Let host X sends a file a size of 1500 byte to host Y through routers R1, R2, R3 and R4 respectively in two different ways. Each packet contains 100 bytes of header information along with the user data. Assume that the bandwidth of each link is 107 B/s. In the first case, a single packet containing the complete file is transmitted from X to Y. In second case the file is split into 15 equal parts, and these packets are transmitted from X to Y. Consider only transmission time and ignore processing, queuing and propagation delays with no errors during transmission. What is the difference between the time taken to send the packet in first case and the time taken to send the packet in second case in μs?
