  1. OPNET - ITGURU Internet Technologies 60-375

  2. Agenda • Introduction • Working with an example

  3. OPNET : Overview • Supports Modeling, simulation , and analysis • Supports New technologies • Quality of documentation • Ease of use • Suitability for research • Supports almost all simulation platforms

  4. Features • Animations • Configurable objects • Hierarchical objects • Processing simulation objects • Graphs and analysis

  5. 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)

  6. Invoking IT guru

  7. Configuration • Edit -> Preferences

  8. Using OPNET Using the project Editor

  9. Project Editor

  10. Example: small internetworks

  11. 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

  12. Example

  13. Creating the network(object palette) • Nodes • Links

  14. Creating the network(Rapid configuration) • Topology -> Rapid configuration

  15. Node and link models

  16. Example

  17. ..example

  18. 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

  19. Final scenario

  20. Collecting statistics • From a specific object: Object Statistics • Form the entire network: Global Statistics • Example: Server Load (object statistic) Ethernet Delay (global statistic)

  21. Global statistic selection

  22. Running a simulation

  23. Running a simulation

  24. Viewing results Object statistic: From Server-> View results-> Select attribute : Load

  25. Viewing results Global statistic: From Workspace-> View results-> Select attribute: Ethernet delay

  26. Expanding the network

  27. Comparing scenarios
