1 McKeown Group OpenFlow v1.0 Weekly Status Report Week5/2011 (02/02 Wed—02/08 Tue) 1

2 Status Update WIRED and DEMO NETWORK No updates 2

3 Status Update WIRELESS Necsw3 was removed for testing NEC controller (Helios) Still spiky flow setup time – Two cases (see slides 5-9) SNAC: Slow down and flow setup time goes up to seconds. Lasts few minutes. Switch: Occur randomly (does not last). Add few 100ms of seconds. – Switching to product firmware doesn’t change the figure. 3

4 Performance Summary WIRED NETWORK WIRELESS NETWORK

5 Performance (WIRED) 5

6 Network Configuration hpsw3 netfpga1 indigo1 Masa Paul Srini/Tatsuya/Rob Dan Adam Payman Brandon/David E/Glen Lots of power meters We’ll use this color code for the switch 6 Controller (at openflow5.stanford.edu) SNAC (v1.0 wire compat) necsw6 Non-OF uplink Removed ~10am Jan 27 (last Thr)

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

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 necsw3 Removed ~10am Jan 31 (last Monday)
