About this Video:
Design two wired nodes that can connect to each other through a point-to-point network that handles a data rate of 50mbps and a delay of 5ms. The first node acts as a server and the second node acts as a client and they exchange at least 10 packets in a total simulation time of 20 seconds. The maximum packet size is 1024 bytes and 512 bytes. Plot the throughput of each node for the above packet sizes. (Use any charting solution you are comfortable with).
02:40 - Code Explanation (C++)
12:34 - Running the Code in ns3
14:45 - NetAnim for the Animation
18:14 - Tracemetrics (Trace file analysis)
22:14 - Plot using Libreoffice

I am going to take the example of first.cc file. ns-3.38/examples/tutorial/
Copy the above file to ns-3.38/scratch/
To run this file, let's open a terminal
$ cd ns-allinone-3.38/ns-3.38
$ ./ns3 run scratch/first.cc
Change the 1024 to 512 as packet size change the 512.tr in the trace file and compile it again
$ ./ns3 run scratch/first.cc
Open another terminal and go to
$ cd ns-allinone-3.38/netanim-3.109/
$ ./NetAnim
Open the XML file and check the output in the animator window.
Now find the throughput with the help of software called tracemetrics which is already installed. Check the video in my channel for installing tracemetrics
Open another terminal or use the existing terminal
$ cd
$ cd tracemetrics-1.4.0
$ java -jar tracemetrics.jar
