Summary

Joint session between the Benchmarking Methodology Working Group (BMWG) and IP Performance Measurement Working Group (IPPM). The session covered updates on existing working group documents, new proposed work, and fostered cross-working group collaboration. Key highlights included progress on asymmetrical packets measurement, segment routing benchmarking, responsiveness testing with L4S deployment results, and several new draft proposals for energy efficiency and network testing methodologies.

Key Discussion Points

Working Group Document Updates

MLR Search Draft: Successfully submitted to IESG for publication with recent improvements addressing reviewer comments
Asymmetrical Packets (IPPM): Completed working group last call with productive feedback incorporated, including new conformance flags and operational considerations
Segment Routing Benchmarking: Stable version 04 published addressing comments from Boris and Dan, preparing for working group last call
Container Infrastructure Benchmarking: Ready for working group last call after addressing mailing list feedback on CNI configurations
Responsiveness Testing: Major milestone achieved with L4S deployment showing 10x improvement in working latency on Comcast networks

Technical Discussions

OAM Characterization: Extensive discussion on proposed terminology changes, particularly around "in-packet" classification as subset of "hybrid" OAM
STAMP Extensions: Progress on reflecting IP headers and MPLS headers with open source implementations
Network Tester Configuration: Stable YANG data model ready for working group last call with multiple implementations including open source RFC 2544 testing

New Proposed Work

Source Address Validation Benchmarking: Updated with false positive/negative rates and resource utilization metrics
Energy Efficiency Benchmarking: Methodology for power consumption testing in networking devices
Multiple IP Address Benchmarking: Simple proposal for using multiple IP addresses in RFC 2544 testing
Time Measurement Calibration: Methodology for calibrating timestamp accuracy in network elements
Computing-Aware Traffic Steering (CATS): New benchmarking approach for computer network metrics

Decisions and Action Items

Working Group Last Calls

Container infrastructure benchmarking document to proceed to working group last call
Network tester configuration document to proceed to working group last call
Segment routing benchmarking targeting working group last call next IETF

Document Adoptions

Multiple adoption requests received for STAMP extensions (IP headers and MPLS headers)
Source address validation benchmarking identified as candidate for adoption
Multiple IP address benchmarking requesting adoption

Review Actions

OAM characterization document authors to clarify terminology overlap with RFC 7799
Energy efficiency draft to add subsystem definitions and alignment with Green WG
Missing presenters to send summaries to mailing lists for feedback

Next Steps

Chairs will review adoption requests and prioritize working group last calls after the meeting
IPPM will hold additional session on Thursday for remaining IPPM-specific topics
Authors encouraged to engage with mailing lists for document feedback before formal calls
Evaluation of joint session format based on participant feedback for future meetings
Several authors planning hackathon activities for Montreal meeting

The joint session successfully facilitated cross-working group discussion and identified areas of common interest between BMWG and IPPM communities.
