Fiber Asset Management Software -- Carla Hunt, MCNC
- Eric Boyd asked if the motivation for deploying the fiber database was to meet BTOP requirements.
- Carla said that it was partially motivated to support the BTOP grant, but the bigger interest was to be able to track the fiber, and for planning purposes.
- Jim Warner asked if this software was being used for campuses, or just wide area.
- Carla said that the primary use is for the wide area. The idea was to make it easy for folks whose job was in the campus could easily access the data
ESnet Distributed Help Desk -- Brian Tierney or Phil DeMar, ESnet
- Eric Boyd asked if the 'hub' definition for FermiLab consisted of ESnet's FermiLab box, as well as FermiLab's boxes.
- Phil said that the concept was to have a user-centric view.

- hey don't care who runs the perfSONAR box, just that they can obtain measurements applicable to FermiLab.
- Eric asked if this could be extended to a three-level system (e.g. a hub including regional networks and all universities).
- Phil thought that they would go from at the university level. The basic idea was just to keep users from having to select hostnames.
- Carla Hunt asked if the 'hub' metadata was in the lookup service, or was local to the Web UI. Phil wasn't sure, but figured it was local to the Web UI.
- Jim Warner asked if the cached data was kept around longer than the original perfSONAR services would keep it. A number of folks said that perfSONAR services tend to keep data forever.

IPv6, backbone measurements, and Netflow -- Matt Zekauskas, Internet2
- Matt said that Internet2 has been monitoring for a long time.
- They've been using firewall filters on the Junipers that are configured to soley measure counts, not block anything.
- They've seen 5G of v6 traffic on the backbone.
- The hardware to do proper flow monitoring is expensive though, so they've implemented a workaround.
- They duplicate all IPv6 packets to a local PC (<1G per site), and do flow generation from those packets.
...
- This came online just before IPv6 day, and has been monitoring ever since.
- They've been working on a backend to save and make avialable all these statistics.
- He noted that the data is available if researchers are interested in it, and that it is anonymized (80-bit zeroed, he thinks).
Brian Tierney asked if the backbone bwctl and owamp measurement traffic was using IPv6. Matt said that it was, but that the meaurements being shown was connector traffic, and not backbone traffic.
