New York, the destination host, is 5 hops away from Minneapolis, the source, i.e. there are 4 intermediate routers: Minneapolis R1 R2 R3 R4 New York. The distance between any two adjacent nodes is 250 kilometers (km). The signal propagation speed is 2.5 105 km per second. The message size is 2Mbits (1M = 106 ) The maximum packet size is 100 Kbits (1K = 103 ). The header size is negligible. Note for packet switching the message should be divided to packets, each of which cannot exceed the maximum packet size. The transmission speed of each link is 100Mbps). The circuit setup time is 0.5 second for the case of circuit switching. The processing time for routing & forwarding decision at each node can be ignored. Please answer the following questions. (a) ( The end to end delay in delivering the message using circuit switching. (b) The end to end delay in delivering the message using packet switching. (c) (5 points) Will the delays calculated in parts (a) and (b) alter if Minneapolis was the destination and New York the source? Justify your answer.
