OPNET - ITGURU

Internet Technologies

60-375


Agenda

  • Introduction

  • Working with an example


OPNET : Overview

  • Supports Modeling, simulation , and analysis

  • Supports New technologies

  • Quality of documentation

  • Ease of use

  • Suitability for research

  • Supports almost all simulation platforms


Features

  • Animations

  • Configurable objects

  • Hierarchical objects

  • Processing simulation objects

    • Graphs and analysis


OPNET IT Guru Academic Edition

  • Academic software available at:

    • www.opnet.com/itguru-academic/mk-setup.html

  • enables to better understand the core concepts of networking and equips them to effectively troubleshoot and manage real-world network infrastructures.

  • provides a Virtual Network Environment that models the behavior of your entire network, including its routers, switches, protocols, servers, and individual applications.

    • diagnose difficult problems

    • validate changes before they are implemented

    • plan for future scenarios (i.e. growth or failure)


Invoking IT guru


Configuration

  • Edit -> Preferences


Using OPNET

Using the project Editor


Project Editor


Example: small internetworks


Procedure

  • New project

  • New scenario (a project is a group of related scenarios)

  • Set up the scenario (using the wizard)

    • Define topology

    • Define the scale and size

    • Select a background map

    • Associate an object palette to the scenario


Example


Creating the network(object palette)

  • Nodes

  • Links


Creating the network(Rapid configuration)

  • Topology -> Rapid configuration


Node and link models


Example


..example


Adding a server

  • From ObjectPalette: Sm_Int_Server

  • Add a link: 10BaseT

  • Add an application definition object: Sm_Application_Config

  • Add a profile definition object: Sm_Profile_Config


Final scenario


Collecting statistics

  • From a specific object: Object Statistics

  • Form the entire network: Global Statistics

  • Example:

Server Load

(object statistic)

Ethernet Delay

(global statistic)


Global statistic selection
