Tour of PerfSONAR-Lite TSS

• Authentication• Data Management

– Register a probe– Manage a probe (access, edit)– Specific features to mitigate GOCDB inaccuracy & downtimes

Manage user (user not registered in GOCDB), new site, new ROC

• Test – Ping, traceroute, DNS lookup, nmap test, BWCTL

Beta-test and deployment

• The beta-testing will last 1 month during March 2010– GARR– CC-IN2P3– EELA– …

• We have asked SA1 help but SA1 answered that we have to find new beta-test sites by our own mean

Future of PerfSONAR-Lite TSS

• Foster the deployment within EGI– Move ENOC installation (CNRS/Lyon) in GARR infrastructure

(Rome)

• A very useful tool for different type of users:– A network provider– A grid project– A big institute which have a lot of units spread over the world

• Future maintenance– No funding for the maintenance for the code; Investigate if there is

a specific task in EGI that could take over the maintenance of the software within EGI

– CNRS is interested in improving and developing the software
