Suppose station A tries to send three frames (fo, f1, f2) to station B (there are no more frames to send after f2). Suppose fo is lost on the first attempt, while all other frame transmissions (including re- transmitted data frames and ACK/NAK frames) succeed. Suppose that one-way propagation delay is one time unit, and timeout for each frame is seven time units. For each of the following ARQ protocols, complete a diagram to show the frame exchange sequence and send/receive window information, until all three frames are delivered successfully. An example diagram (to be completed) for Question (1) is shown below. 1) (20 points) Go-Back-N (GBN) ARQ protocol with N = 2; TOT fofi I ITTTTTTT BI IIIIIII 2) (20 points) Go-Back-N (GBN) ARQ protocol with N = 3; 3) (20 points) Stop and Wait (S&W) ARQ protocol; 4) (20 points) Selective Repeat (SR) ARQ protocol with W, = W, = 2; 5) (20 points) A special version of Selective Repeat (SR) ARQ protocol with send window of size W. = 2 Suppose station A tries to send three frames (fo, f1, f2) to station B (there are no more frames to send after f2).
