McKeown Group OpenFlow v1.0 Weekly Status Report Week6/2011 (02/09 Tue—02/15 Tue) 1
2
Status Update WIRED NETWORK Bigswitch controller crashed 2-3 times in a week Fail open mode on HP worked well (From Fri thru Mon, it was fail open mode) FV upgraded to FV 0.7 (but removed) DEMO NETWORK Upgraded to FV 0.7 Started to see a lot of unidirectional links (debugging now) 2

Status Update WIRELESS Still trying to remove other spikes 3
4
Performance Summary WIRED NETWORK None WIRELESS NETWORK Spikes in flow setup time – Trying to reduce further

Measured metrics (no change) Switch Statistics – Active flows – Flow injection rate – CPU usage – Traffic volume Network Performance – Flow setup delay – E2E RTT – E2E packet loss rate – wget delay 7
