- Transcribed Image Text 2. You are required to design IP addressing scheme for the Pantai Siring's branch for all floors using VLSM subnetting. You may use any private IP address class (10.0.0.0 to 10.255.255.255, 172.16.0.0 to 172.31.255.255 or 192.168.0.0 to 192.168.255.255). User group are as follows: a. Ground Floor- Administrator – 10 hosts b. 1* Floor - Lecturer – (Based on the last 2 digits of your Matric Number) For Example: B031910402 – 2 hosts only c. 2nd Floor - Student – 250 hosts d. 3rd Floor - Management – 80 hosts Explain in steps the calculations of your IP addressing scheme.Protocols at the Transport Layer's Core Both TCP and UDP are known by their respective acronyms. Justify the decision to implement TCP rather than UDP in an application. Please provide two (2) separate instances.Please help with as many of the following concepts and terms in regards to operating systems and networking: Socket Stream Client/Server Model Open end-to-end protocol for email POP3 vs IMAP FTP protocol DSN protocol Multiplexer vs Demultiplexer
- USING JAVA (Java Socket /TCP Programming) Create a chat/messaging application that has the following functionalities/features: Each user must log in to the system before he/she can perform actions/tasks. (passwords and usernames are stored in an XML file) Users must be allowed to send a broadcast message to all other users that are logged in. Any user must be allowed to send private messages to any of the established users.Both the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) are transport layer fundamental protocols. Please provide an explanation for why an application would be built to use TCP rather than UDP. Please submit two (2) further examples.Q2-A) Using the Class C network 200.18.55.0, subnet the network so that you will have 8 usable subnets and at least 14 hosts in each subnet. List the subnet address and the broadcast address for each of the subnets, as well as the usable host range available in the subnet. 1. Number of bits borrowed for the subnet. 2. Number of bits for hosts 3. Subnet Mask 4. Number usable hosts per subnet Subnet Number Subnet Address Broadcast Address Usable Host Range 1 2 3 4 5 6
- Subnetting.The Thulani Productions Company has been allocated the 172.30.32.0/20 block by one of the Internetservice providers. As the network administrator of the company, you are required to allocate validsubnets to the three office branches: Midrrand branch 450 users Centurion branch 100 users Brooklyn branch 200 users Use VLSM subnetting to accommodate all users for all mentioned office branches. For eachnetwork/subnet assigned to each office branch (group of users), specify the subnet mask,broadcast address and the valid host address range using the format below: Branch NameNumber of host bits neededSubnetSubnet mask (dot notation)Range of valid hostsBroadcast addressYou have been allocated a class A network address of 28.0.0.0. Create at least 20 networks and each network will support a maximum of 160 hosts using the subnet mask 255.255.0.0Assume 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)?
- Obtain the HTTP/1.1 specification (RFC 2616). Answer the following questions: a. Explain the mechanism used for signaling between the client and server to indicate that a persistent connection is being closed. Can the client, the server, or both signal the close of a connection? b. What encryption services are provided by HTTP? c. Can a client open three or more simultaneous connections with a given server? d. Either a server or a client may close a transport connection between them if either one detects the connection has been idle for some time. Is it possible that one side starts closing a connection while the other side is transmitting data via this connection? Explain.Subnets used: For the LAN addresses, you must use the classful network space 192.168.13.0. Use the VLSM design guidelines to subnet that classful network between R1, R2, and R3 based on the following requirements: R1 needs to support 29 hosts R2 needs to support 56 hosts R3 needs to support 11 hostsQ6: The web server in the below diagram cannot response to all requests come from different users in the network that caused delay in display the pages to the users, as network administrator suggest as solutions for the issues.
