- 4. The original HTTP protocol used TCP/IP as the underlying protocol. For each page, graphic, or applet, a separate TCP connection was constructed, used, and terminated. This caused several problems: one referred to as the elephant and mice problem and two aspects of connection overhead. Describe both problems. Why were separate connections used? Would UDP rather than TCP be a good alternative? What solution would you propose to these problems to improve HTTP performance?Give an example of a situation in which multicast addresses might be beneficial.Assignment 5: Both TCP and UDP are widely used IP transfer layer protocols. For applications requiring reliable transfers, TCP is generally preferred, while applications that value throughput more than reliability are best served using UDP. Most TCP/IP stacks provide both protocols, so the application can use whichever transfer protocol is more appropriate, even changing from one to the other as desired. Rather than rely solely on TCP, the network system developer might want to investigate the trade-offs related to use of UDP. Based upon the analysis list out why Some TCP/IP Applications Use UDP?
- • IPV6 addresses use 128 bits to represent an address which includes bits to be used for subnetting. The second half of the address (least significant 64 bits) is always used for hosts only. Therefore, there is no compromise if we subnet the network. Use the Figure below to Create five subnets using route prefix 2001:db:acad::/48 (1 Marks) Routing Prefix Subnet ID Interface ID 48 Bits 16 Bits 64 BitsProvide an example of a protocol at each of the TCP/IP model layers, for example that you have used in the above. Also give an example of overhead added in each of these protocols, e.g. a field in the protocol header. If possible, provide information on the maximum size of each packet, and the size of the header, of each of these example protocols.MC9: In wireless LAN communication, MACA is widely used. In this protocol, in order to avoid collision, a sender can send sender is granted the privilege to send a frame to the receiver only after it receives request signal to a receiver.

- Suppose we have a web page which contains 10 objects including: a html main file, 8 jpg image, and a .mp3 background music. For simplicity, assume each of the 10 objects has a size of 4 Kbits and that each object can be completely transferred in one TCP packet. Furthermore, assume the round-trip time between the server and client is RTT= 250 ms, and the download rate is 1 Mbps. What will be the time it takes to complete transferring the web page running in the non-persistent mode? Total delay = msShow the shortest and original (unabbreviated) form of the following addresses. a. 2340:0000:0000:0000:0000: 119A:AOO1:0000 0000:0000:0000:2340:0000:0000:0000:0000 0::0 0:AA::0 Is it possible that a host with IPv6 can communicate with a host of IPv4?

ARP is used for: O packet path determination O finding of a mapping IPV6 → MAC address O finding of a mapping IPV4 → MAC address O finding of a mapping IPV4 → TCP addressConsider a datagram network using 32-bit host addresses, i.e., IP addresses range from 0 to 255. Suppose a router uses longest prefix matching and has the following forwarding table: For each of the four interfaces, please give the associated range of destination host address and the number of addresses in the range.Design a classfull network addressing scheme that will supply the minimum number of hosts per subnet, and allow enough extra subnets and hosts for 25% growth in all areas.
