Topics 2 Site Readiness Network Requirements Hardware and Software Requirements Secure Browser Installation Network Diagnostics and Configuration SC-Alt Portal

Objectives 3 By the end of this presentation, you should be able to: Locate information on the Portal Understand your role and responsibilities Prepare for online tests in your school district Install the Secure Browser Troubleshoot technical problems during the tests.

Technology Coordinator Tasks 4 Logins and passwords Minimum system requirements Secure Browser Determining system readiness and network capacity Troubleshooting technical issues

Network Configuration 5 Session timeouts on proxy servers and other devices should be set to values greater than scheduled testing time. If test sessions are scheduled for 60 minutes, consider session timeouts of 65– 70 minutes. Web proxy servers must be configured to NOT cache data received from servers. For any device that performs traffic shaping, packet prioritization, or quality of service, the URLs to be used for testing should be given a high priority.

Whitelisting 6 Content filters, firewalls, and proxy servers should be configured to allow the URLs for testing sites and applicable non-testing sites.

Network Requirements 7 System URL to Whitelist Non-Testing Sites SC-Alt Portal and Secure Browser installation files http: //sc-alt. portal. airast. org/ Test Information Distribution Engine Online Reporting System https: //sc. tide. airast. org/ https: //sc. reports. airast. org/ *. airast. org TA and Student Testing Sites, including *. tds. airast. org TA Interface and Secure Browser *. cloud 1. tds. airast. org *. cloud 2. tds. airast. org

Pop-ups 8 Configure Internet browsers on the Test Administrator Interface device to allow pop-ups from the testing websites.

Performance Factors 9 q q Network bandwidth Number of students simultaneously testing Wireless networking configuration Secure Browser

10 Questions?

Bandwidth 11 At least 20 Kbps bandwidth per student being tested Affected by both Local Area Network (LAN) traffic and Internet traffic from the router LAN should always be analyzed to determine potential traffic bottlenecks

12 Number of Students Simultaneously Testing q q q Network performance may slow when large numbers of students are testing at one time. Multiply the number of students being tested by 20 Kbps to get an estimate of bandwidth needed, and compare that estimate with the network speed test. Perform network analyses at different times to ensure adequate capacity.

Wireless Network Configuration 13 Wireless traffic must use encryption. q q Wi-Fi Protected Access II (WPA 2) Advanced Encryption Standard (AES) Wireless access points have limits on total bandwidth and number of simultaneous devices in use.

Network Performance 14 Testing Device Ratio of Devices to 802. 11 g WAP Ratio of Devices to 802. 11 n WAP 802. 11 g 20 40 802. 11 n 20 40– 50 (depending on the mix of wireless cards used) Mix of 802. 11 g and 802. 11 n
