 Group - Meeting Minutes*

February 02, 2010, 12:30 PM - 1:50 PM

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/|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.


*Community Presentations*
