Consider sending a large file of F bits from Host A to Host B. There are three links (and two switches) between A and B, and the links are uncongested (that is, no queuing delays). Host A segments the file into segments of S bits each and adds 80 bits of header to each segment, forming packets of L=80+ S bits. Each link has a transmission rate of R bps. Find the value of S that minimizes the delay of moving the file from Host A to Host B. Disregard propagation delay.

Consider sending a large file of F bits from Host A to Host B. There are three links (and two
switches) between A and B, and the links are uncongested (that is, no queuing delays). Host A
segments the file into segments of S bits each and adds 80 bits of header to each segment,
forming packets of L=80+ S bits. Each link has a transmission rate of R bps. Find the value of S
that minimizes the delay of moving the file from Host A to Host B. Disregard propagation delay.
