Suppose an application uses rdt $3\mathrm{.}0$ as its transport layer protocol. As the

stop$-$and$-$wait protocol has very low channel utilization $($shown in the cross$-$

country example$),$ the designers of this application let the receiver keep send$-$

ing back a number $($more than two$)$ of alternating ACK $0$ and ACK $1$ even if

the corresponding data have not arrived at the receiver. Would this applica$-$

tion design increase the channel utilization? Why? Are there any potential

problems with this approach? Explain.
