One of the critical factor in making the AG work is testing and people. The AG is technologically more advanced than video conferencing systems and is a true collaborative workspace: you can share software applications and work collaboratively on the same document between geographically distributed locations. However somebody at each AG node needs to test the equipment and the network regularly (see the AG quality assurance program below).
- multicast networking must be enabled on your network and on all routers to the upstream provider.
- at least one systems
administrator/programmer
familiar with Linux (and Windows), and audio/video systems to support
and maintain the AG software.
- a trained node
operator needs to be available during AG meetings. This person
can be the sys admin mentioned above or a junior person.
- a room
- equipment: the cost varies depending on the
configuration and how much you are willing to pay for some of the
components (eg projectors);
typically the cost for a room
is around AUD 25,000.

Quality Assurance
Jason Bell at CQU runs the AccessGrid quality assurance program.
Testing runs are done every Monday to tune the network and the hardware
for optimum operation. This has resulted in a performance improvement
in all the sites that participate to the program.
