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

• AOB

"below the line"

• 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
  https://datatracker.ietf.org/doc/html/draft-dcn-bmwg-containerized-infra-08

  • Ask to share updates and progress at 114 Hackathon
