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…
b) Assuming two 1 Mbps Ethernet LANS (LAN Y and LAN Z) are connected by a bridge. An application in LAN Y sends 32 packets per second to LAN Z. Each IP packet has total size of 1480 bytes (excluding the preamble and cyclic redundancy check (CRC)). Assuming the inter-frame gap (IFG) is 9.6us, determine: i) The total size of the frame. ii) The time taken for the frame to send through LAN Z.
An IP address can be written as a 32-bit number. For a class B network, the two most significant bits are set to 10. The 16 most significant bits are used as a network ID, and the 16 least significant bits are used as a host ID. However, the host ID cannot be all O's or all 1's. How many hosts (i.e., host IDs) can there be on a class B network? Type your answer.
Do not give me irrelevant answers please. I want correct explanation. Else i will report it.

An Internet user would like to transfer a message from his computer (host A) to another computer (host B). The size of the message passed to the IP layer is 3800 bytes. The datagram(s) carrying the message will have to cross two routers (R1 and R2) and 3 networks (NET1, NET2, and NET3) as described in the above figure. Each of these networks has a specific MTU (for example the MTU of network 1 is 1500 bytes. MTU here stands for Maximum Transmission Unit, the largest data that a frame can carry). Fill the table with the IP datagram(s) needed right after passing through NET3 (no need to show your fragmentation for N1 or N2). Assume a 2-byte options in the header. Show all your details (for partial points in case your numbers are incorrect). NET1 MTU=1500 R1 NET2 MTU=640 R2 NET3 MTU 1500 V BIU Fragment # Format Offset Flag (3 bits) Data Length Total Length ...
In the above network diagram, IP and MAC addresses are given for network nodes. Suppose Host1 (Shahid) sends a datagram to Host2 (Khalid). What IP and MAC addresses (source and destination) will be written in IP and Data link layer headers respectively, for the following intermediate points from Host1 to Host2?a) Host1 to Router1 (R1)b) Router1 to Router2 (R2)c) Router2 to Host2
