[Make-wifi-fast] [NNagain] Announcing the LibreQoS Bufferbloat Test Platform

Sun Jun 15 17:40:28 EDT 2025

A-F are not good units. It's not even good to use such graded in schools
(per Alfie Kohn.) Propagating this seems confusing at best.

My latest is packets or bytes in flight. It's part of iperf2 enhanced
outputs on the client side. Linux required

>>
>> *Community Feedback Requested*
>> We'd love feedback from the bufferbloat.net community on:
>>
>>    - Test methodology: Are we measuring the right metrics?
>>    - Grading thresholds: Do our A+ to F grades align with real-world
>>    impact?
>>    - Virtual household scenarios: What other realistic usage patterns
>>    should we simulate?
>>    - ISP adoption: What barriers exist for ISP deployment?
>>
>>
>>
>> *Technical Discussion*
>> We'd welcome discussion about:
>>
>>    - Measurement accuracy for working latency and jitter in virtual
>>    household mode
>>    - Traffic pattern authenticity (gaming, video conferencing, streaming)
>>    - Grading methodology for latency under load in complex multi-user
>>    scenarios
>>    - Integration approaches for ISP operational systems
>>
>>
>> The platform represents our attempt to bridge the gap between academic
>> bufferbloat research and practical ISP operations, building on the
>> foundational work of researchers like Dave Täht and the broader bufferbloat
>> community. We believe that widespread ISP deployment of proper bufferbloat
