2 When a network performs poorly, its users often complain to the administrators running it and demanding improvements. To improve the performance, the operators must first determine exactly what is going on? To find out what is really happening, the operators must make some measurements. What are these measurements?

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).
