Review, Clarifications and Conclusions

slide-32
SLIDE 32

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.

–Randy Bush

“This is a measurement study, not an answer study.”

Although, Measurement Matters to the Public

People Need Information

Research Limitations

  • We cannot determine which

actors or actions are “responsible” for observed degradation.

  • Path data is not included in the

scope of this report (but it is collected and consulted by M- Lab).

  • We cannot identify the precise

cause of performance problems (e.g. a broken router) in a path between a client.

Criticisms and Contributions

  • Host a Measurement Lab site.
  • Review Telescope, and extend

it for your own purposes.

  • Access our data and review
  • ur measurement

methodology.

  • Discuss this research on the

discuss@measurementlab.net list.
