Figure4-28 2. Click on the Application icon present on the ribbon and set properties. As it is two-way communication, add and create two applications. 3. In both the Application Type select Emulation. 4. In one Application, select Source ID and Destination ID according to the network scenario and change the Source and Destination IP address according to the IP Address of the real system. In the second application, set the opposite of first application, i.e. Source ID and IP address will be exchanged with Destination ID and IP address. (Refer the IP settings in the screenshot to get a clear picture) Figure4-29 5. Provide the Simulation Time as how long you want the Emulation to be performed. Make sure client system(s) are ready and then click Run Simulation.

Steps at Source PC#

  1. Follow steps as provided before in “Emulation Set-up: Setting up the NetSim Client”.
