Determine Required Bandwidth
Bandwidth is the measure of a network's capacity or utilization, usually measured in terms of bits per second.
To ensure a smooth administration, Cambium Assessment, Inc.™ (CAI) recommends network bandwidth of at least 20 kilobits per second for each student taking the test at the same time.
Bandwidth consumed by opening the secure browser and accessing a test for the first time is significantly more than when it's opened and accessed again because a lot of nontest content must be cached when the secure browser is first accessed.
Allow Appropriate URLs
Make sure your network's firewalls are open for the URLs provided by CAI. If your testing network includes devices that perform traffic shaping, packet prioritization, or Quality of Service, ensure these URLs have high priority.
If your filtering system has both internal and external filtering, URLs must be allowed in both filters. For more information on configuring filtering systems, see the technology guide for your operating system.
On educator devices, allow these URLs for nontesting sites:
For 2021–22, include these AIR URLs in addition to the ones listed above:
TA and Student Testing Sites
On proctor and student devices, use a wildcard to allow these URLs at the root level because testing servers and satellites may be changed during the school year:
For 2021–22, include these AIR URLs in addition to those listed above:
Required Ports and Protocols
The table below lists the ports and protocols used by the test delivery system. Ensure that all necessary content filters, firewalls, and proxy servers are open.
