Hello to all,

We're excited to announce th= e release of the LibreQoS Bufferbloat Test =E2=80=93 an open-source = bufferbloat testing solution designed specifically for ISPs and network ope= rators to deploy for their customers.

What Makes T= his Different

While there are several bufferbloat testing tools = available, this platform addresses a critical gap: ISP-deployable infrastru= cture that provides both traditional testing and realistic household simula= tion.

As Dave T=C3=A4ht highlighted in his influential article "What's Wrong wit= h Speed Tests", traditional speed tests fail to measure what users= actually experience. We tried to address Dave's points to make a bette= r speed test that focuses on the metric that matters: latency under load in= realistic usage scenarios.

Two Complementary Test Modes
<= br>Single User Test Mode
  • Traditional sequential load test= ing (baseline =E2=86=92 download =E2=86=92 upload =E2=86=92 bidirectional)<= /li>
  • Measures working latency and jitter during each phase
  • Famil= iar A+ to F grading based on latency under load increases
  • Comparabl= e to existing tools like DSLReports Speed Test and Waveform Bufferbloat Tes= t

Virtual Household Mode (The Innovation)

Pr= ocess-isolated simulation of 4 concurrent users with authentic traffic patt= erns:
  • Alex (Gaming): 1.5 Mbps constant, jitter-sensitive for com= petitive gaming
  • Sarah (Video Conference): 2.5 Mbps bidirectional, T= eams simulation with working latency monitoring
  • Jake (Netflix HD): = 25 Mbps bursts (1s on, 4s off), realistic streaming patterns
  • Comput= er (Background): Up to 200 Mbps continuous download, system updates

Real-world relevance: Tests latency under load when multiple fami= ly members are online simultaneously

Advanced grading: Network fairn= ess, jitter measurement, and per-user working latency analysis

Wh= y (not only) ISPs Need This

The traditional approach of sendi= ng customers to third-party speed test sites has limitations:
    No control over test methodology or server placement
  • Limited corr= elation with customer support tickets
  • Generic results that don'= t reflect real-world usage patterns
  • No integration with ISP operati= onal systems
This platform enables (not only) ISPs to:
<= ul>
  • Host their own testing infrastructure with full control
  • Inte= grate with support systems via telemetry APIs
  • Provide customers wit= h realistic household testing scenarios
  • Correlate test results with= network performance and customer complaints

  • Open Sourc= e & Community

    The entire platform is open source and availab= le here: https://g= ithub.com/LibreQoE/bufferbloat_test

    We've designed this to b= e:
    • Easy to deploy for (not only) ISPs of any size
    • Scient= ifically meaningful in its measurement methodology
    • Realistic in its= simulation of actual household usage
    • Integrable with existing ISP = operational workflows

    Community Feedback Requested
    <= /b>
    We'd love feedback from the b= ufferbloat.net community on:
    • Test methodology: Are we measur= ing the right metrics?
    • Grading thresholds: Do our A+ to F grades al= ign with real-world impact?
    • Virtual household scenarios: What other= realistic usage patterns should we simulate?
    • ISP adoption: What ba= rriers exist for ISP deployment?

    Technical Discussion
    We'd welcome discussion about:
    • Measurement accurac= y for working latency and jitter in virtual household mode
    • Traffic = pattern authenticity (gaming, video conferencing, streaming)
    • Gradin= g methodology for latency under load in complex multi-user scenarios
    • Integration approaches for ISP operational systems

    The p= latform represents our attempt to bridge the gap between academic bufferblo= at research and practical ISP operations, building on the foundational work= of researchers like Dave T=C3=A4ht and the broader bufferbloat community. = We believe that widespread ISP deployment of proper bufferbloat testing inf= rastructure will ultimately benefit the entire internet ecosystem.

    <= b>Looking forward to the community's thoughts and feedback!

    = Best regards,

    The LibreQoS Team
