  1. McKeown Group OpenFlow v1.0Weekly Status Report Week1/2011 (01/05 Wed—01/11 Tue)

  2. Action Plan NovWeek 4 Nov Week 4 Dec Week 1 Dec Week 2 DecWeek 3 Dec Week 4 Jan Week 1 Jan Week 2 Jan Week 3 Jan Week 4 Debug all errors Test bandwidth and CPU slicing Remove ofwifi overlap + use HP Update FlowVisor Demonetwork Easy start Overallproduction Problem survey / debug current network User experience survey Merge in ofwifi network Install FV, OIM Trial of Netgear switch and Beacon controller Test opt-in/expts Wired Rollout new SNAC Stabilize/Debug issues Plan/design Packard/CIX deploy Finishing new image Wireless Deploy New Measurement Plan/design new authentication Deploy New auth Stabilize/Debug issues for new auth 11n for 3A

  3. Status Update WIRED • Pkt-in loop in NEC • Added SNAC debugging messages. • Finally found the bug. Fixed this morning (but need to check this is a real fix). • Merging ofwifi and production wired network • Doing today • Upgraded FlowVisor and it is more stable with low flow setup time

  4. Status Update DEMO NETWORK • Removed ofwifi overlap on necsw • Moved hpsw4 in place of necsw3 (which will be used for testing) 4

  5. Status Update WIRELESS • New flowvisor has reduced flow setup time. Once it was very unstable but now it is stablized • Still experiencing fluctuating flow setup time • Will work on with Rob to debug this issue • Other buildings • Packard: All 15 Aps reflash/configuration done. • 1 AP has Flash Card issue. Need to be replaced.. • Will connect to Gates ofwifi network once it is stablized • CIS: 5 Aps are flashed • Will work with Joe to install them 5

  6. Performance Summary WIRED NETWORK • Everything is normal • New FV reduced the flow setup time to normal • Slow downlink speed from the Internet • Not OpenFlow network issue. Stanford network has some issue

  7. Performance Summary WIRELESS NETWORK • Unstable due to the new FlowVisor’s unstablility • Resolved yesterday • Fluctuating flow setup time • New FlowVisor reduced flow setup time, but still experiencing fluctuating time • Slow downlink speed from the Internet • Not OpenFlow network issue. Stanford network has some issue

  8. Performance (WIRED)

  9. Network Configuration We’ll use this color code for the switch Controller (at openflow5.stanford.edu) SNAC (v1.0 wire compat) Non-OF uplink necsw5 hpsw3 Masa indigo1 Paul • Adam • Payman • Brandon/David E/Glen • Lots of power meters netfpga1 Dan Srini/Tatsuya/Rob

  10. 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

  11. Flow Statistics per switch

  12. Flow statistics (# of active flows)

  13. Flow statistics (flow injection rate)

  14. CPU usage

  15. Total Traffic Volume per switch Not available for indigo1 nor netfpga1

  16. Network Performance • Flow setup delay • E2E RTT • wget delay 16

  17. Flow Setup Delay 17

  18. Flow Setup Delay Percentage of time flow setup delay is less than the target value 18

  19. RTT E2E RTT from each switch 19

  20. RTT Percentage of RTT is less than the target value 20

  21. wget delay 21

  22. Performance (WIRELESS)

  23. Network Configuration (no change) 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) Non-OF uplink necsw4 necsw1 24 tunneling APs ap2 ap17 ap18 ap15 ap16 ap2 ap2 ap2 ap2 ap2
