LAYERED QUEUEING NETWORK MODELING SOFTWARE Commands: lqns -- Analytical model solver lqsim -- Model simulator srvndiff -- Result file differencer. lqn2ps -- Model formatter and converter Type "<command> --help" for a quick summary of usage. Documents: lqn2ps.pdf -- Postscrpt version of man-page for srvn2eepic. lqns.pdf -- manual page for the analytic solver. lqsim.pdf -- manual page for simulator. srvndiff.pdf -- manual page for srvndiff. tutorial.pdf -- Tutorial for Layered Queueing Networks userman.pdf -- User manual for Layered Queueing Network solvers. Jlqndef: Jlqndef is an editor for Layered Queueing Network model files. It is not included with this package, but is available as a separate download. Requirements for jlqndef: Set the environment variable LQNDIR to the path of the lqn root directory (eg $HOME/lqn). Set the environment variable TMPDIR to the path of the directory in which to store temporary files (eg /tmp). Add the directory $LQNDIR/bin to your executables search path. The graphical model editor is written in java and uses Swing components of Java 2, so either JDK1.2.x or JRE1.2.x must be installed on your machine. These packages are available from Sun Microsystems: http://java.sun.com/jdk. The directory of the java or jre binary must be in the executables search path. To run Java 2, Solaris 2.6 or greater is required. Examples: Change into the $LQNDIR/examples directory and run jlqndef & Load one of the examples using the file menu. The document lqndef.ps has a step-by-step tutorial on using the tool. It will guide you through the examples. There may be some minor differences between the tool and the guide but they should not be a problem. Some Tips: 1) When creating a model with jlqndef, add all the model's processors first, then add the tasks and entries and finally add the calls between entries.
