1.3 OPNET Modeler
OPNET Modeler is the foremost commercial product that provides network modeling
and simulation software solution among the OPNET product family. It is used widely
by researchers, engineers, university students, and the US military. OPNET Modeler is a
dynamic discrete event simulator with a user-friendly graphic user interface (GUI), sup-
ported by object-oriented and hierarchical modeling, debugging, and analysis. OPNET
Modeler is a discrete event simulator that has evolved to support hybrid simulation, ana-
lytical simulation, and 32-bit and 64-bit fully parallel simulation, as well as providing
many other features. It has grid computing support for distributed simulation. Its System-
in-the-Loop interface allows simulation with live systems which feed real-world data
and information into the simulation environment. It provides an open interface for inte-
grating external object ſles, libraries, and other simulators. It incorporates a broad suite
of protocols and technologies, and includes a development environment to enable mod-
eling of a very wide range of network types and technologies. With the ongoing release of
updated versions, OPNET Modeler incorporates more and more features in order to keep
up with the evolution of communication networks, devices, protocols, and applications.
Hundreds of protocols and vendor device models with source code are already incorpo-
rated in the modeler. OPNET Modeler accelerates the research and development (R&D)
process for analyzing and designing communication networks, devices, protocols, and
applications (see www.opnet.com). OPNET Modeler GUI makes it user-friendly, and
makes it easy for users to begin learning about it and working with it. However, when
trying to progress beyond this initial phase, its full-featured functionalities and powerful
programming interfaces make it difſcult for people to grasp.
OPNET Modeler provides a comprehensive development environment with a full
set of tools including model design, simulation, data collection, and data analysis and
