Technical specifications of our intranet/internet contents

1. Required configuration on work stations

Our intranet/internet courses were developed to be installed on work stations without plug-ins.

Browser: Internet Explorer 4.0 and over; Netscape 4.7 and over; Java plug-in 1.4.0

All our courses were developed with Java and are compatible with the Java 1.4.0 (and more) plug-in. Windows XP do not automatically integrate that plug-in. If it is not installed, the training program will detect it and display a link enabling its installation.

2. Used files

Two types of files are used by our applet to optimize the lessons’ loading time in intranet and internet format.

• Image file: gif type
• Sound file: Very light MP3 type

For your information, a complete module with sounds and images globally represents less than 10 Mb.

Information on the bandwidth for your intranet/internet content

On the first consultation of an Edu-Performance course, a Java applet is loaded with the home page. It includes the course structure, the browsing logic and the AICC and SCORM communications functions. With a volume of about 400KB, it is saved in cache memory on the web server and the client system, the following access time are reduced in drastic fashion.

Here are a few examples of academic charge calculations

Internet solution, 100 Mbits/s network, 1 i-Tutor 2000 server (Application/Data)
1 - Connection for 20 users in a 2 minutes period (connection weight):
Connection page: 44KB including 7KB for the HTML code
Main screen: 35 KB (learner mode, 10 courses) to 80KB (trainer mode, 100 courses), therefore an average of 40KB, including 20 KB for the HTML code
- First connection for every user (no elements in cache memory)
Peak flow: 84 (KB) x 8 (bit/o) x 20 (individuals) /120 (s) = 112 KB/s
- Subsequent connections (elements in cache)
Peak flow: 27 (KB) x 8 (bit/o) x 20 (individuals) /120 (s) = 36 KB/s

2 – Access to EPC courses for 20 learners in a 2 minutes range (connection weight):
Course: 1.1MB including 9KB for HTML code (480 KB applets, around 600 KB for images and sounds).
- First access for every user (no elements in cache memory)
Peak flow: 1100 (KB) x 8 (bit/o) x 20 (individuals) /120 (s) = 1466 KB/s
- Subsequent access (elements in cache)
Peak flow: 9 (KB) x 8 (bit/o) x 20 (individuals) /120 (s) = 12 KB/s
