
