Status Update

WIRED• Pkt-in loop in NEC

– Added SNAC debugging messages. – Finally found the bug. Fixed this morning (but need to

check this is a real fix).

• Merging ofwifi and production wired network– Doing today

• Upgraded FlowVisor and it is more stable with low flow setup time

3

Status Update

DEMO NETWORK• Removed ofwifi overlap on necsw• Moved hpsw4 in place of necsw3 (which will be used

for testing)

4

Status Update

WIRELESS• New flowvisor has reduced flow setup time. Once it was

very unstable but now it is stablized• Still experiencing fluctuating flow setup time

– Will work on with Rob to debug this issue

• Other buildings– Packard: All 15 Aps reflash/configuration done.

• 1 AP has Flash Card issue. Need to be replaced..• Will connect to Gates ofwifi network once it is stablized

– CIS: 5 Aps are flashed• Will work with Joe to install them

5

Performance SummaryWIRED NETWORK• Everything is normal

– New FV reduced the flow setup time to normal• Slow downlink speed from the Internet

– Not OpenFlow network issue. Stanford network has some issue

Performance SummaryWIRELESS NETWORK• Unstable due to the new FlowVisor’s unstablility

– Resolved yesterday• Fluctuating flow setup time

– New FlowVisor reduced flow setup time, but still experiencing fluctuating time

• Slow downlink speed from the Internet– Not OpenFlow network issue. Stanford network has some issue
