1 M-Lab Research and Infrastructure for Interconnection Performance Monitoring Collin
2 M-Lab: A Collaborative and Growing Network Open data and open methodology Diversity of tests: throughput, interference, traffic shaping and path data; Expansion in the U.S. for Transit ISPs Zayo, Cogent, Tata, Level3 and GTT Expansion of M-Lab sites globally to locations in Canada, Africa and Asia
3 Research Update: ISP Interconnection and its Impact on Consumer Internet Performance
4 How Measurement Lab Collects Information Measurements From Everyone
5 Transit ISP X Transit ISP Y Methodology Inferring the Source of Congestion Network Interconnection s Access ISP A Access ISP B
6 Transit ISP X Transit ISP Y? Methodology? Inferring the Source of Congestion? Access ISP A Access ISP B
7 Transit ISP X Transit ISP Y Methodology Inferring the Source of Congestion Access ISP A Access ISP B
8 Transit ISP X Transit ISP Y Methodology Inferring the Source of Congestion Access ISP A Access ISP B
9 5 Transit ISP X Transit ISP Y Methodology Inferring the Source of Congestion Access ISP A Access ISP B
10 Sufficient Sample The United States Constitutes the Largest Source of this Data
11 Inferring Sources of Congestion in Practice Using New York s Comparison
12 Inferring Sources of Congestion in Practice Using New York s Comparison
13 Inferring Sources of Congestion in Practice US Access ISPs and Cogent ( )
14 Inferring Sources of Congestion in Practice US Access ISPs and Cogent ( )
15 Internet Performance Varies Significantly Throughout the Day
16 Diurnal Patterns Are Instructive Expectations of Normal Performance
17 Diurnal Patterns Are Instructive Expectations of Congested Performance
18 Diurnal Cycles In Practice Peak Hours, Peak Disruption
19 Not Limited to Download Latency Sensitive Applications Affected
20 Congestion has not been limited to Interconnections with Cogent or Specific Services.
21 XO and Time Warner Cable Not Limited to Cogent
22 XO and Time Warner Cable Not Limited to Cogent
23 Level 3 and Verizon Not Limited to Cogent
24 Level 3 and Verizon Not Limited to Cogent
25 Congestion is Continuing Congestion as of Q4 2014
26 Normal ISP Congested ISP Percentage of Tests Slow Fast Slow Fast Comparative Performance across ISPs No Access ISPs or Transit ISPs Universally Underperforming
27 Comparative Performance across ISPs No Access ISPs or Transit ISPs Universally Underperforming
28 Comparative Performance across ISPs No Access ISPs or Transit ISPs Universally Underperforming
29 Comparative Performance across ISPs No Access ISPs or Transit ISPs Universally Underperforming
30 Serendipitous Discovery
31 What Happened in Late February? Cross the Board Increases
32 What Happened in Late February? Cross the Board Increases

34 Research Update: Extending the Interconnection Study through Data Extraction Tools
35 Measurement Lab Telescope Python to extract M-Lab data
36 Measurement Lab Observatory Currently US Only
37 Measurement Lab Observatory Currently US Only
38 Our data shows that traffic from specific Access ISP customers across interconnections with specific Transit ISPs experienced degraded performance and that this degradation forms a pattern wherever specific Access ISPs and Transit ISPs exchange traffic.
39 There is still much more in Measurement Lab s dataset. Please explore.
