US / Canada Mountain
Welcome (5 min)
Co-Chairs: Carla Hunt, MCNC and Chris Hawkinson, CENIC
Community Updates (10 min)
1. Internet2 update, given by Jason Zurawski
Slides are available for further detail.
Software Releases
Last official release of perfSonar -ps and the Toolkit in 2009
Roadmap for 2010 - conversion to RHEL lineage, integrating with Nagios
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
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 groups: NM, NMC, NML, NSI
Outreach
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 next year
APAN - next week
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
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 decide to form a PERT
We are welcome to participate if we have an organization that is interested
Federation based on people and relationships. No tools requirement per se.
Discussion - Does the PERT see emergent community-related performance issues or one offs. Typically, one-offs related to TCP buffering issues.
