Consider the cross$-$country example shown below

a$.$ A stop$-$and$-$wait protocol in operation

b$.$ A pipelined protocol in operation

Figure $3\mathrm{.}17-$ Stop$-$and$-$wait versus pipelined protocol

As discussed in the textbook, each packet has $8000$ bits, the link speed is $1$Gbps and the propagation delay is $15$ ms each way. ACKs are send whenever a packet arrives and the ACKs are small, so that the transmission time of an ACK can be ignored.

How big would the window size have to be for the channel utilization to be greater than $98$ percent? That is$,$ how big would the window need to be so that packets are being transmitted $\backslash (98\backslash \%\backslash )$ of the time.
