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

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

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

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