Recent release of the Network Performance Toolkit
- Presented by Jason Zurawski, Internet2
Jason provided an overview of the pS-Performance Toolkit:
- Historical Perspective
- Performance Problems
- What's in the Box?
- What's in (outside) the Box?
- Lookup and Discovery
- Testing Parameters
See:
http://www.internet2.edu/presentations/fall09/20091005-PerfWG-zurawski.pdfFor discussion:
- Guidelines for scheduling measurement tests (previous wg discussion lead by Joe Metzger)
Discussion:
- Sometimes there is a need to compromise between number of sites and amount of testing
- Good idea to have identical hardware at all sites
- Important to differentiate between problems at the site and problems on the network
- Both scheduled testing and on-demand testing are needed
Geant's experiences with PERTs
- Presentation Presented by Victor Reijs, HEAnet
Victor provided an overview of The Performance Enhancement and Response Team (PERT) at Geant:
- Why is e2e performance hard?
- What is a PERT?
- Brief history of the PERT
- What is eduPERT?
- GN2 PERT experience feedback
- Challenges for eduPERT
- Why you should have a PERT

For discussionDiscussion: - US Regional and State Networks PERT
- Joining efforts with the GEANT distributed PERT
- Is the PERT concept something we could implement here in the US?
- Argument in 2001 was that "we don't have the tools." But now we do have them.
- It would be great to add this human network.
- Tools can help us identify performance problems, but we need help in knowing how to isolate the source. What's the decision tree?
- It was agreed there is lots of potential, and this could add to the value of the Internet2 network. Could help to build value for R&E networking.
- Concerns: How are we going to fund such an effort? If it is an extra service that's part of the network, maybe that could be sold. But what is the value a user will put on it?
- Suggestion: identify network engineers at Tier-2 sites, who need to understand this troubleshooting anyhow to handle LHC requirements, and use them as a cadre from which a PERT could grow. Use a ticketing system and integrate it with Geant's ticketing system.
