d) Consider the stop-and-wait automatic repeat request (SW-ARQ) protocol in the data link layer. (i) State the operations of the protocol and use a schematic diagram to illustrate the operations; [3 marks] ii) Derive an expression for the throughput of the protocol under ideal assumptions. You should express the throughput as a function of the correct frame probability (P), frame duration (T), and the idle time (DT). You may use the formula 1+a+a2+a3+= 1a1,a
