Suppose station A tries to send three frames (f0, f1, f2)

Suppose station A tries to send three frames (f0, f1, f2) to station B (there is no frame f3 to send). 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 1.5 time units, and timeout for each frame is seven time units. For each of the following ARQ protocols, complete the frame exchange sequence and send/receive window information until all three frames are delivered successfully. a) Go-Back-N (GBN) ARQ protocol with N 2; b) Selective Repeat (SR) ARQ protocol with ws-wr-2. fo f1
