Computer Science Assume the length of each message is L=5, the access link has a speed of X=180 Mbps, and there are B=6 messages per second on average. What is the total average delay for receiving a message when no cache is used, i.e., the sum of LAN delay, access delay, and internet delay? Give your answer in milliseconds.
Assume that there is a shared connection (for example, an Ethernet bus) with a speed of 1 Mbps. How much time (in microseconds) is required to send a frame with a length of 1000 bits over this link?
Assume a 10Mbps Ethernet has two nodes, A and B, connected by a 360m cable with threerepeaters in between, and they each have one frame of 1,024 bits to send to each other. Further assumethat the signal propagation speed across the cable is 2*10^8 m/sec, CSMA/CD uses back-off intervals ofmultiples of 512 bits, and each repeater will insert a store-and-forward delay equivalent to 20-bittransmission time. At time t=0, both A and B attempt to transmit. After the first collision, A draws K = 0and B draws K = 1 in the exponential back-off protocol after sending the 48bits jam signal. a. What is the one-way propagation delay (including all repeater delays) between A and B inseconds? At what time is A's packet completely delivered at B? b. Now suppose that only A has a packet to send and that the repeaters are replaced with switches.Suppose that each switch has an 8-bit processing delay in addition to a store-and-forward delay.At what time, in seconds, is A's packet delivered at B?

Use again the network architecture provided in the figure above, were RS, RC and Ri for i = {1,2,3,4}, the transmission rates of the server link, client link and intermediate network links. Consider a message that is 60 · 106 bits long that is to be sent from client to server. Ignore propagation, queuing, and processing delays. a.Now assume that Rc = 60Mbps, Rs = 40Mbps, R1 = R3 = 30Mbps, R2 = 10Mbps and R4 = 20Mbps. Suppose that the message is segmented into 6000 packets, with each packet being 10,000 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? b) How long does it take to move the file from source host to destination host when message segmentation is used if path R3, R4 is chosen?
This elementary problem begins to explore propagation delay andtransmission delay, two central concepts in data networking. Consider two hosts, Aand B, connected by a single link of rate R bps. Suppose that the two hosts areseparated by m meters, and suppose the propagation speed along the link is smeters/sec. Host A is to send a packet of size L bits to Host B. g. Suppose ? = 2.5?108, L=1500 bytes, and R=10 Mbps. Find the distance m sothat ????? equals ??????.

Topic: Network Delay Assume two hosts, A and B, that are linked by a single link with a rate of R bps and are spaced m meters away from one another. A packet of size L bits is being sent from Host A to Host B. Suppose that the propagation through the connection is occurring at s meters/second. (Answer the following question while showing work) 1) Assuming that processing and queuing delays are 0, provide an expression for end-to-end delay in terms of m, s, L, and R. 2) Where is the final bit of the packet at time t = dtrans if Host A starts transmission at time t = 0?
