Consider a message $2$ MB long that is to be sent from Source Host to Destination Host, which are separated by two Routers in between. Suppose each of the three links in this path has data rate of $2$ Mbps$.$ Ignore propagation, queueing and processing delays. Consider sending the message without message segmentation. How long does it take to move the message from Source host to the first Router? Keeping in mind that each router uses a store$-$and$-$forward packet switching, what is the total time to move the message from Source to Destination?
