Load SIP Servlet application

Load tests are done with the application load-sipapp and SIPp.
This application allows testing Cipango in the following modes:

• UAS
• Back to back
• Proxy

SIPp scripts are provided in extras/load-sipapp/src/test/sipp.

Compilation

Load-sipapp is located under the extras directory of your cipango sources directory. To build from the sources, follow these steps:

1. Open a command prompt window and navigate to your cipango root directory
2. Go to the load-sipapp directory and build it:

   cd extras/load-sipapp
   mvn install
   

Testing

1. Start Cipango with right memory configuration (see also Improve performance)

   java -Xmx1700M -Xms1700M -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -jar start.jar etc/cipango.xml

2. configure SIPp environment
   • on Unix/Linux: edit extras/load-sipapp/src/test/sipp/unix/setEnv.sh
   • on Microsoft Windows: edit extras/load-sipapp/src/test/sipp/windows/setEnv.cmd
3. Run the scripts:
   • message.bat/.sh: For a simple MESSAGE test, Cipango acting as UAS
   • ./uac.sh -s uas or uac.bat -s uas: For a simple call test, Cipango acting as UAS
   • uas.sh/.bat then ./uac.sh -s b2b or uac.bat -s b2b: For a simple call test, Cipango acting as Back-to-back user agent
   • uas.sh/.bat then ./uac.sh -s proxy or uac.bat -s proxy: For a simple call test, Cipango acting as a proxy

For tests calls, to add a delay between ACK and BYE requests, add the SIPp parameters -d delay in milliseconds. For instance, ./uac.sh -s uas -d 2000 or uac.bat -s uas -d 2000
