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 topologyDefine the scale and sizeSelect a background mapAssociate 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
