BMWG Summary

BMWG met in Hybrid Mode, with about 22 people attending: most remote and 4 in-person, and without drama. The EVPN draft is officially Dead.  Co-chair Sarah took the action to update the milestones. The WG drafts are both proceeding: MLRsearch is undergoing re-write for clarity (example results should be explained better). The Network Security Device authors will update their draft and try to resolve DISCUSSes incrementally. One DISCUSS requires TSV-dir re-review, and need to contact Tommy Pauly about this.

There are some good proposals to resolve The Objection on WG Adoption for the YANG Model Draft (Title). Good progress on stateful NATxy draft (Action to try for Adoption). Lots of new material and testing by the Containewrized networking team. Two New Proposals on Segment Routing, for MPLS and IPv6, respecitively. Both SR drafts need to follow updates to RFC 2544: Many sections have been updated by later RFCs (e.g., RFC 8912 for Latency) and ETSI NFV TST009 for virtualized DUT Benchmarking.

Agenda as of March 15, 2022

WG Status:

    Benchmarking Methodology for EVPN and PBB-EVPN
    https://datatracker.ietf.org/doc/draft-ietf-bmwg-evpntest/
    status: Dead
	no discussion of this outcome.
	
Sarah will update milestones.

WG Drafts:

    Multiple Loss Ratio Search
    draft-ietf-bmwg-mlrsearch-00.txt
    https://datatracker.ietf.org/doc/html/draft-ietf-bmwg-mlrsearch-02
    status:
        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:
        Revised version needed following IESG Review
        SHOULD requirements and accompanying text - a discussion for everyone!
        Status of other review resolutions

                        Path forward: email out to ADs, deal with Discusses, comments and Eventually, the SHOULDs could be lower case sometimes, also adding the exception case OR converting to SHALL/MUST. New updates of the draft can make progress against DISCUSSes.

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:
        Still one objection, narrowed down to the title

                        the 4 noun string in the title should be considered, but lets hear from the objector. Can make the title shorter - can help withe the Abstract.
                        Rob Wilton very supportive of the work.

Proposals:

    Benchmarking Methodology for Stateful NATxy Gateways using RFC 4814
    Pseudorandom Port Numbers
    https://datatracker.ietf.org/doc/html/draft-lencse-bmwg-benchmarking-stateful-03
    status:
        ~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

                New material in this draft is measurement of Connection tear-down. Comments needed. Two experiments show the value.

    Considerations for Benchmarking Network Performance in Containerized Infrastructures
    https://datatracker.ietf.org/doc/html/draft-dcn-bmwg-containerized-infra-08
        Sharing updates and progress at previous Hackathon
        Tran Minh Ngoc presenting

                Lots of expansion and work in the hackathon events, resulting in much progress since the last time this draft was considered.
                Bill Fenner will send a comment suggesting paired- veth ports instead of returning to Vswitch
                Vratko has read the draft
                Need to see some reviews and comments on the list.

NEW !!

    Benchmarking Methodology for MPLS Segment Routing
    Related Draft:
    https://www.ietf.org/archive/id/draft-vfv-bmwg-srmpls-bench-meth-01.txt

                    Some Benchmarks of RFC 2544 have been updated. See RFC 8912 for Latency and Delay Variation. ETSI NFV TST009 for benchmarking Virual networking and virtual implementations of DUT.
                    Testing is always a good start for proof of concepts in the draft.
                    We don’t use “background” traffic in this work.
                    Need to see some reviews and comments on the list.

    Benchmarking Methodology for IPv6 Segment Routing
