Network Protocols

A network protocol is a set of rules that govern how data is exchanged between the devices in a network. Network protocols enable communication between devices that are located in different parts of the world. Consequently, they are critical in today's digital communications.

TCP MULTIPLEXING AND DEMULTIPLEXING
In the scenario below, the left and right TCP clients communicate with a TCP server using TCP sockets. The Python code used to create a single
welcoming socket in the server is shown in the figure (the welcoming socket itself is not shown graphically); code is also shown for the client sockets
as well. The three sockets shown in server were created as a result of the server accepting connection requests on this welcoming socket from the
two clients (one connection from the client on the left, and two connections from the client on the right).

In C/C++ network programming; create a simple web proxy that handles the connection between a client and server. I currently have been working on a client and server echoing each other from the geeks for geeks example but can't find much information in CODING up a web based proxy. I do understand the type of proxy to create but do not understand how to code one up in terms of client-proxy-server connection through https. The answer that I am looking for is how to create the web proxy in C. You can use the geeks for geeks example (client/server) or use one of your own.

Hello. I need help developing a C or C++ program that simulate an 8-port Ethernet switch. The switch initially has no knowledge about the hosts connected to each port. It learns frame addresses and stores-and-forwards the frames. The input text file "in.txt" contains information of the incoming frames, one frame per line. There are 4 pieces of data per line: frame ID, arrival port, frame source address,and frame destination address. The frames arrive at the switch in the order of which they appearin the input file. Destination address "X" indicates a broadcast frame. Thank you! ********************PLEASE YOUR CODE MUST BE COMPLETE, COMPILE AND EXECUTE**************** The output text file "out.txt" has 8 lines. Each line lists all the frames departing from each port, here is an example: "in.txt" contains 5 incoming frames:F1 P2 B--AF2 P6 D--CF3 P5 E--BF4 P7 F--DF5 P6 D--X"out.txt" should list the departing frames on each port:P1: F1 F2 F5P2: F2 F3 F5P3: F1 F2 F5P4: F1 F2 F5P5: F1…

Sockets are low-level networking interfaces between computers. Many programming languages come standard with socket libraries for creating socket connections. In this lab, we’ll study the usage of networking sockets in Python to write a custom client/server program. Client/Server source code as a ZIP or RAR file in D2L Word document outlining the description of your program. The word document should contain screenshots containing your name on the VM and reports of what’s occurring in them. Demonstrate your socket solution accomplishes the following: The client connects to the server Client and server successfully exchange messages Following the TCP stream in Wireshark Identifying the message sent in Wireshark Any additional functionality you created in your solution. please use python.
C Programming: Write a program that optionally accepts an address and a port from the command line. If there is no address and port on the command line, it should create a TCP socket and print the address (i.e. server mode). You can choose any port number for your server (>1024). If there is an address and port, it should connect to it (i.e., client mode). Once the connections are set up, each side should enter a loop of receive, print what it received, then send a message. The ping from the client should be sent before entering that loop to start the process. Otherwise both sides will sit and listen without getting anything. The message should be ping from the client and a pong from the server. In order to test this on one machine, you will need to run the same program twice (in two separate terminals). Run first in server mode, then run in client mode using the information printed from the server as your command line arguments. This is the output it must print out: Running…
JAVA You are requested to implement a “message buffer and response connector” class using Javaprogramming language. The following figure depicts a message buffer and response connectorclass, followed by detailed operations specifications. The message buffer and response connectorclass has three operations, send(), receive(), and reply().Your program should create two separate threads for testing your implementation, a producerthread, and a consumer thread. The producer thread sends a message having a structure (string,integer) – e.g., (add, 3) or (multiply, 7) - to a consumer thread via a message buffer and responseconnector. The consumer thread encapsulates a SimpleCalculation class that has two operations,add() and “multiply(). You should implement the SimpleCalculation class as well. When theconsumer thread receives a message from the connector, it extracts the message and then callsone of the operations on the SimpleCalculation class, depending on the message. For example,the…
Please do not use a python code already on the internet. The following code must be written in python for this HW assignment. I will provide a skeleten for the code and you must write some lines of code to satisfy the objective of the prorgram. you need to develop a web server that handles one HTTP request on at a time. the web server should acceptand parse the HTTP request, get the requested file from the server’s file system, and create an HTTP responsemessage consisting of the requested file preceded by header lines, and then send the response directly tothe client. If the requested file is not present in the server, the server should send an HTTP “404 NotFound” message back to the client. Dont need the hole code just right the information and code it to the skeleten pictures below.
