A 64-kilоbyte messаge is tо be trаnsmitted оver two hops in а network as shown below. The network limits packets to a maximum size of 2 kilobytes, and each packet has a 32-byte header. The transmission lines in the network are error free and have a speed of 50 Mbps. Each hop is 1000 km long. How long does it take to get the message from the source to the destination? Assume, the signal travels at the speed of light (3×108 m/s); queueing and processing delays at the intermediate switch are negligible.
