• Software Defined Networking / Open Flow - Group Inquiry
• How do we measure openflow and the controllers?
• A few people are running OpenFlow in test
• Question from NYU about measuring openflow on layer 2 and layer 3.
• Stanford wrote some software that will provide some measurements.
• Reminder of The Challenge - Ken
• Survey of hands of people running various monitoring applications
• Cacti, Scripts, RRDtool,
• Community Updates / Open Forum
• Question if anyone is doing sub-second polling to capture microbursts of traffic. Some responded that that's too often, a packet capture would be better. Other responded that they are polling a various intervals. Some said 5 min, 1 min, 15 seconds, but it all depends on if the hardware would handle it. Also the device counters update frequency will need to be adjusted.
• Multicast tools: some are using multicast beacon and some are using dbeacon. NYU mentioned IPv6 Beacons.
