OPNET IT Guru Demo
This is a short, simple example of OPNET IT Guru to demonstate the basic operations in creating and simulation a model.
Instructions
- Start OPNET IT Guru
- Start a new project: File->New...->Project. Give a useful name to the project and scenario (e.g. ITS413_Demo and Client_Server).
- Follow the dialog boxes, selecting the following options:
- Initial Topology: Create Empty Scenario
- Network Scale: Office
- Size: 100m by 100m
- Model Family: ethernet
- The office area will be created and the Object Palette opened. Place the following objects in the network:
- Application Config
- Profile Config
- ethernet_wkstn (will be our client)
- ethernet_server (will be our server)
- ethernet16_switch (a 16 port switch to connect our client and server)
- 100BaseT links (connect the client to switch and switch to server)
- Give the objects meaningful names by right-click and select Set Name. E.g. Client, Switch, Server, Applications, Profiles.
- In the Application Definition object (now called Applications), right-click and select Edit Attributes
- Select Application Definitions and set the rows to 1
- For Row 0, give the application a name (such as Web)
- In the Description attribute, for HTTP, select Image Browsing
- Press Ok to close the attributes for the Applications.
- Edit attributes for the Profiles, add a new profile with name Web User
- For the Web User profile, add a new application (set rows to 1)
- Select the Web application
- Press Ok to close the attributes for the Profiles.
- Right-click on the Server and select Edit Attributes
- Set Application: Supported Services to All, and then press Ok
- Right-click on the Client and select Edit Attributes
- Under Application: Supported Profiles add a new row and select the Web User profile, then press Ok
- Right-click on the Client and select Choose Individual Statistics
- Select all items under Client HTTP (they will have green ticks after you select them)
- Repeat the above two steps for the Server and Switch, however select the statistics Server HTTP for the Server and Switch for the Switch.
- From the main menu select Simulation->Choose Individual Statistics...
- Under Global Statistics, select all items under HTTP and Ethernet, and then press Ok
- From the main menu select Simulation->Configure Discrete Event Simulation...
- Press the Run button. Your simulation will take several seconds to execute, finally ending with a message showing the Beginning simulation and time and Simulation Completed - Collating Results. Press the Close button.
- From the main menu select Results->View Results...
- Select the following three statistics:
- Object Statistics->Office Network->Client->Client HTTP->Traffic Sent (bytes/sec)
- Object Statistics->Office Network->Client->Client HTTP->Traffic Received (bytes/sec)
- Object Statistics->Office Network->Client->Client HTTP->Page Response Time (seconds)
- Press the Show button.
- After looking at the results (you can right-click in the results window to make changes), return to the View Results window
- Click on the As Is option and select instead average, then press Show again.
- Close both of the plot panels - select Hide for each. Close the View Results window.
- From the main menu select Scenarios->Duplicate Scenario... and select a name such as Client2_Server
- Add a new client (you can use copy and paste) so you now have Client1 and Client2
- From the main menu select Results->Delete All Panels
- Choose the same statistics for Client2 as in the previous scenario, run a simulation and view the results again. Compare the page response time for Client1 and Client2.
- Save your project and start exploring other features of OPNET IT Guru
