1 McKeown Group OpenFlow v1.0 Weekly Status Report Week2/2011 (01/12 Wed—01/18 Tue) 1

2 Status Update WIRED Pkt-in loop in NEC (Not a NEC bug) – Resolved. Updated SNAC and NOX DEMO NETWORK Removed ofwifi overlap on necsw Moved hpsw4 in place of necsw3 – Problems with aggregation demo. Still debugging. 2

3 Status Update WIRELESS Ofwifi went down several times – New FV is still unstable in ofwifi Crashed 2 times At some point, flow setup time gradually gets too large and requires restart – Analysis suggests flow setup time in “SNAC” increase when FV exists – Reported to Rob S for fix Two APs are installed in CIS/CISX 3

4 Performance Summary WIRED NETWORK Spikes in RTT – Non-OpenFlow network also has this spike

5 Performance Summary WIRELESS NETWORK Unstable flow setup time Spikes in RTT – Both are due to slow-down of FV

6 Performance (WIRED) 6

7 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 7 Controller (at openflow5.stanford.edu) SNAC (v1.0 wire compat) necsw6 Non-OF uplink

8 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 8
