Write a pseudocode and draw a timeline diagram for the sliding window algorithm with SWA = RWS = 4 and SWS = 3 and RWS = 1 frames in the following two situations. Assume the receiver sends a duplicate acknowledgment if it does not receive the expected frame. For example, it sends DUPACK[2] when it expects to see Frame[2) but receives Frame[3] instead. Also, the receiver sends a cumulative acknowledgment after it receives all the outstanding frames. For example, it sends ACK (5) when it receives the lost frame Frame(2) after it already received Frame(3), Frame(4), and Frame[5]. Show the start timer and stop timer wherever necessary. Use a timeout interval of about 2 x RTT.
