- Function: A client can chat with the server, with input in the screen, and output the other side's replies. No GUI needed. Keypoints: TCP socket is used for both sides. Both sides open two sockets, one for sending, while the other for receiving. IN JAVA OR C/C++ with both client code and server codeQ2.Recently QUIC protocol is suggested. a. Elaborate on the advantages of QUIC through an example scenario. b. The standard protocols, like TCP, UDP and HTTP, are implemented in various languages. For example, Java language has ServerSocket() class for TCP server. Does the QUIC protocol is supported in any language? I mean its library is available. If yes, please explain its working. And run a simple QUIC client program, even if this program is available over the Internet. c. List the servers supporting QUIC protocol, if they exist.CIS269 **SEE ATTATCHED PICS FOR BEST TRANSLATION** Packet Translation Lab Break down the following IP datagram into its individual fields, listing the value of each.

- Write a Java program to create a TCP Socket program to receive an input message from client socket, reverse the input message and send it back to the client. Note that the program should have the comments embedded in it to explicitly explain why that code is being used. Explain in detail the client process and the server process with reference to the code given by you for this task.d) State all the random access protocols and controlled access protocols. Explain why collision is an issue in random access protocols but not in controlled access protocols.Description: You are required to implement a server program that responds to both TCP and UDP requests from the corresponding clients. The service provided by the server is simply a substitute cipher/cryptosystem. The cipher replaces one character to another based on some key. The input message (plaintext) can be of any size but composed only of small-letter (abcdefghijklmnopqrstuvwxyz). The output (ciphertext) has the same size and composed also of small-letter characters. The key is limited to 7 characters (also small-letter). You need to treat each digit as a number according to its position in the alphabet. For example, a=0, b=1, …,z=26. To encrypt a message, you add a plaintext character with the corresponding key character (mod 26). The key might be repeated to match the length of the plaintext message. In the decryption, you subtract the corresponding key character from the ciphertext character (mod 26). Again the key might be repeated as necessary. For example, if the…

(5 Marks)Can anyone help me with basic client-server interaction using TCP sockets in network programming in c code that includes csapp.c and csapp.h. and a text file of the student record that include first name, last name, age, major, and graducation year. The ideas is have 4 choice: Add record, Search Age Range, Search graducation year, and Terminate. In opition 1, it should collect all the data to the text file, in opition 2, it should search for age range from the text file. in opition 3, it should search the graducation year from the text file and if the year is not there it should print record not found. And opition 4, the client should close the connection and terminate. studentRecord.txt: John,Doe,24,Computer Science,2023Jane,Doe,22,Mechanical Engineering,2020Charles,Babbage,21,Math,2022George,Bool,25,Math,2023Marie,Curie,26,Chemistry,2023 I know this isn't enough but I want to understand about the client-server interaction using socket interface. So please try to make it simple…Java Network protocol programming You are required to program a client and a server application using TCP based socket. The client should send a message to the server of the following format Operation operand1 operand2 Where Operation is either add, subtract, multiply, or divide. Operand 1 and Operand2 are two integers. The server should distingues the required operation and perform it over the two operands. The result of carrying out this operation should be sent back to the client. The client should present the result to the user. The work have to be within a group of two. One student should focus on implementing the client side while the other should focus on the server. Both student should fully understand and be able to modify and explain both sides the client and the server. Rubrics are as follows 1- Well organized commented out code. : 2- Correct implementation of the protocol described above. 3- Clear and easy to use interface with the user. 4- Fully running code.
- 34. What is the “half-duplex close” case in TCP?Explain what this rule does: alert tcp any any -> 192.168.1.0/24 80 (content:”|A1 CC 35 87|”; msg:”accessing port 80 on local”).- Consider another carelessly written Web application, which uses a servlet that checks if there was an active session, but does not check if the user is authorized to access that page, instead depending on the fact that a link to the page is shown only to authorized users. What is the risk with this scheme? (There was a real instance where applicants to a college admissions site could, after logging into the Web site, exploit this loophole and view information they were not authorized to see; the unauthorized access was however detected, and those who accessed the information were punished by being denied admission.)
