AGENDA   - 28 participants, total.

WG Status:

 - RFC: 9411, Benchmarking Methodology for Network Security Device Performance
 - WG Adoptions, and Proposals
   
WG Drafts:
   
MLR Search and YANG Model (brief status) 
- One leaf removed in YANG Model, MLR discussed later.
   
 + Benchmarking Methodology for Stateful NATxy Gateways using RFC 4814
   Pseudorandom Port Numbers
https://datatracker.ietf.org/doc/html/draft-ietf-bmwg-benchmarking-stateful-02
   status:
   - comments exchanged on new version   
   - Generating Multiple IP addresses are needed/proposed for the method now. This is not yet implemented. 
   - WGLC?  Start after authors implement proposal and review.   

Proposals: 

 + Considerations for Benchmarking Network Performance in Containerized Infrastructures - Minh-Ngoc Tran
   https://datatracker.ietf.org/doc/html/draft-dcn-bmwg-containerized-infra-10
   - Sharing updates and progress, thanks for reviews
   - Pods are only deployed on Baremetal hosts
   - Revised deployment figures, New 
   - Looking at results from Hackathon 115 some improvement with new OVS
   - Vratko - will review, then review can be part of the adoption call. maybe combined review with Maciek. Eduard And Gabor will also review.
   - ACTION to wait for review notifications, then WG Adoption.

 + Benchmarking Methodology for MPLS Segment Routing - Paolo Volpato 
   Related Draft:
   https://www.ietf.org/archive/id/draft-vfv-bmwg-srmpls-bench-meth-06.txt
   - Paolo: describe the latest updates to address the comments received so far
   - Recap, Need to expand on RFC 5695,  Test SID list is longer than one SID in the RFC
   - Gabor and Bruno provided comments.
   - How is TST 007 used? wrong, meant TST009
   - Louis Chen, Juniper, 3 Comments about: 
   - no affect of certain label operations. 
   - Why have a long list of SIDs? 
   - Also, consider taking action on the QoS of the labels, for scalability. Paolo agreed to expand the text
   - Ask for Volunteer reviews to the list. pre-adoption.


 + Benchmarking Methodology for IPv6 Segment Routing - Eduard Vasilenko 
   Related Draft:
   https://www.ietf.org/archive/id/draft-vfv-bmwg-srv6-bench-meth-06.txt
   - Eduard: describe the latest updates to address the comments received so far 
   - Feedback from Gabor and Bruno - big change to add encapsulations in transit, and more labels 
   - Louis Chen, Juniper, asked about MicroSID is out of scope, not approved yet, doc could be very large if trying to include every possible test.
   - Seek Adoption via volunteer reviewers on the list - try for more participation.
   - ACTION on both SR drafts: seek review assignments pre-Adoption. 

  + Problems and Requirements of Evaluation Methodology for Integrated Space and Terrestrial Networks
   https://datatracker.ietf.org/doc/draft-lai-bmwg-sic-benchmarking/
   status:
   - Presenter: Qi Zhang
   - updated draft with additional considerations, plus new draft
   - Can we define meaningful benchmarking that fits within BMWG's lab-only charter?
   - Key question: what limited aspect of the many-dimensional ISTN problem presented here could be pursued for benchmarking network DUT/SUT?
   - Qi Zhang: review of progress.
   - Regulators and space observations can provide constellation info. Need orbital parameters for testing/report.
   - Ground station and Inter-Sat connectivity need to be determined. Meshes can be formed among near Ground stations. Network links may be used based on delay calculations and link speeds.
   - Slide with OSPF? latencies - How measured? ping used. Telsat has the least number of satellites, so longest latencies <100ms  stiil better than GEO.
   NOTE: all these latency measurements are UN-LOADED - best case...
   - Plan to work on more concrete methods for benchmarking
   - Paolo: Latency tests with IPv4 connectivity? yes. Is IPv6 supported? consider finding this in the future.
   - Qi: Reg info changes frequently - find the representative parameters for repeatable benchmarking.
  


 + LAST - MLR Draft Update - Vratko
   - Current version of draft is out of date
   - Expanded classifications of trial outcomes
   - reviewed 8 example classification of load conditions after a number of trials
   - 


 + AOB
