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.

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
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.
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.
27. Public Interest Data
• Interconnection Study results
were referred to in filings to
United States regulator agency
since the start of this year
alone.
• M-Lab data has been used by
public interest organizations,
private companies and
individual citizens representing
all sides of the debate.
• Cited in dozens of media
articles in interconnection.
