Question

UDP Echo Application
A UDP Echo program is a simple network application that demonstrates the basic
principles of UDP communication. In this program, a server listens for incoming UDP
packets from clients, and when it receives a packet, it echoes (sends back) the same
packet to the client. The client sends a message to the server, and the server returns the
same message. It's often used for testing network connectivity and understanding the
fundamentals of UDP communication.

(Answer the following question using python)

Implement both the server and client components of this UDP Echo program while
adhering to the features outlined below. Please ensure that your implementation follows
good coding practices and provides clear prompts and feedback to the user, making it
user-friendly and robust. Please refer to the class example to guide your implementation.

1) UDP Echo Server

Receiving and Displaying Messages: The UDP Echo server should be able to
receive messages sent by clients. For each received message, it should display the
address from which the message was received and the content of the message.
Echoing Messages Back: After receiving a message, the server should echo it
back to the client who sent it. It should print the message that was sent and the
address to which it was sent.

2) UDP Echo Client

User Input: The UDP Echo client should interact with the user. It should ask the
user to input a message that they want to send to the server and specify the
number of times they want to send this message.
Sending Messages: Using a Python loop, the client should send the user-specified
message the specified number of times to the server's IP address and port.

The pictures below are class example.

Server side of a client-server application using UDP
This is a Python program for a simple UDP server. It sets up a server that listens on a specified port for incoming messages, converts those messages to uppercase,
and then sends the modified messages back to the clients.
from socket import *
# Create a socket and set the server port
serverPort = 12000
serverSocket = socket (AF_INET, SOCK_DGRAM)
# Bind the server socket to any IP address and the specified port
serverSocket.bind(('', serverPort))
print("The server is ready to receive messages...")
while True:
# Wait for a message to arrive
message, clientAddress = serverSocket.recvfrom (2048)
# Decode the message, convert to uppercase, and send it back to the client
modified Message = message.decode().upper()
serverSocket.sendto(modified Message.encode (), clientAddress)
The server is ready to receive messages...

Client side of a client-server application using UDP
This Python code snippet is a simple example of a UDP (User Datagram Protocol) client that communicates with a server. It sends a message to the server, receives a
modified response, and then prints the modified response.
from socket import *
serverName = 'localhost' # Replace with the actual server hostname or IP address
serverPort = 12000
client Socket = socket (AF_INET, SOCK_DGRAM)
message=input('Input lowercase sentence: ') # Use input() for Python 3
client Socket.sendto (message.encode(), (serverName, server Port))
modified Message, serverAddress = client Socket.recvfrom (2048)
print(modified Message.decode()) # Use parentheses for print in Python 3
client Socket.close()
Input lowercase sentence: this
