1. McKeown Group OpenFlow v1.0 Weekly Status Report
(01/19 Wed—01/25 Tue)

2. Status Update WIRED NETWORK BigSwitch controller managing 1 switch
A few production users; No issues so far
Will grow the network
DEMO NETWORK
All demos working

3. Status Update WIRELESS FV became more stable after a patch on Sunday
Increasing memory size stopped
Still spiky flow setup time
Analyzing which of SNAC or switch is contributing these spikes
Will move to NEC’s product firmware this week, because the blocker SNAC bug was resolved. 3

4. Performance Summary WIRED NETWORK Abnormal flow arrival rate for HPSW3
Still debugging
WIRELESS NETWORK
Spiky flow setup time
Still debugging (SNAC or Switch)
