Wolfram to the rescue

Having difficulty understanding packets, TCP and round trip time? I may have a solution for you other than Wikipedia.

Have you heard of Wolfram Demonstrations Project?  Have you visited the website? No? Well, you're missing a lot especially if you aspire to be a connoisseur in the  field of Science, Technology and Math. The name "Wolfram" is actually the last name of the genius scientist and mathematician, Stephen Wolfram. He is also the creator of Mathematica.

This is a dynamic website full of interactive lessons authored by experts all over the world. The demonstrations are from elementary subjects to problems even seasoned researchers are having difficulty grappling with.

Check the website and see what I mean. I embedded a short demonstration abut allocating bandwidth by Transmission Control Protocol. TCP. This demo is very useful for students studying Fundamentals of Networking or TCP-IP classes.


Allocation of Bandwidth by TCP from the Wolfram Demonstrations Project by Damon Wischik

Have you figured out the demonstration above?

The transmission rates of Internet traffic flows are controlled by TCP (Transmission Control Protocol), using an algorithm developed by Van Jacobson in 1988. This Demonstration shows the rates that TCP chooses and the packet drop probabilities that it induces in a simple network with three flows and two links. The three flow rates are shown by how thick the lines are, and each link is labeled with its induced packet drop probability . The rates and packet drop probabilities depend on the link capacities, and on the round trip time (RTT) of each of the flows."
