ReArch 2009 (CoNEXT Workshop)
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.
