Homework – Chat Application

1. Implement a Chat Application (5 points)

Clients connect to the server using the TCP protocol.
The server receives messages from each client and broadcasts them to all other clients (include the client’s ID/nickname with each message).
The server must be multithreaded – each client connection should have its own thread.
Pay attention to proper thread management.

2. Add an Additional UDP Channel (3 points)

The server and each client should open an additional UDP channel (use the same port number as for TCP).
After entering the command U on the client side, a message is sent via UDP to the server, which then forwards it to the other clients.
The message should simulate multimedia data (for example, you can send ASCII Art).

3. Implement the Above Feature Using Multicast (2 points)

This should not replace the UDP channel, but should be available as an alternative option (use the command M).
Multicast should send the message directly to all clients using a group address (the server may, but does not have to, receive the message).
