Go-Back-N (GBN) and Selective Repeat (SR). Suppose window size be 16. Only the 8th packet is lost during transmission. Assume the following: • Packet transmission delay be A, timeout interval be B, and round-trip delay be C. • The path is symmetric in terms of delay. • Timeout is greater than the time to send 16 packets plus the round trip time. • The ACK transmission delay is negligible. How much time will it take to send all 16 packets to the receiver by each protocol? Express the equation using notations mentioned here such as A, B, and C.
