El 24 de novembre ha tingut lloc al CSUC aquesta presentació sobre el funcionament del nou node M-Lab (Measurement Lab) instal·lat al Punt Neutre d'Internet a Catalunya (CATNIX). La conferència, que ha anat a càrrec de Collin Anderson, investigador d'M-Lab, ha tingut per objectiu mostrar com funciona aquesta plataforma oberta mesura de xarxa. A més de presentar-la i descriure el seu funcionament, també ha mostrat quines mesures es poden fer contra aquests nodes per treure'n el màxim rendiment.

1. M-Lab and CATNIX
Open Internet Measurement for the Researchers
and the Public

3. Internet Measurement Challenges
Our Goal:
Better Internet connectivity in support of equality of access and opportunity.
Transparency works, but there are problems:
• Most network performance data is proprietary and hidden from the public.
• User collected information is often unreliable and inconsistent.
• Trustworthy measurements require rigorous methods and complete data.
• Maintaining infrastructure for reliable measurement is extremely costly.

8. Open Platform
(Requirements)
• Original Research and
Sustained Usefulness
• Active Measurements
• Open Source Client and Server
• Open and Accessible Data
• Informed Consent
• No Personal Information
• Ethical Approval

9. Open, Diverse Measurement
Rigorous Technical Methods
Provided by Researchers

10. Throughput
Measurements
• M-Lab hosts three active
throughput measurements:
• Network Diagnostic Tool
(NDT)
• BISmark
• SamKnows
• NDT is integrated with
numerous applications and
receives about 600,000 tests
per day.
• Nearly every country is well-
covered.

11. Network
Transparency
• Two active tests:
• Neubot
• Open Observatory of
Network Interference (OONI)
• Measure differential traffic
performance and traffic
classification regimes.
• Detect manipulation of traffic.

12. Path Information
Collect paris-traceroute information
for every measurement.

13. How Does M-Lab
Collect Its Data?
Large Scale Measurement Data

14. Measurement Clients
Performance measurement clients
for informing users of their network
capacity.

15. Website Integrations
Providing network information to
customers.

16. Software Integrations
Enabling better user experience.

17. Hardware Integrations
Better diagnose issue with Internet
connections.

19. Networks are Opaque Critical Data is Often Proprietary, Creating
Information Asymmetries

20. Network Diagnostic
Tool
• M-Lab’s most popular hosted
test, tens of thousands of
measurements daily.
• Simple test of bulk transfer
capacity.
• Multiple NDT implementations
available, across different
languages and for diversity of
purposes.
• All implementations share the
same methodology and are
inter compatible.
