Case Study:
Congestion control refers to the techniques and mechanism that can either prevent congestion, before it happens, or remove congestion, after it has happened. In general, we can divide congestion control mechanism into two broad categories: Open loop congestion control (Prevention) and Closed-loop Congestion Control (Removal).
In the given TCP network, R1 and R2 are two routers and network 1 and network 2 are the part of this TCP network. The input data rate of router R1 is 7 mb/s and output data rate of same router is 6.53 mb/s. Will there be congestion? If yes then how you will control the congestion in this TCP network?
