Demo of OFRewind for debugging OpenFlow-enabled networks

[Srini Seetharaman]

1. Brief demo description We will demonstrate how OFRewind, a system capable of recording and replaying network events, can be used to debug OpenFlow controller and switch issues. OFRewind, which works in most OpenFlow-enabled networks, provides several knobs for debugging issues: 1) control over the topology (choice of devices and their ports), 2) timeline, 3) subset of traffic to be collected and then replayed. We expect OFRewind to play a major role in helping ongoing OpenFlow deployment projects resolve production problems.

2. List of equipment that will need AC connections 2 laptops, 1 monitor

3. Number of wired network connections (include required bandwidth if significant) 0

4. Number of wireless network connections (include required bandwidth if significant) 2

5. Number of static addresses needed (if any) No

6. Projector (y/n) (Bring your own projectors if feasible) Yes!

7. Monitor (y/n, specify VGA or DVI) Yes, DVI.

8. Number of posters (max size poster boards are 30" x 40") 2

9. Description of any special requests (include any non-commercial network connectivity needs, projects you'd like to be located near, etc.) Preferrably located near OpenFlow projects.
