Question:Now suppose that the message is segmented into 20 packets, with each packet being 1,000,000 bits long. How long does it take to move the first packet from source host to the first switch? When the first packet is being sent from the first switch to the second switch, the second packet is being sent from the source host to the first switch. At what time will the second packet be fully received at the first sw

Question:Now suppose that the message is segmented into 20 packets, with each packet being 1,000,000 bits long. How long does it take to move the first packet from source host to the first switch?
When the first packet is being sent from the first switch to the second switch, the second packet is being sent from the source host to the first switch. At what time will the second packet be fully received at the first switch?

Exercise 3: In modern packet-switched networks, including the Internet, the source host segments long, application-layer messages (for example, an image or a music file) into smaller packets and sends the packets into the network. The receiver then reassembles the packets back into the original message. We refer to this process as message segmentation. For this exercise we will use the network architecture provided in the figure below, were Rs, Rc and R; for i = {1,2,3,4}, the transmission rates of the server link, client link and intermediate network links. Consider a message that is 20 · 106 bits long that is to be sent from client to server. Ignore propagation, queuing, and processing delays. Suppose that links R; for i = {1,2,3} in the figure are 20 Mbps, that Rs, Rc are 30Mbps and that R4 are 10Mbps. Client R2 Server R, R, Rc Rs R, 4
