Consider the transfer of a large data file of 10 MBytes (10 million 8-bit characters) from station A to station B using packet switching technique. The two stations A and B are connected by a copper wire of 10 km long. The data rate of the line is 1 Gbps. The propagation speed is 2 x 108 m/s. The file is divided into frames, each of which has a data size of 1500 bits and 160 bits overhead, before transmitting. Station A sends a block of 10 frames and waits for an acknowledgement (200-bit frame) from Station B before sending another block of 10 frames. Assume error-free transmission.
(i) Compute the one-way propagation delay, the transmission time for one data frame and the transmission time for one acknowledgement frame.
(ii) Compute the total elapsed time for sending 10 frames and getting the acknowledgement frame.
(iii) Compute the total time to transmit the entire data file.
(iv) Compute the effective throughput of the system.
