Suppose an application uses rdt. 3.0 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 sending 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 application design increase the channel utilization? Why? Are there any potential problems with this approach? Explain.
