Steps at NetSim Emulation Server#

  1. Run NetSim in Administrative Mode and create a basic network Scenario in any stack-based protocol (Any network except Legacy Networks, Wireless Sensor Network, and Cellular Network) in NetSim. Screenshot of a sample scenario in Internetworks is shown below Figure
    Figure4-8
    • Click on the Application icon present on the ribbon and set properties.
    • In the Application Type select Emulation.
    • Select Source 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 and click OK Figure4-9
  2. 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.

During Simulation you will notice a change in the quality of the video being played in the destination PC. This is because the network created in NetSim has errors / delays etc in the links. The impact of this loss / jitter / delay etc in NetSim Emulator is seen on a real video stream

Steps at Destination PC#

  1. Follow steps as provided before in “Running Emulation via GUI–Setting up the NetSim Client”. After performing all the steps at Source PC and NetSim Emulation Server, open VLC Media Player→ Click on Toggle Playlist icon as shown in the below screenshot Figure Figure4-15 Toggle button is circled in red at the bottom of the screen shot
