Q3. Consider a simple network as follows: 20P bits of data need to be sent from node A, through node B, to node C. Link A-b and link B-C are identical. The link bandwidth is R bps. The link speed is s mps. Each link is of length D meters. Suppose the packet header containing necessary information to deliver any amount of data from A to C is P bits. Consider queuing and processing delays are negligible. a) If we send all the 20P bits data in one packet, calculate the delay for all the data to arrive at C. b) Calculate the total delay for the data to arrive at C if the user data is sent in two equal sized packets.
