Opnet simulator free download for windows 7 64 bit

Riverbed Modeler Academic Edition

1) These two Labs are going to be counted as one lab. One report is to be submitted for both Labs.

2) There must be a cover page for your report with your name, Title (Shared & Switched Ethernet Network Simulation using Riverbed Modeller (OPNET)), Course Number (EE450) and Session Number (1, 2, 3, DEN) and that is it.

3) A brief abstract that covers both Labs

4) A diagram of the Simulation Model

5) Answer Questions and provide the Simulation Results with "Labeled Graphs" (i.e. you need to label your graphs as Fig 1; xxxx, Fig 2: yyyy and so on). Any question that asks for "comparison for example simulating the effects on the number of nodes on the Throughput or Delay etc... MUST be sketched on the SAME GRAPH. All your graphs should be "averaged", i.e. I do NOT want to see "wild fluctuations" of the curves (Like Noise), use the averaging tool to generate smooth curves

Introduction

Basics of Riverbed Modeler Academic Edition

Objective

This lab teaches you the basics of using Riverbed Modeler Academic Edition. Riverbed

Modeler Academic Edition enables students to better understand the core concepts of

networking and equips them to effectively troubleshoot and manage real-world network

infrastructures.

Overview

Riverbed's Modeler provides a Virtual Network Environment that models the behavior of

your entire network, including its routers, switches, protocols, servers, and individual

applications. By working in the Virtual Network Environment, IT managers, network and

system planners, and operations staff are empowered to diagnose difficult problems more

effectively, validate changes before they are implemented, and plan for future scenarios

including growth and failure.

In this lab, you will learn the basics of the Riverbed Modeler Academic Edition software.

You will learn how to setup and run Riverbed Modeler Academic Edition. You will become

familiar with some of its preferences and will practice using the software by running some

tutorials.

The labs in this manual are implemented with Riverbed Modeler Academic Edition release 17.5. If your computer meets the system requirements, shown below, and if you want to download the software, please visit the following site to register with Riverbed technology:

Procedure

Start Riverbed Modeler Academic Edition

To start Riverbed Modeler Academic Edition:

1. Click on Start ⇒ Programs ⇒ Riverbed Modeler Academic Edition x.x ⇒

Riverbed Modeler Academic Edition x.x, where x.x is the software version (e.g., 17.5).

2. Read the Restricted Use Agreement and if you agree, click I have read this

SOFTWARE AGREEMENT and I understand and accept the terms and

conditions described herein.

Now you should see the starting window of Riverbed Modeler Academic Edition as

shown:

Check the Modeler Preferences

The Modeler Preferences let you display and edit environment attributes, which control

program operations. In this lab you will check three of those environments attributes.

1. After starting Modeler, from the Edit menu, choose Preferences.

2. Click on the Licensing tab on your right to enter license preferences. The list of

environment attributes is sorted alphabetically according to name and to topic.

You can locate attributes faster by typing any part of the attribute’s name in the

Find field. You can also locate group of environment attributes.

3. Check the value of the license server name attribute. It has the name of the

License Server’s host. If Modeler is getting its license from the local host (i.e.,

the computer on which the software was installed), the value of license server

name should be localhost as shown in the following figure.

4. Set the Standalone License Server attribute to TRUE. This attribute specifies

whether the program acts as its own license server.

5. Enter Model Directories in Search for to find the model directory. A model

directory is a directory that contains Modeler model files. If the directory is listed

in the Model Directories environment attribute, then Modeler programs will use

the models in that directory. Check the value of the Model Directories attribute.

The first directory in the list is where your own models will be saved. In the

future you might need to access that directory to back up, copy, or move your

models. Modeler saves numerous files for every single project you create.

6. Click OK to close the dialog box.

Lab Report

The laboratory report of this lab (and also all the following labs in this manual) should

include the following items/sections:

- A cover page with your name, course information, lab number and title, and

date of submission.

- A summary of the addressed topic and objectives of the lab.

- Implementation: a brief description of the process you followed in conducting

the implementation of the lab scenarios.

- Results obtained throughout the lab implementation, the analysis of these

results, and a comparison of these results with your expectations.

- Answers to the given questions at the end of the lab. If an answer

incorporates new graphs, analysis of these graphs should be included here.
