Question 4 (1 point) (This question is related to ILO2a - "be able to comprehend the challenges and explain the principles in providing reliable communication in an unreliable medium", and ILO3 - "be able to calculate packet delay, throughput, and channel efficiency according to different network protocols".) Two hosts are linked directly by a 1 Mb/s channel with a propagation delay of 0.3 second. Assume the system is using frames of 1504 bytes (with 4 bytes for the header and 1500 bytes for the payload). Within the frame's header, 5 bits are allocated for the sequence number. Assume no transmission errors, no data loss and out-of-order arrivals, what is the maximum end-to-end throughput if the following ARQ is used? a) (0.2) Stop-and-Wait (rdt3.0) ARQ b) (0.4) Go-Back-N ARQ c) (0.4) Selective Repeat AR
