Consider the Stop-and-Wait protocol. Sender A is communicating with sender B. It takes 5 ms to send a packet from sender A to sender B and the acknowledgement from sender B back to sender A. The probability of a packet loss is 0.15, with packets being lost independently. a) If there are no packet losses, what is the throughput of this connection? b) If the retransmission time out is set to 10 ms, what is the throughput of this connection? c) What is the best-case throughput?
