- • 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 Bits4 LANS are connected to a router (R1) with each LAN compares of several hosts connected to a switch. Each LAN cotains the following number of hosts (end devices and the gateway interface), • LANI à 30 Hosts • LAN2 à 15 Hosts • LAN3 à 20 Hosts • LAN4 à 3 Hosts You have received the address space 200.16.1.0/24. Use the address space to create a subnetting scheme of four subnets with equal size in a way to accommodate the number of hosts required. Consider the following points in your answer, / Explain the procedure of your subnetting scheme / Highlight the suitable prefix and the subnet mask / Highlight the number of wasted hosts in each subnet after determining the most suitable prefix / Use the table below to provide the subnet details for each LAN Subnet Address First Host address Last Host address Broadcast address 1 LANI 2 LAN2 3 LAN3 4 LAN4Assume a client is connected to the server and has already received an HTML webpage. It reads the webpage, and it now needs to get 3 new files, File A is 5 MB file B is 1 MB and file C is 1 KB. The client requests the files in the order A B C. The link has an RTT (round trip time) of 0.5 seconds and a bandwidth of 8 Mb/s(Megabits per second) (or 1 Megabyte per second). The client can reuse the open connection if the protocol allows it to. For all parts of this problem ignore header sizes, and start the timer when the client sends How long does it take to get file C under HTTP 0? How long does it take to get file C under HTTP 1 (assume the browser does not support pipeling)? How long does it take to get file C under HTTP 2 assuming a frame size of 1 KB and no server push? What event would make HTTP 3 faster than HTTP 2 for this use case (ignore TLS)?
- 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. IP Address 172.16.0.0 FO/O S//0/1 FO/O Sales Administrative FO/1 185 Hosts 30 Hosts SO/0/0 Marketing 50 Hosts,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?Computer Science Networks and should be done in C language. Create a UDP client and server program that not only is able to locally transfer files but it gives the client the ability to send multiple copies of the file to multiple servers. Once the server program is initiated, it waits until it receives client packets. It then reads and saves the payload of the packets. The client reads a file from the disk and sends it to each server over a UDP socket by breaking the file up into mtu-byte sized packets. Client needs to be concurrent in sending the packets to all of the servers using threads
- 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?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 signi cant bits are used as a network ID, and the 16 least signi cant bits are used as a host ID. However, the host ID cannot be all 0's or all 1's. How many hosts (i.e., host IDs) can there be on a class B network?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 = ms
- Task2: In packet switching technology the packet size is an import parameter when it comes to efficiency and reducing the network latency. Let us assume a network which consists of a sender host and a receiver host at nh hops faraway from each other's (nh-1 routers R). s>R>R> ...>S. If we assume that all links have a bit-rate B bps and originally the message to be send from the sender to the receiver is of size L bits. 1) Give the formula to compute the network latency if we assume circuit switching (switching time per switch is s seconds). 2) Same as in 1) but we assume packet switching with packet size p bits. 3) From 2) drive the best packet size p which give the best performance (minimum network latency). Hint. One way to find out the minimum of a function f is to find its derivative f'(0). 4) Verify your result by providing prove example.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 0's or all 1's. How many hosts (i.e., host IDs) can there be on a class B network?Refer to the exhibit. There are 3 LAN networks in the diagram. The network address given is 192.168.1.0/24. Your task is to do subnetting to support 62 hosts for each network.
