Use of IT Guru

•IT Guru provides a virtual environment that models the behavior of real networks

•This virtual approach saves the time and expense of building the real network in order to plan and test network changes and additions

•It can also be used to diagnose problems, such as traffic growth and network failures

Elements in OPNET

•The first thing to consider in using IT Guru is what elements does it use to create the network models

•These elements are

–Project

–Scenario

–Objects

–Applications Definition Config Node

–Profile Definition Config Node

Project

•A project in IT Guru is a network simulation

•This is where you specify the objects that will form the simulation, the applications that will run on the network, and which objects will run these applications

Scenario

•A scenario is used to alter a project so that what if analysis can be done

•For example, characteristics of objects or applications can be altered to see how this changes network performance

•This includes things such as changing equipment or altering loads on the network
