As follows, node A has an unlimited data to node C. Node A is using a window-based transport protocol with a fixed window size W. Thus, node A can send a new packet transmission whenever the number of unacknowledged packets is less than W. Suppose that the transmission time of a packet for nodes A, B, C, and the router is 1 unit time, and that an ACK takes 0.5 unit time from node C to node A. In this problem, ignore the propagation delay and processing delay, i.e., only consider the transmission delay and the queueing delay at the router.

Now consider that node B also has an unlimited data to node C, and that node B and node A both use the window size W . Suppose nodes A and B are perfectly scheduled with the equal probability, i.e., no collision. What is the throughput of nodes A? What is the average packet delay?

What is the average throughput (packets/unit time) as a function of window size W? What is the minimum window size that A should choose to achieve a throughput of 10 packets/unit time? Call this value W With this choice of window size, what is the average packet delay (time from leaving node A to arriving at node C)?
