- Software Releases
Last official release of perfSonar -ps and the Toolkit in 2009
...
Longer term - AA integration into ps tools, Configuration management, Possible rewrite of NDT and integration with BWCTL, evaluation of TCP implementation - right now is RENO
- Product Adoption:
USATLAS continues to utilize pSPT, preparing recommendations for Tier 3's
...
Google MLAB- Deployment continues, NDT development in the past year has been driven by MLAB
- Standardization
Continue to be heavily involved in OGF participation. Four working groups: NM, NMC, NML, NSI
- Outreach
a) SC09
I2 assisted REDDnet in a BW Challenge entry
ION and I2 connections to Portland 20G total
perfSONAR measurement infrastructure at SC'09 covered in Aaron's talk today!
Matt Z will lead Scinet be leading SCinet Measurement next year
b) APAN - next week
- Other
Open positions on the team!

Discussion about backup of measurement data on toolkit hosts. Consider moving data to alternate location for long term archiving. Toolkit not really designed with robust backup capability.
2. eduPERT activity (http://edupert.geant.net/) Chris Welti, SWITCH

"How should an active measurement service operate within an
experimenter's slice (encompassing Internet2 backbone resources)
in the GENI facility?"
See:
http://www.internet2.edu/presentations/jt2010feb/20100202-calyam.pdf
Discussion:
What does GENI stand for? Global Environment for Network Integration
...
Here in SLC implementation, not possible to request slices that exceed hw capacity.

"PRESTA 10G, a 10Gbps network interface card (NIC) with highly-accurate traffic-measurement capabilities"
See:
http://www.internet2.edu/presentations/jt2010feb/20100201-sebayashi.pdf
Has presta 10G been looked at for bulk data transfer
Approximate cost of a card is 3000.
