Hello to all,

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

What Makes This Different

While ther= e are several bufferbloat testing tools available, this platform addresses = a critical gap: ISP-deployable infrastructure that provides both traditiona= l testing and realistic household simulation.

As Dave T=C3=A4ht high= lighted in his influential article "What's Wrong with Speed Tests&quo= t;, traditional speed tests fail to measure what users actually experie= nce. We tried to address Dave's points to make a better speed test that= focuses on the metric that matters: latency under load in realistic usage = scenarios.

Two Complementary Test Modes

Single User= Test Mode
  • Traditional sequential load testing (baseline =E2= =86=92 download =E2=86=92 upload =E2=86=92 bidirectional)
  • Measures = working latency and jitter during each phase
  • Familiar A+ to F gradi= ng based on latency under load increases
  • Comparable to existing too= ls like DSLReports Speed Test and Waveform Bufferbloat Test
Virtual Household Mode (The Innovation)

Process-isolated si= mulation of 4 concurrent users with authentic traffic patterns:
  • = Alex (Gaming): 1.5 Mbps constant, jitter-sensitive for competitive gaming
  • Sarah (Video Conference): 2.5 Mbps bidirectional, Teams simulation w= ith working latency monitoring
  • Jake (Netflix HD): 25 Mbps bursts (1= s on, 4s off), realistic streaming patterns
  • Computer (Background): = Up to 200 Mbps continuous download, system updates

Real-wo= rld relevance: Tests latency under load when multiple family members are on= line simultaneously

Advanced grading: Network fairness, jitter measu= rement, and per-user working latency analysis

Why (not only) ISPs= Need This

The traditional approach of sending customers to t= hird-party speed test sites has limitations:
  • No control over= test methodology or server placement
  • Limited correlation with cust= omer support tickets
  • Generic results that don't reflect real-wo= rld usage patterns
  • No integration with ISP operational systems
  • =
This platform enables (not only) ISPs to:
  • Host their= own testing infrastructure with full control
  • Integrate with suppor= t systems via telemetry APIs
  • Provide customers with realistic house= hold testing scenarios
  • Correlate test results with network performa= nce and customer complaints

Open Source & Community=

The entire platform is open source and available here: https:/= /github.com/LibreQoE/bufferbloat_test

We've designed this to= be:
  • Easy to deploy for (not only) ISPs of any size
  • Scie= ntifically meaningful in its measurement methodology
  • Realistic in i= ts simulation of actual household usage
  • Integrable with existing IS= P operational workflows

Community Feedback Requested
We'd love feedback from the bufferbloat.net community on:
  • Test method= ology: Are we measuring the right metrics?
  • Grading thresholds: Do o= ur A+ to F grades align with real-world impact?
  • Virtual household s= cenarios: What other realistic usage patterns should we simulate?
  • I= SP adoption: What barriers exist for ISP deployment?

Te= chnical Discussion

We'd welcome discussion about:
    Measurement accuracy for working latency and jitter in virtual household m= ode
  • Traffic pattern authenticity (gaming, video conferencing, strea= ming)
  • Grading methodology for latency under load in complex multi-u= ser scenarios
  • Integration approaches for ISP operational systems

The platform represents our attempt to bridge the gap betwee= n academic bufferbloat research and practical ISP operations, building on t= he foundational work of researchers like Dave T=C3=A4ht and the broader buf= ferbloat community. We believe that widespread ISP deployment of proper buf= ferbloat testing infrastructure will ultimately benefit the entire internet= ecosystem.

Looking forward to the community's thoughts and f= eedback!

Best regards,

The LibreQoS Team
