Warren Kumari on Operations Area Director's Role   
 Still having fun but need more volunteers, talk to Warren.  
 AD role at the IESG review, for many new authors.

WG Status:

*   IESG Comment Resolution, WG Adoptions, and Proposals

WG Drafts:

*   Multiple Loss Ratio Search   
    draft-ietf-bmwg-mlrsearch-02.txt  
    https://datatracker.ietf.org/doc/html/draft-ietf-bmwg-mlrsearch-02  
    status:
    *   detailed update from Vratko:  
        https://mailarchive.ietf.org/arch/msg/bmwg/PQOwW99G3RePA3lQbYuIlnNCAuw/
    *   started a larger rewrite of the MLRsearch draft
    *   lots of earlier material has been commented-out

*   Benchmarking Methodology for Network Security Device Performance  
     https://datatracker.ietf.org/doc/html/draft-ietf-bmwg-ngfw-performance-13
    
     status:  
     - Working with TSV-ART to resolve details needed for TCP traffic   
     - Revised version needed following IESG Review  
     - plan to post again in 2-3 weeks, lots of work in progress and
    with Tommy, TSV reviewer  
     - SHOULDs: most change to MUSTs or explain why SHOULD, defer to n+1
    draft  
     - Thanks to Warren for getting ADs back on board  
     - QUIC is in the test equipment, but review before including
    settings in the draft, Tommy might help

*   A YANG Data Model for Network Tester Management  
     https://datatracker.ietf.org/doc/html/draft-ietf-bmwg-network-tester-cfg
    
     status:  
     - Resolved objection, adopted.  
     - Hackathon@114 - there will be a link to the presentation (after
    Hack-deadline). Multi-stream and reset. See Mail to the list.  
     - Vladimir - reply to Sarah's comments, encourages comments, V
    agrees. YANG Dr review too.  
     - Running code can be tried out, maybe folks have their own use
    cases.

WG Adoption Review:

*   Benchmarking Methodology for Stateful NATxy Gateways using RFC 4814 
    
    Pseudorandom Port Numbers  
     https://datatracker.ietf.org/doc/html/draft-lencse-bmwg-benchmarking-stateful-04
    
    status:  
     - One set of comments exchanged during (so far) adoption call -
    extended  
     - ~5 people have discussed the draft on the list in May-July, 2021 
    
     - Reference to procedures in RFC 8219  
     - TCP-based testing = compliments the NG security device testing?  
     - Another revised version of the Draft available -   
     - novelties of the draft (and also some new measurement results)  
     https://datatracker.ietf.org/doc/html/draft-lencse-v6ops-transition-scalability#section-2.4
    
    *   Slides summarize the draft coverage and history.   
        Covered the new material in Table capacity measurements
        *   Will add v6 set-up as well as v4 current. 2001:0200::/48
            section 8 of \[RFC5180\] and 198.18.0.0/15 (\[RFC3330\]) for
            IPv4 benchmark testing, not 10/8
        *   Tamas Hetenyi has implemented the OS tester and the tests in
            the draft, FPGA-based, and will implement new features. Kind
            of an ulitimate support.
        *   Tim Winters - support for WG doc, qa will review.
        *   Al Proposed adoption after extended call (there have been no
            objections on the list)
        *   Sarah agrees, plenty of support for adoption!

Proposals:

*   Benchmarking Methodology for MPLS Segment Routing - Paolo Volpato   
    Related Draft:  
    https://www.ietf.org/archive/id/draft-vfv-bmwg-srmpls-bench-meth-02.txt
    *   Welcome Paolo!
    *   Definitely need the draft to help SR adoption in the industry.
        Both an operator and a supplier see the need for this. Also
        Boris chatted: SR became useful in operators networks. So this
        work sounds important.
    *   Also the ETSI TST spec should be TST-009, for virtualized
        testing.
    *   The authors have cosidered RFC5695 for MPLS benchmarking and
        cataloged the changed that are required.
    *   Need reviewers, Boris Khasanov recently tested will provide
        feedback

*   Benchmarking Methodology for IPv6 Segment Routing - Eduard Vasilenko
    
    Related Draft:  
    https://www.ietf.org/archive/id/draft-vfv-bmwg-srv6-bench-meth-02.txt
    
     - Same team of authors For SRMPLS, it's really a little late, but
    for SRv6 maybe not: has about 250 projects world wide, need the test
    plan now. It's a little simpler than SR-MPLS.  
     - Again TE and VPN services are excluded in the scope. about 40% of
    the text has changed in this version.  
     - Need at least 2 SIDs in this testing  
     - Need ideas for additional development (review, testing).   
     - Luis Contreras plans some testing after the Summer - report at
    IETF-115  
     - Gabor Lencse - will review after 2 months,  
     - Bor Khasanov - same  
     - Christine - are there any example of testing with the draft -
    Eduard no examples of tests with the draft

*   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?

*   Considerations for Benchmarking Network Performance in Containerized
    Infrastructures
