1 McKeown Group OpenFlow v1.0 Weekly Status Report Week8/2011 (02/23 Wed —03/01 Tue) 1

2 Status Update WIRED NETWORK Bigswitch managed network is a bit slow if we increase users SNAC managed network became stable after restarting the NetFPGA switch DEMO NETWORK Still debugging the missing links because of FV upgrade to 0.7 WIRELESS Still trying to remove other spikes in RTT Testing NEC Helios controller 2

3 Performance Summary WIRED NETWORK Good performance for SNAC managed network WIRELESS NETWORK Spikes in flow setup time and RTT – Trying to reduce further

4 Performance (WIRED) 4

5 Network Configuration hpsw3 netfpga1 indigo1 Masa Paul Rob Dan Adam Peyman Brandon/David E/Glen Lots of power meters 5 Controller (at openflow7.stanford.edu) SNAC (v1.0 wire compat) necsw6 Non-OF uplink hpsw1 Srini BigSwitch Controller

6 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 6

7 Flow Statistics per switch SwitchAvg # FlowsAvg Flow Setup Rate [flow/sec] necsw indigo netfpga nonof NA 7

8 Flow statistics (# of active flows) 8 Flow stats not available on hpsw3/hpsw1 (BigSwitch does not provide it)
