One of the first books to provide a comprehensive description of OPNET®
c
IT Guru and Modeler software, The Practical OPNET® User Guide for p
t
Computer Network Simulation explains how to use this software for ui
c
simulating and modeling computer networks. The included laboratory projects
ta
help readers learn different aspects of the software in a hands-on way. e

The book begins with a systematic introduction to the basic features of O
OPNET, which are necessary for performing any network simulation. The N
remainder of the text describes how to work with various protocol layers eP
using a top-down approach. Every chapter explains the relevant OPNET N
t
features and includes step-by-step instructions on how to use the features wE
during a network simulation.

Each laboratory project in the back of the book presents a complete r
simulation and reflects the same progression of topics found in the main kU
text. The projects describe the overall goals of the experiment, discuss the s
S
general network topology, and give a high-level description of the system e
i
configuration required to complete the simulation. mr

Written by two longtime educators and users of OPNET, this guide enables u
readers to understand the complex functionality available in OPNET and lu
a
learn how to perform various tasks in a network simulation. By providing i
td
an in-depth look at the rich features of OPNET software, the book is an
i
invaluable reference for IT professionals and researchers who need to oe
create simulation models. It also helps newcomers understand OPNET by n
organizing the material in a logical manner that corresponds to the protocol
layers in a network.
