   draft-ietf-bmwg-mlrsearch-00.txt
   https://datatracker.ietf.org/doc/html/draft-ietf-bmwg-mlrsearch-01
   status:
   - This version describes the new logic and examples on throughput intransactions per second, not just packets.  Some more to do in next ver.
   - Discussion between Gabor and Vratko
   - Vladimir's new comments
   - Reviewers Requested!
   >>>> Looking for an update -02 to reflect comments.
   
- Benchmarking Methodology for Network Security Device Performance
   https://datatracker.ietf.org/doc/html/draft-ietf-bmwg-ngfw-performance-11
   status:
   - Draft was updated several times since March 2021 meeting
   - WGLC on -08 ended in May 
   - Doc Shepherd review complete, version 11 addresses Most comments.
   - Revised version needed (then Publication Requested/AD Review)
   >>>>  Authors will produce -12 soon, to fix edits and nits

WG Adoption Review:

 + A YANG Data Model for Network Interconnect Tester Management
https://datatracker.ietf.org/doc/html/draft-vassilev-bmwg-network-interconnect-tester-07
   status:
   - WG Adoption saw one objection and discussion... Tom Petch and Jürgen Schönwälder provided many comments, including Status -> Standards Track
   - Draft updated 25 Oct, 2021 
   - Need YANG Doctor to work with us on this? Q4Warren...
   - Discuss adoption-outcome now. 
   - Vladimir has shared "Yet Another RFC2544 Testimplementation" open-source/hardware implementation with the BMWG.
   >>>>  No clear statements of support yet. 
   >>>>  Not much YANG expertise in BMWG, and Adopt as a Standards track Doc?  
   >>>>  Vlad - Agrees - new adoption call for Stds track, Sarah Also agrees 
   >>>>  Warren gave a quick check of charter - we should be ok...(?)
   >>>>  cross-post to netmod? cc OPSAWG, yang-doctors and Robert
   >>>>  Mailing list Address yang-doctors@ietf.org

Proposals:

 + Benchmarking Methodology for Stateful NATxy Gateways using RFC 4814
   Pseudorandom Port Numbers
 https://datatracker.ietf.org/doc/html/draft-lencse-bmwg-benchmarking-stateful-02
   status:
   - ~5 people have discussed the draft on the list in May-July
   - Reference to procedures in RFC 8219
   - TCP-based testing = compliments the NG security device testing?
   - Revised version of the Draft available - 
   >>>> Gabor shared his test results, which were referenced in e-mail, useful to evaluate scaling to answer questions about differences between Stateful and stateless. v6OPS argued that stateless might be very much worse scaling...
   >>>> Not many had read, Encourage reviewers in Nov and Dec, and then Possible WG Adoption in 2022.
   
NEW !!   

 + Problems and Requirements of Evaluation Methodology for
   Integrated Space and Terrestrial Networks
https://datatracker.ietf.org/doc/draft-lai-bmwg-istn-methodology/
   status:
   - new draft, new participants!  Presenter: Zeqi Lai and co-authors
   - Key question: what limited aspect of the many-dimensional ISTN problem presented here could be pursued for benchmarking network DUT/SUT?
   - IOW, what aspects of the problem can be deferred, and yet keep results meaningful to some audience?
   >>> Sarah B: Any collaborators outside academia? Zeqi: Mostly the work done by the ISTN group. 
   >>> Need to include the user audience of Sat network owners. Need specific set of tests/benchmarks that could help.
   >>> Al: Described past experience, some parts of the architecture can be removed in the lab and still obtain useful results - don't need high power amplifiers or antennas at ground stations, for example.
   >>> Also: this is a REAL Internet Service Now, 4500 satellites, a colleague used one of the serveices at a workshop nad had comparable connectivity and RTT to anyone else, better than some.
   >>> Zeqi: Benchmarking can help to determine design decisions, satellite utilization vs constellation density.
   >>> So, comments on this topic are welcome on the list.
   >>> It would be best if we could involve the current service providers to some extent.
