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)

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)
