Consider a modern packet-switched network of three hops between a source host and a destination host, as shown in the figure below. source host —- packet switch —- packet switch —- destination host   The source host needs to send a message of  bits long to the destination host. The source host segments the message into smaller packets of 1000 bits each and sends the packets through the network. The destination then reassembles the packets back into the original message. Suppose the bandwidth of each link in the above figure is 1 Mbps. Ignore propagation, queuing and processing delays. How long does it take to transfer the entire message from the source host through the network to the destination host when message segmentation is used?
