Summary

The Internet Congestion Control Research Group (ICCRG) session featured presentations and discussions on congestion control evaluation suites, implicit congestion notification, and the adoption of the receive-like-that draft. Key topics included updating existing evaluation tools, the challenges of deploying new congestion control mechanisms in real-world networks, and the potential benefits and drawbacks of implicit congestion notification techniques.

Key Discussion Points

TCP Evaluation Suite Update:
- Discussion on reviving and updating an existing TCP evaluation suite for fair comparisons of congestion control algorithms.
- Interest from the NS3 project in incorporating the suite.
- Debate on the inclusion of AQM and non-TCP congestion control mechanisms like QUIC.
Implicit Congestion Notification (ICN):
- Presentation of an ICN scheme that modifies acknowledgement packets to signal congestion without modifying the sender.
- Concerns raised about potential side effects of delaying acknowledgement packets, such as triggering retransmission timers or impacting HTTP resource loading.
- Discussion of using ECN bits instead of delaying packets for faster congestion feedback.
Receive-Like-That Draft:
- Update on the receive-like-that draft, which allows receivers to control congestion by adjusting the advertised receive window.
- Discussion on the draft's maturity and readiness for publication as an informational RFC.
Call for Contribution:
- David Hayes called for community contributions to the effort of updating the TCP evaluation suite, including defining test characteristics.
- Tom has is interested in people contributing to industry as well.

Decisions and Action Items

Action Item: David Hayes to send an email to the ICCRG mailing list to initiate a discussion group for updating the TCP evaluation suite.
Decision: Chairs to initiate a research group last call on the ICCRG mailing list for the receive-like-that draft.
Action Item: Initiate a poll to see who has read every revision of the draft now or that bad.
Decision: Move forward with publishing this document after last call concludes (assuming positive results).

Next Steps

Establish a discussion group to coordinate the update of the TCP evaluation suite.
Conduct research group last call for the receive-like-that draft.
Evaluate comments from the last call and proceed with publishing the draft if appropriate.
