When : It happens on Friday 5 p.m.• Few IT Staff available• Friday 5 p.m. is a common schedule
because the timeshift between Chicago and Paris.
What : A non-blocking problem• AccessGrid client is working• No Sound• Hum / noises• No video
No video• Quick to decide the issue
Hum noises• Check the plug
No sound• Check the RAT
Validated on Windows XP / with an already tested AG.• Start AG, only once (don’t click too much)• Go into a venue
Change the bridge -> works as the unicast/multicast is getting reinitialized
Turn off AG client / Restart client -> works as the ports may changes (if a Firewall is filtering) as it’s Windows that give the ports
Turn off the computer / Restart (not useful by itself, but helps end-user to decide)
AccessGrid is mature and works fluently• For example : shared browser / shared ppt
you have some local requirements
• It relies on the operating system for opening the internet ports
• It relies on the IT staff for fixing the filtering rules• It relies on the ability of the end-user to fix quick
problem (hum, defective microphone,…)
