Suppose two hosts, A and B, are using a pipelined protocol as the transport layer protocol. For host A, it takes 1 millisecond to transmit a packet into the link (that is, transmission delay = 1 ms). The round-trip time (RTT) between A and B is 24 milliseconds. Assume that ACK packets have negligible length, the window size is N = 5, and the link is reliable, meaning no segments are lost. What is the channel/sender utilization?
