Please don't consider this discussion as questioning the value of your work= , but as a helper. At this stage, I suggest to have first an offline discussion between the CC= AMP Chairs + Ketan (as CCAMP Responsible AD) & IPPM Chairs + Myself (IPPM R= esponsible AD) to see the appropriate way to help this work. After that, I = expect we can come up with a concrete action.

We take the concern regarding CCAMP charter fit seriously. We also agree th= at the current draft would benefit from a clearer statement of scope. Our i= ntention is not to define a broadly technology-agnostic PM model, and we re= cognize that some of the current wording may give that impression. If you could identify the specific sections or text that appear problematic= with respect to the WG charter, that would be very helpful to us. Such gui= dance would assist us in reviewing the draft more carefully and in refining= the text to make the intended scope clearer.

I tend to agree with Qin's observation. The model is too generic. With that in mind, and in order to avoid late surprises (and frustration fo= r authors and WG), I recommend to check that doc falls under the WG charter= . As currently written, my assessment is that it is not within scope as cca= mp focuses on non-packet technology-specific per the following (and similar= mentions in the charter): =3D=3D - Definition of data models and management objects for network control and = management of ** non-packet technology-specific ** network elements, topolo= gies, and abstractions. =3D=3D Unless the scope is changed, generic methods and models do not belong to CC= AMP. Let's please clarify this before making any further action. Thank you.

Please see our brief responses below. 1. On the applicability of CCAMP We believe CCAMP is the appropriate venue for this work. CCAMP covers a bro= ad range of non-packet physical and transport-facing technologies and inter= faces, including OXCs, OEO switches, ROADMs, TDM switches, transponders, mu= xponders, optical amplifiers, microwave links, Ethernet switches, and optic= al pluggables. Because CCAMP addresses such a diverse set of physical inter= faces and transport technologies, a generic model within CCAMP is needed as= a common framework, while allowing technology-specific extensions where ne= cessary. In this sense, the draft is intended as a generic and extensible P= M streaming model for network equipment in the CCAMP context, rather than a= n IPPM-style framework for IP-layer performance metrics. Also, the IPPM charter states that its work is limited to metrics and metho= dologies applicable over transport-layer protocols over IP, and does not sp= ecify measurements over non-IP layers. For this reason, we believe CCAMP is= the better fit for this draft. 2. On the distinction between measurement interval and reporting interval We agree that this distinction should be clarified further in the draft. Ou= r intent is that the sampling interval defines how often raw PM data is col= lected, while the measurement interval defines the period over which the sa= mpled data is aggregated or processed. The reporting interval, by contrast,= concerns when notifications are delivered to subscribers, e.g., via the su= bscription period in YANG Push. We will revise the text to make this distin= ction more explicit in the next version.

One quick comment to measurement timing, if my unde= rstanding is correct, this measurement timing is used to measure metrics or= KPIs within network element, the measuring timing parameters include time-= related parameters of sampling, measuring, and reporting performance data. = I am wondering whether measuring interval is same as reporting interval, si= nce I didn't see reporting interval is specified in this draft. -Qin [CCAMP]Working group adoption poll on draft-yoon-ccamp-pm-streaming-04 "Daniele Ceccarelli (dceccare)" <[email protected]<mailto:[email protected]= om>> Fri, 20 March 2026 07:40 UTCShow header<https://mailarchive.ietf.org/a= rch/msg/ccamp/_mpRnupqH9A9MBRTm-O3l2Ko1Mk/> Hi working group, As discussed during the CCAMP session at IETF 125 we're starting the workin= g group adoption call on draft-yoon-ccamp-pm-streaming-04.
