Using JPerf

JPerf is a graphical front end for the popular network testing tool Iperf. Using JPerf you can quickly test a WAN or LAN connection to determine the maximum network throughput. The test results are automatically graphed and presented in a format that is easy to read. JPerf can also be used to detect packet loss, delay, jitter, and other common network problems.

Steps at NetSim Emulation Server#

  1. Run NetSim in Administrative Mode and create a basic network Scenario in any of the networks except Legacy Networks, Wireless Sensor Network, and Cellular Network. Screenshot of a sample scenario in Internetworks is shown below Figure Figure4-31
    • 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 Figure4-32
  2. Provide the Simulation Time as per the time for which you want Emulation to be performed. Make sure client system(s) are ready and then click Run Simulation.

Steps at Source PC#

Follow steps as provided before in “Emulation Set-up: Setting up the NetSim Client”. Run JPerf and select Client and set Server Address as <Server IP Address>. User can edit the Application Layer options, Transport Layer options and IP Layer options depending on the type of data they want to transmit in the network.

Do not click “Run IPerf” until all the steps at NetSim Emulation Server are done. Also Wireshark (if installed) will automatically start capturing the packets as soon as Emulation. Server starts simulation.

Steps at Destination PC#

Follow steps as provided before in “Emulation Set-up: Setting up the NetSim Client”. Run JPerf and select Server.
