Goal #4: Network Performance Verification
Mission:
Work with the staffs of the international (Tier0), national
(Tier1), regional (Tier2) and local (Tier3) Grid facilities as needed, to
verify high throughput and network responsiveness, in association with the Grid
projects, and for new collaborative interactive systems.

Activities:
We have developed and set up a network monitoring infrastructure
for meauring high-performance bulk throughput application and network
performance from SLAC to about 35 other grid facilities. Setting this up
required collaboration with the staffs at the remote sites to obtain accounts
etc. The results and data are publicly available from
SLAC WAN Bandwidth Measurement and Monitoring.
The next steps are to prepare and deploy the infrastructure at
other sites. As part of this we hope to engage other sites in the devlopment of
the infrastructure, in particular in the areas of improving security,
developing a distributed gathering and archiving system, and adding new
analysis/reporting tools.
Milestones:
- Develop basic infrastructure to enable robust measurements to
be made on an ongoing basis from a single site. [Done]
- Develop first version of archiving, analysis and reporting
tools. [Done]
- Modify the infrastructure to enable porting the application
to other sites. [In progress]
- Add moredetailed measurements using Web100. [In progress]
- Work with staffs from 2 or 3 other sites to port the
infrastructure and enable those sites to make their own measurements. [Fall
2002]
- Improve the security model for the infrastructure. [Winter
2002]
- Develop a way to gather data from multiple measurement sites.
[Winter 2002]
- Extend archiving, analysis and reporting to encompass
multiple measurement sites.
