OPNET IT Guru Academic Edition

  • Academic software available at:


  • 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)

  • 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

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

Collecting statistics

  • From a specific object: Object Statistics

  • Form the entire network: Global Statistics

  • Example:

Server Load

(object statistic)

Ethernet Delay

(global statistic)
