Hi all, Thanks for the work already done on the charter proposal! >From my relatively narrow (and mostly IPPM-focused) point of view, the char= ter proposal is already in good shape content-wise. I mainly have some text-related consistency comments; going through them in= chronological order. First comment: The initial part of the charter focuses on "metrics, methodologies, and pro= tocols" with two sentences. Those sentences make sense to me and create a strong context for the charte= r. The paragraph ends with a (to me) surprisingly focused sentence on metrics. The next paragraph then focuses on methodologies. There is no dedicated text on protocols except for briefly mentioning "acro= ss IETF protocols". To me, this first part of the charter could be more consistent: * Leave the first two sentences as they are to set the scope of the cha= rter. * Make the second paragraph about providing more details about the thre= e focus points * Move the "such metrics" sentence to this paragraph * Consider adding a sentence on protocols OR rephrase the paragraph = so that it talks more generally about "metrics, methodologies, and protocol= s" at once * (at least to me, replacing "such metrics" with "such methodolog= ies" or "such protocols" would equally make sense; same goes for the "The m= ethodologies" sentence). * I am struggling a bit to find a good word to capture the three = aspects at once, though. TG> Agree. The consistency can be improved. Before: <remove the following from the first paragraph> Such metrics are intended to provide unbiased quantitative performance meas= urements. After: <move the following to the end of the second paragraph> The protocols focuses on forwarding plane and how they are encoded in the d= ata plane. The metrics are intended to provide unbiased quantitative perfor= mance measurements. Adding to Tim's question about security and Thomas' suggestion, I would pro= pose making the "security building blocks" sentence into a dedicated paragr= aph between the second paragraph and the final "The xxxx WG fosters ..." se= ntence. The main reason is that I think that we could provide a bit clearer context= on these building blocks. Also, the WG is responsible for documenting common security building blocks= and guidance for methodologies and measurement protocols, including guidan= ce on how to handle sensitive and vulnerable metrics. Specifically, to me, it is not only about handling sensitive data (in a sen= se of protecting confidentiality and privacy) but also about making sure th= at the methodology cannot (easily) be abused (for which we might want to me= ntion authentication?), that the results are trustworthy (i.e., that we pre= vent tampering), and that the intended deployment scope is clear (especiall= y when the WG works on both, lab and production methodologies). I am not sure if that level of detail is already too specific for a charter= , but I would at least consider adding some text along those lines. Also considering Greg's / Med's comments/suggestions regarding (non-)intrus= ive, would this paragraph be a place to touch upon this aspect from a "safe= ty"(?) perspective? TG> That makes sense to me. How about Before: including guidance on how to handle sensitive and vulnerable metrics. After: including guidance on how to handle sensitive and vulnerable metrics, that = methodologies are safe and cannot be easily abused, and that the results ar= e trustworthy. Second comment: The "Work Items" currently state that The work scope is limited to metrics and methodologies which (in the current form of the charter proposal) again leaves out protoc= ols, especially for someone mostly skimming the charter. For consistency reasons, I would suggest adding protocols here as well. TG> Makes sense. How about: Before: The work scope is limited to metrics and methodologies After: The work scope is limited to protocols, metrics and methodologies Third comment: Lastly, regarding Tim's comment/ Thomas's suggestion I assume the nature of the work in https://datatracker.ietf.org/doc/draft-i= etf-ippm-qoo/ remains covered by the new charter. The text doesn't explicit= ly mention quality assessment frameworks and scoring. Second, it would be a nice nod to Dave T=E4ht to explicitly mention bufferb= loat detection in the charter, with related work like in particular https:/= /datatracker.ietf.org/doc/draft-ietf-ippm-responsiveness/. TG> Both are good points which should be clearly mentioned. How about Before: The WG will also produce terminology documents and recommendations concerni= ng the key performance characteristics of internetworking technologies, or = benchmarks for network devices, systems, and services. After: The WG will also produce terminology documents and recommendations concerni= ng the key performance characteristics of internetworking technologies, or = benchmarks for network devices, systems, and services. This includes also q= uality assessment frameworks, scoring, and bufferbloat detection. Speaking as the editor of the QoO draft, I would have seen QoO in scope of = the proposed charter already through the first sentence of the charter: "[..] develops [..] methodologies [..] that can be applied to the quality [= and] performance [..] of applications [..]". That being said, I do like the nod to Dave and the more explicit mentioning= of quality assessment. However, the latter adds a bit of redundancy (quality / perf. characteristi= cs; assessment / scoring) and the exact meaning of the first sentence was a= nd still is a bit ambiguous to me. Is this about "produce terminology documents and recommendations about 1) KPIs of interne= tworking tech and 2) benchmarks" or is this about "KPIs of internetworking tech and benchmarks"? I am pretty sure it's the first one but I also see the possibility of someo= ne interpreting it as the second one. Maybe the following suggestion could tackle both the redundancy and the amb= iguity? * The WG will also produce terminology documents and recommendations on= key performance characteristics of internetworking technologies, on framew= orks for assessing these characteristics, and on benchmarks for network dev= ices, systems, and services, including related topics such as bufferbloat d= etection. TG> That proposal makes perfectly sense to me. As I said in the beginning, I think that the charter is already in good sha= pe, so please see my comments as additional suggestions that might help mak= ing the charter a bit more precise and easier to understand. Thanks! Cheers, Ike Friendly Note: I send emails at times that work best for me. Please don't f= eel any pressure to reply outside your usual working hours.

Hi, I think this is a good, firm strawman and something that should definitely = be taken forward. Thank you for the work in getting this far. A few comments... I don't understand the "the WG is responsible for documenting common securi= ty building blocks and guidance" line. What are these building blocks? To = someone just reading this charter, it's not clear. Security of measurement= protocols? Measurement of security appliances? Something else? TG> Correct. This needs to be set into context. How about Before: The xxxx WG fosters commonality and comparability of metrics and measuremen= ts across IETF protocols at different layers. Also, the WG is responsible f= or documenting common security building blocks and guidance.

This includes also q= uality assessment frameworks, scoring, and bufferbloat detection. The related WGs (well, RGs) should probably include maprg, both for the wor= k it does that may lead to new proposals for protocol work, and its testing= of drafts/protocols under development in the new combined WG. TG> I think the relationship with MAPRG falls under collaboration and there= fore could be mentioned like this: Before: The WG closely collaborates with the Performance Metrics Directorate per th= e guidance in BCP 170. After: The WG closely collaborates with the Performance Metrics Directorate per th= e guidance in BCP 170 and also with MAPRG. And considering something I'm involved with at the moment, is measurement o= f jumbo frame MTU operation in scope for this WG, e.g., testing for 9000 MT= U end-to-end? It's not clear to me from reading the text. Do we need to = add any paragraph about what's NOT in scope, or do we leave it up to the WG= to decide what it can adopt? TG> From my point of few, this is already to detailed for a charter item. P= erhaps others have a different opinion. I've not added these as issues.

At IETF 125 we had a public joint chartering sessi= on onsite. In that session and during the discussion afterwards, we consoli= dated and simplified the existing charters https://datatracker.ietf.org/wg/bmwg/about/ https://datatracker.ietf.org/wg/ippm/about/ for a new joint charter proposal https://github.com/ietf-ippm/wg-charter/blob/main/ippm-bmwg-joint.md Out of this exercise we highlight that the following items are specific to = BMWG or IPPM today: - applications running over public and private networks - including endpoints in production and lab environments. Where in lab envi= ronments the testing procedures ensure consistent, reproducible, and report= able benchmarking results. - The WG will also produce terminology documents and recommendations concer= ning the key performance characteristics of internetworking technologies, o= r benchmarks for network devices, systems, and services. We added new items to the charter based on recent working group discussions - IETF protocols at different layers - documenting common security building blocks - The WG will also produce terminology documents and recommendati= ons - the WG will specify related manageability aspects, such as YANG= data models for configuration, operation, and Network Telemetry data expor= t - Layer 2 applications can be covered as well but require explici= t approval from the Responsible Area Director. - It specifically coordinates with other WGs such as MPLS, 6MAN, = and SPRING where data plane encapsulations are specified. - The WG liaises with other Standards Development Organizations s= uch as ITU-T, IEEE, 3GPP, and BBF and reaches out to other operator communi= ties such as NANOG, RIPE, and APRICOT. Many thanks to Carsten, Luis, Med, Qin, Marcus, Giuseppe and Sarah for this= proposal. We would like to get reviews and feedback on the joint charter proposal fro= m both working groups. And in particular, we also invite BMWG and IPPM auth= ors to check whether the newly proposed joint charter covers their work acc= urately. - Do you believe that this joint charter covers your existing and= future work? - Do you believe it describes and scopes accurately the current a= nd future work of both working groups? - Is something missing or should be omitted? Why? Please comment on this thread and also feel free to open change proposals h= ere: https://github.com/ietf-ippm/wg-charter/issues We intend to follow up also with the MPLS, 6MAN, and SPRING working groups = once this discussion is stabilizing.
