    page of the Minnesota Assessments portal (http://www.mnstateassessments.org/).


Network requirements

Network Requirements

Internet Requirements

  • A stable, high-speed (wired or wireless) Internet connection is required for online testing.

  • The response time for each assessment depends on the reliability and speed of your school’s Internet network.


Network requirements1

Network Requirements

Internet Requirements

  • Network configuration settings should include the following:

    • Content filters, firewalls, and proxy servers should be configured to allow traffic on the protocols and to the servers listed on the following screen.

    • Session timeouts on proxy servers and other devices should be set to values greater than the average scheduled testing time. If testing sessions are scheduled for 60 minutes, consider session timeouts of 65–70 minutes. This will help limit network interruptions during testing.

    • Data cannot be cached.

    • If your client network uses any devices that perform traffic shaping, packet prioritization or Quality of Service, the IP addresses below should be given a high priority to guarantee the highest level of performance.


Network requirements2

Network Requirements

Allow traffic on the protocols and to the following servers:


Network requirements3

Network Requirements

Common Bottlenecks

  • Routing traffic to and from the Internet

  • Verifying that students are using the secure browser

  • Performance dependent on several factors:

    • Bandwidth

    • Total number of students simultaneously testing

    • Size of test content

    • Secure browser installation

    • Proxy server (if used)

    • Wireless networking system (if used)


Network requirements performance of the online testing system

Network Requirements: Performance of the Online Testing System

Bandwidth

  • Performance can be affected by:

    • Internal network (LAN) traffic

    • Internet traffic from the router

  • LAN should always be analyzed to determine potential traffic for bottlenecks:

    • Schools need to factor bandwidth requirements of testing.

    • Internal bandwidth is not typically a problem. Switches generally operate between 100 megabits per second and 1,000 megabits per second.

    • Most common bottleneck for Internet networks is the ISP’s router connection.


Network requirements performance of the online testing system1

Network Requirements: Performance of the Online Testing System

Number of Students Simultaneously Testing:

  • As the number of students increases, competition for bandwidth increases.

    Size of Content:

  • The size of the test is determined by two factors:

    • the number of items on the test

    • the average size of each item


Wireless networking

Wireless Networking

  • Wireless Security

    • Due to the sensitivity of test-related data, the use of WPA2/AES data encryption is highly recommended.

    • Using encryption/decryption might slightly decrease overall network speed.

    • A properly configured wireless network should provide adequate bandwidth for testing applications:

      • 802.11n is the fastest and most recent IEEE wireless standard, with a throughput of up to 300 megabits per second.

      • 802.11g has a theoretical throughput of up to 54 megabits per second.

      • 802.11b has a theoretical throughput of 11 megabits per second.

  • Ratio of wireless systems to wireless access points (WAPs) of no more than 20:1.


Wireless networking networking standards

Wireless Networking: Networking Standards

  • The two most common networking standards are:

    • 802.11g (54 megabits per second)

    • 802.11n (300 megabits per second) Newer and faster


Wireless networking networking standards1

Wireless Networking: Networking Standards

More Recommendations

  • Wireless connections using an 802.11g access point can reliably support a maximum of 20 PC and/or Mac workstations that use wireless cards with either the 802.11g or the 802.11n standard.

  • Wireless connections using an 802.11n access point can reliably support a greater number of workstations; however, the number of additional workstations that the 802.11n access point can support will be affected by the make and model of the access point equipment.

  • Typically, when all workstations are using an 802.11n wireless card, the 802.11n access point can support approximately 40 computers.

  • Note: In cases where the workstation wireless cards are a mix of 802.11n and 802.11g standards, supported connections should not exceed 50 workstations.

Secure browser overview

Secure Browser Overview

  • All computers used for testing during 2012–2013 must have the appropriate secure browser installed.

  • The secure browser prevents students from accessing other computer or Internet applications or copying test information.

  • The table lists the secure browser versions and their supported operating systems.


Installing the secure browser

Installing the Secure Browser

One-by-One (Manual) Installation

  • From each computer to be used for testing, access the Internet and download and install the browser; OR

  • Download and save the browser onto a media device (such as a Flash drive), and then copy and install the files onto each computer; OR

  • Download the browser and save it to a network folder and copy it onto each computer.

    Additional instructions are available on the Minnesota Assessments portal if you need to install the

    secure browser on computers for which you do not have administration or installation rights.

    Network Installation (Network Administrators)
