1. McKeown Group OpenFlow v1.0 Weekly Status Report Week9/2011 (03/02 Wed —03/08 Tue) 1

2. Status Update WIRED NETWORK Indigo switch performing poorly. We need to debug it further to see why performance became worse. Stopped the NetFPGA switch for debugging reasons Stopped Gates network tests for performance, STP, reorg DEMO NETWORK Still debugging the missing links because of FV upgrade to 0.7 WIRELESS Testing NEC Helios controller Necsw1 moved from SNAC. Hence no statistics available 2

3. Performance Summary WIRED and WIRELESS NETWORK Many spikes in RTT plot for SNAC managed network. Need to add debugging to SNAC and verify.
