Description
The tool is needed for bandwidth/network testing. It is developed as a servlet and could work outside of OpenMeetings. A user can use the tool for executing network tests. There are five tests available for a user:

1) ping;
2) availability of a required RTMP port;
3) jitter size;
4) download speed;
5) upload speed.

User interface
The client side of the tool is a flash application and reproduced by special indicators set. These indicators will show the status of tests. There are five status types:

1) test does not run yet;

2) test is running;

3) test failed;

4) test passed;

5) test passed and its result is measurable.

Work scenario
When a user enters the application link (for example, http://host:5080/openmeetings/networktesting.swf10.swf?lzproxied=solo) then the tests start running automatically. Also, a user can click to the corresponding indicator to start a test again (or to stop it).

It is possible to see the log of tests running process. A user should click to the top right button (Copy the log to the clipboard), and for example, paste it the log to the e-mail and send it to his system administrator.

Development notes
If you want to compile the tool then you need to:

1) run ant compile.laszlo.networktesting ;

2) set up the file dist/red5/webapps/openmeetings/networktesting-config.xml ;
Example:
<hostAddress>localhost</hostAddress>
<rtmpPort>1935</rtmpPort>
<httpPort>5080</httpPort>
<uriContext>/openmeetings</uriContext>
<rtmpUriPath>/openmeetings/hibernate</rtmpUriPath>

3) enter the tool link;
Example:http://host:5080/openmeetings/networktesting.swf10.swf?lzproxied=solo

Improvements and fixed problems (change log)

  • Caching http requests. The first implementation of the tool used simple downloading of files from the server. It provides problems with data caching. The tool architecture was reworked not to use persistent files but to use server side of OpenMeetings. The empty servlet NetworkTestingController was improved to generate non cached http responses.
  • No labels
