1 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

3 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

5 Performance (WIRED) 5

6 Network Configuration hpsw3 netfpga1 indigo1 Masa Paul Rob Dan Adam Peyman Brandon/David E/Glen Lots of power meters 6 Controller (at openflow7.stanford.edu) SNAC (v1.0 wire compat) necsw6 Non-OF uplink hpsw1 Srini BigSwitch Controller

7 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

8 Flow Statistics per switch SwitchAvg # FlowsAvg Flow Setup Rate [flow/sec] necsw indigo netfpga nonof NA 8

9 Flow statistics (# of active flows) 9 Flow stats not available on hpsw3/hpsw1 (BigSwitch does not provide it)

10 Flow statistics (flow injection rate) 10 Flow stats not available on hpsw3/hpsw1 (BigSwitch does not provide it)

11 CPU usage 11

12 Total Traffic Volume per switch 12 Not available for indigo1 nor netfpga1

13 Network Performance Flow setup delay E2E RTT wget delay 13

14 Flow Setup Delay 14

15 Flow Setup Delay switch10ms100ms1000ms necsw Indigo netfpga Nonof Percentage of time flow setup delay is less than the target value 15

16 RTT E2E RTT from each switch 16

17 RTT switch1ms10ms100ms necsw indigo netfpga nonof Percentage of RTT is less than the target value 17

18 wget delay 18

19 Performance (WIRELESS) 19

20 Network Configuration (added necsw3) necsw1 We’ll use this color code for the switch Controller (at openflow1.stanford.edu) SNAC (v1.0 wire compat) FlowVisor (currently removed due to slow flow setup time) necsw4 Non-OF uplink ap17 ap18 ap15 ap16 ap2 24 tunneling APs
