What happened during the Great East Japan Earthquake?

without comments

Our analysis of traffic and routing behavior for a Japanese ISP for the month of March will be available at the end of the year.

What is unique about this paper is that we used iBGP data from a neighboring ISP to study the effect of failures in our ISPs on the outside world.

ReArch 2009 (CoNEXT Workshop)

without comments

Panel from Mark Handley

The data plane is well structured with the different layers of the OSI model. Comparatively, in the control plane, there are a lot of protocols but no structure. These protocols each solve a very specific issue. They do a good job about it but now is the time to take a step back.

The control plane protocols tend to solve three categories of problems:

  • congestion control
  • multi-homing
  • traffic engineering

Or problems resulting from the intersection of two of these categories.

In the presentation, Mark focusses on the intersection between congestion control and multi-homing. He proposes multi-path transport (multipath TCP) to solve this issue. For solving the congestion control and TE intersection problem, he proposes the re-ECN solution from BoB Briscoe.
