Communication Infrastructure Project

This project is part of the Communication Infrastructure course at CIn/UFPE. It is divided into three main phases, each building upon the previous one. The project explores various aspects of network communication, focusing on UDP and the RDT 3.0 protocol.

Phase 1: File Transmission with UDP

• Objective: Implement file transmission using UDP in Python.
• Details:
  • Use the Socket library to send and receive files of at least two different types (e.g., .txt and images).
  • Files are sent from the client, stored on the server, and returned to the client.
  • Implement packet fragmentation for files larger than 1024 bytes and ensure reassembly at the receiver.

Phase 2: Reliable Data Transfer with RDT 3.0

• Objective: Implement a basic reliable data transfer protocol using RDT 3.0 over UDP.
• Details:
  • Use the code from Phase 1 and enhance it to handle reliable transmission using RDT 3.0.
  • Simulate random packet loss and timeouts to demonstrate the protocol's reliability.
  • Display each step of the algorithm execution in the command line for better understanding.

Phase 3: Accommodation Reservation System

• Objective: Develop a client-server system for managing accommodation bookings using the concepts from previous phases.
• Details:
  • Implement a command-line interface for users to manage accommodations and bookings.
  • Ensure simultaneous operation for multiple clients without interrupting the service.
  • Incorporate the RDT 3.0 protocol for reliable communication.
  • Deliver a video demonstration explaining the code and showing the system in action.

Installation and Setup
