Consider the network shown below, where a sender is trying to send data to a receiverthat is $5$ hops away $($i$.$e$.,$ separated by $4$ routers$).$ The first link between the sender andthe first router $($R$1)$ is considered infinitely high that it does not delay any packet andwhatever is sent will instantly reach R$1.$ The following four links all have a bandwidthdelay of $1$ packet$/$second$.$ Now, assume that the receiver is capable of notifying thesender about the reception of packets instantly $($i$.$e$.,$ ACKs travel instantly form thereceiver to the sender$.$ Also assume that there are no propagation delays. The senderuses TCP withssthresh$=6,$ and an initialcwndof $1.$ Assume that the queue at allrouters are large enough so that no packets are dropped
