- Software Releases
Last official release of perfSonar -ps and the Toolkit in 2009
Roadmap for 2010 - conversion to RHEL lineage, integrating with Na= gios
Longer term - AA integration into ps tools, Configuration manageme= nt, Possible rewrite of NDT and integration with BWCTL, evaluation of TCP i= mplementation - right now is RENO
- Product Adoption:
USATLAS continues to utilize pSPT, preparing recommendations for Tier 3'= s
USCMS has no official stance on performance measurement
OSG and some performance tools in VDT distribution
GLIF - MANLAN and dynamic circuit interplay demonstration in 2009
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 group= s: 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 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 m= oving data to alternate location for long term archiving. Toolkit not reall= y designed with robust backup capability.
2. eduPERT activity (http://edupert.geant.net/) Chris Welti, SWI= TCH
See:
http://www.internet2.edu/presentati= ons/jt2010feb/20100202-EduPERT-JTech.pdf
Help desk for users of R&E network users
Typically, NOC doesn't see a problem and hands off an issue for further = investigation
Used to be a central PERT for the entire community
Recently implemented a new model where each NREN has implemented its own= PERT
This is a federation of PERTS with some central functions like knowledge= base, directory, accreditation, mailing list
Range from 2 days to 2 hours minimum response time
Knowledge Base - barriers to contribution low, community-based review of= documents, sometimes mailing lists discussions become documents
Reporting on statistics of number of cases worked by PERTs
Also do on-boarding/organized workshops for new organizations that decid= e to form a PERT
We are welcome to participate if we have an organization that is interes= ted
Federation based on people and relationships. No tools requirement per s= e.
Discussion - Does the PERT see emergent community-related performance is= sues or one offs. Typically, one-offs related to TCP buffering issues.
Please see slides for each of the community presentations.
Prasad Calyam, Ohio Supercomputing Center (15min)"How should an active measurement service operate within an<=
br>experimenter's slice (encompassing Internet2 backbone resources)=
in the GENI facility?"
See:
http://www.internet2.edu/presentat=
ions/jt2010feb/20100202-calyam.pdf
Discussion:
What does GENI stand for? Global Environment for Network Integration
What are the metrics for measuring part of a slice? One possibility coul= d be was the slice request fulfilled.
Measurement design so far collects measurement within the same domain as= the slice.
Some passive measurement within and outside the slice
How is a slice provisioned?
built on several different substrates
one option is vlan
could be wireless channels
With shared infrastructure, one consideration could be how do I know whe= n another slice impacted my slice?
-queuing and resource utilization considerations
Here in SLC implementation, not possible to request slices that exceed h= w capacity.

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

A bit of discussion about the data storage format - why RRD? Not entirel= y clear why there was a need to develop an HRA interface.
