b) Assume that you have been asked to design the congestion control mechanisnm for a reliable Transport Layer Protocol. The proposed mechanism may assume that all ACK timeouts are due to congestion and it should therefore monitor timeouts to detect congestion. It should also be capable of dynamically adjusting the transmit window size if congestion is detected. It may also incorporate appropriate threshold values to control the rate at which the transmission speed is changed over time. Explain the solution proposed in your answer and why it would work. 13 MARKS b) Assume that you have been asked to design the congestion control mechanisnm for a reliable Transport Layer Protocol.
