Question 3 (20 points): 40 Mbps 10 ms propagation delay 20 Mbps 50 ms propagation delay 50 Mbps 5 ms propagation delay Figure 1 Consider the scenario in Figure 1, in which (from the bottom up) three hosts are connected to a router and to each other by a 50 Mbps link, with a 5 ms propagation delay. That router in turn is connected to another router over a 20 Mbps link with a 50 ms propagation delay, and that latter router is connected to two remote servers, each over a 40 Mbps link with a 10 ms propagation delay. a. Suppose Host C sends a message directly to Host A. The message is 10K bits long. What is the end-to-end delay from when the message is first transmitted by Host C to when it is received at Host A? Assume that there is no queuing delay, and that node (router) packet- processing delays are also zero. b. Suppose Host C sends a message directly to Host D. The message is 10K bits long. What is the end-to-end delay from when the message is first transmitted by Host C to when it is received at Host D? Assume that there is no queuing delay, and that node (router) packet- processing delays are also zero
