Consider sending a large file of F bits from Host Ato 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.



A large file is transmitted with F bits from host A to host B.

No. of links between the hosts A and B is 3

No. of switches that connects the links is 2

The file size is F bits

The each segment size is S bits
