1. McKeown Group OpenFlow v1.0 Weekly Status Report Week11/2011 (03/16 Wed —03/22 Tue) 1

2. Status Update WIRED NETWORK Upgraded Indigo switch to latest image. Performance deteriorates over time. Need to debug it further. Started control traffic and dataplane traffic dumps. DEMO NETWORK Demo network stable and problems of missing link attributed to wrong flowspace. WIRELESS Testing NEC Helios controller Necsw1 moved from SNAC. Hence no statistics available 2

3. Performance Summary WIRED NETWORK Flow summaries unavailable because BigSwitch controller doesn’t provide it. Performance of hpsw3 and necsw6 very good with BigSwitch controller WIRELESS NETWORK necsw4 RTT is poor. Need to debug SNAC.
