INTRODUCTION
OPNET provides a comprehensive development environment supporting the modeling of communication networks and distributed systems.
OPNET Modeler provide also a graphical interface easy to use to help the user to build its models.

3. What is OPNET Simulator?
Opnet is a network simulation tool. It allows the definition of:
A network topology,
the nodes, and
the links that go towards making up a network.
User defined:
The processes that may happen in a particular node, and
the properties of the transmission links.
A simulation can then be executed, and the results analyzed for any network element in the simulated network.

MORE ABOUT OPNET
Opnet has three main types of tools:
The Model Development tool
The Simulation Execution tool
The Results Analysis tool
These three types of tools are used together to model, simulate and analyze a network.

5. MODEL DEVELOPMENT TOOL
Network Editor is used to design the network models, with different nodes connected by point-to-point links, radio links, etc.
Node Editor is used to place the models of the nodes used into the network. A node in Opnet consists of modules.
Process Editor is used to define the processes that run inside these modules. Process models are represented by finite state machine (FSMs).
Parameter Editor allows the definition of parameters used in the node modules and process models, such as the packet format, probability density functions, etc.

10. SIMULATION EXECUTION TOOL
Probe Editor is used to place probes at various points of interest in the network model. These probes can be used to monitor any of the statistics computed during simulation.
Simulation Tool allows the user to specify a sequence of simulations, along with any input and output options, and any different runtime options.

16. Invoking OPNET from your CCSE UNIX account
Login to your UNIX account
Use an editor to open the file .cshrc
Add the following entries:
setenv vudoc_prog /usr/local/bin/X11/acroread
set path=($path /tools/opnet/8.0.C/sys/unix/bin)
setenv LD_LIBRARYPATH /usr/openwin/lib:/tools/opnet/8.0.C/sys/sun_sparc_solaris/lib
Save the file and exit from your account
Log on to your UNIX account and at a command prompt, type Opnet. Opnet will start running.
