You are tasked with designing a new reliable transport protocol, which is a pipeline protocol, for a communication link. The capacity of the link is 160 kbps in bot directions, the latency is 125 ms, and the maximum packet size is 1 kBytes. Assum the following: • No re-ordering and processing delays • Sender application always has data to send • Receiver application always picks up data right away • Receiver application buffers out-of-order packets (that result from packet drops) a. (2pts) What is the minimum sender window size (in packets) that will allow yo to take full advantage of the bandwidth? For this part only, assume maximum packe size, no packet loss, and negligible ACK size. b. (2pts) After deciding the sender window size W, in question a, you and your frien are debating how large the receiver window size W, should be. Alice: Wr Bob: If there is no reordering of packets, then there is no benefit to setting Wr. > 1 W = Ws This gives better performance than Wr = 1. However, setting WW, offers no advantages over W₁ = Ws Carol: WW, The larger W, is, the higher the throughput. Hence, Wr should be as large as possible. Who is right? Circle the best answer, and justify your choice. You are tasked with designing a new reliable transport protocol, which is a pipeline protocol, for a communication link.
