Imagine you are a Network engineer in charge of setting up the network between UC Irvine and UC Berkeley. You are given two options for network configurations as given below: (a) A direct link from Irvine to Berkeley has a link of approximately 600 km with a propagation speed of 2* 10 m/s and a transmission rate of 1Mbps. (b) A link which is connected from Irvine to Santa Barbara with a distance of 220 km with a propagation speed of 2* 10 m/s and transmission rate of 4Mbps. Then, Santa Barbara to Berkeley with a distance of 500 km with a propagation speed of 2.5 * 108 m/s and transmission rate of 5Mbps. 1. Which option would you go with so that there is the least propagation delay? 2. Now, assume that packets are sent with a packet length of 1000bits. Find end-to-end delay for both configurations (ignore any processing and queuing delays). What option would you choose to have the least end-to-end delay?
