\section{Behaviour of the network in its original setup.}
\FloatBarrier
The figure below shows the network that needed to be created for the assessment work to be compleated.

\begin{figure}[h!]
The following figure shows the throughput of the links once the network is simulated with the NS3 program. It shows the the three data streams all reaching the max throughput on the middle link around the two second mark, the spike preceeding it may be caused due to loss of packets.
