Exercise 5.2.6 Use your textbook and the Internet to determine the communication steps in an ARP Request and Response. What steps are involved and how is each message sent ( broadcast to all devices or unicast to a single device)? 1. Based on the interface and the forwarding IP address, ARP consults the appropriate ARP cache for an entry for the forwarding IP address. If an entry is found, ARP skips to step 6. 2. If the entry is not found, ARP builds an ARP Request frame containing the MAC address of the interface sending the ARP Request, the IP address of the interface sending the ARP Request, and the forwarding IP address. ARP then broadcasts the ARP Request using the appropriate interface. 3. All hosts receive the broadcasted frame and the ARP Request is processed. If the receiving host's IP address matches the requested IP address (the forwarding IP address), its ARP cache is updated with the address mapping of the sender of the ARP Request. If the receiving host's IP address does…
6. Delays. A user in Madagascar, connected to the internet via a 100 Mb/s (b-bits) connection retrieves a 250 KB (B-bytes) web page from a server in Tokyo, where the page references three images of 500 KB each. Assume that the one-way propagation delay is 82 ms and that the user's access link is the bandwidth bottleneck for this connection. a. Approximately how long does it take for the page (including images) to appear on the user's screen, assuming non-persistent HTTP using a single connection at a time? (For this part, you should ignore queueing delay and transmission delays at other links in the network) How long does it take if the connection uses persistent HTTP (single connection)? b. c. Suppose that user's access router has a 4 MB buffer (B-byte) on the link from the router to the user. How much delay does this buffer add during periods when the buffer is full? d. Assume a cache rate of 45% on the information received by the user in Madagascar from the Tokyo server. How does…
9. Consider the given scenario where Host A wants to send a file to host B. Calculate the end to end delay between Host A and Host B, when the propagation speed at each link is approximately 2x108 m/sec, and the processing and queuing delays at the router are 10 msec and 25 msec, respectively, when: (a) File size is 1500 bytes and only one packet is sent. 4 (b) File size is 6000 bytes and four packets are sent (1500 bytes in each packet).

2. Consider a slotted TDM hierarchical network in which there are 8 computers sharing a 10 Mbps channel to a router R1, sending packets to R1 which must all be forwarded by R1 over an outgoing link (called the MAN link), as shown in Figure 1. Computers A-H always have packets waiting to be sent, so no timeslot on the shared LAN is idle. Ignore the propagation delay on the LAN. The MAN link outgoing from R1 is a 100 Mbps link. The network layer protocol in use has a PDU with exactly 40 bytes of header and exactly 200 bytes of payload (SDU). The DLC layer protocol in use on the LAN has a PDU with exactly 40 bytes of header and 20 bytes of trailer. The DLC layer protocol in use on the outgoing link from R1 has a PDU with 40 bytes of header and no trailer. The physical layer does not impose any bit overhead in either channel.

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. c.How long does it take to move the file from source host to destination host when message segmentation is used and both path R1, R2 and path R3, R4 are used? How many packages should be routed from path R1, R2 and how many from path R3, R4 in order to maximize the use of the network? d.What is the end to end throughput if path R1, R2 is used, and what if path R3, R4 is used? What is the total throughput from client to server (if both paths are being used at the same time)?
