+In the first chapter, we explore various approaches of visualising and
+monitoring a network system. Then, in chapter \ref{ch:net}, we understand the
+behaviour of relevant networking technologies. From that, we derive a design
+for Bidrvisu in chapter \ref{ch:design}. Chapter \ref{ch:usage} explains usage
+of the program. At the end, we demonstrate how the project works in network
+systems of various sizes.
