McKeown Group OpenFlow v1.0 Weekly Status Report Week4/2011 (01/26 Wed—02/01 Tue) 1

Status Update WIRED NETWORK hpsw3 was removed for preparing to test BigSwitch controller (last Thur) DEMO NETWORK All demos working 2

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

Performance Summary WIRED NETWORK Abnormal flow arrival rate for HPSW3 – Still debugging WIRELESS NETWORK Spiky flow setup time – Still debugging

Flow Setup Time breakdown (Wireless VLAN) 5 Spikes due to Switch Spikes due to SNAC

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 11 Controller (at openflow5.stanford.edu) SNAC (v1.0 wire compat) necsw6 Non-OF uplink Removed ~10am Jan 27 (last Thr)

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 12
