McKeown Group OpenFlow v1.0Weekly Status Report Week2/2011 (01/12 Wed—01/18 Tue)
Status Update WIRED • Pkt-in loop in NEC (Not a NEC bug) • Resolved. Updated SNAC and NOX DEMO NETWORK • Removed ofwifi overlap on necsw • Moved hpsw4 in place of necsw3 • Problems with aggregation demo. Still debugging.
Status Update WIRELESS • Ofwifi went down several times • New FV is still unstable in ofwifi • Crashed 2 times • At some point, flow setup time gradually gets too large and requires restart • Analysis suggests flow setup time in “SNAC” increase when FV exists • Reported to Rob S for fix • Two APs are installed in CIS/CISX 3
Performance Summary WIRED NETWORK • Spikes in RTT • Non-OpenFlow network also has this spike
Performance Summary WIRELESS NETWORK • Unstable flow setup time • Spikes in RTT • Both are due to slow-down of FV
Network Configuration We’ll use this color code for the switch Controller (at openflow5.stanford.edu) SNAC (v1.0 wire compat) Non-OF uplink necsw6 hpsw3 Masa indigo1 Paul • Adam • Payman • Brandon/David E/Glen • Lots of power meters netfpga1 Dan Srini/Tatsuya/Rob
Measured metrics(no change) • Switch Statistics • Active flows • Flow injection rate • CPU usage • Traffic volume • Network Performance • Flow setup delay • E2E RTT • E2E packet loss rate • wget delay
Total Traffic Volume per switch Not available for indigo1 nor netfpga1
Network Performance • Flow setup delay • E2E RTT • wget delay 14
Flow Setup Delay Percentage of time flow setup delay is less than the target value 16
RTT E2E RTT from each switch 17
RTT Percentage of RTT is less than the target value 18
wget delay 19
Network Configuration (no change) We’ll use this color code for the switch Controller (at openflow1.stanford.edu) SNAC (v1.0 wire compat) FlowVisor (currently removed due to slow flow setup time) Non-OF uplink necsw4 necsw1 24 tunneling APs ap2 ap17 ap18 ap15 ap16 ap2 ap2 ap2 ap2 ap2
