Distributed Communication Protocols with Docker

This project demonstrates the implementation of two fundamental communication protocols in a distributed system using Docker and Python: Unicast and Broadcast. The Unicast protocol enables one-to-one communication between nodes, while the Broadcast protocol allows a master server to send messages to multiple nodes simultaneously.

Project Structure

The project is divided into two main parts, each representing a different communication protocol:

UnicastProtocol

• Server: Manages client registrations and routes messages between nodes.
• Nodes (node1, node2, node3, node4): Connect to the server, send registration messages, and exchange messages with other nodes.

BroadcastProtocol

• Master Server: Broadcasts messages to all connected nodes.
• Nodes (node1, node2, node3, node4): Listen for broadcast messages from the master server and process them upon receipt.

Running the Project

The project is containerized using Docker, and each component runs in its own Docker container. To run the project, use the following commands:

UnicastProtocol

1. Start the server:

   docker run --name server --network proj1-distributed-network -v "$(pwd)/logs:/app/logs" proj1-distributed-network:latest python -u /app/UnicastProtocol/server.py

2. Start the nodes:

   docker run --name node1 --network proj1-distributed-network -v "$(pwd)/logs:/app/logs" proj1-distributed-network:latest python -u /app/UnicastProtocol/node1.py
   docker run --name node2 --network proj1-distributed-network -v "$(pwd)/logs:/app/logs" proj1-distributed-network:latest python -u /app/UnicastProtocol/node2.py
   docker run --name node3 --network proj1-distributed-network -v "$(pwd)/logs:/app/logs" proj1-distributed-network:latest python -u /app/UnicastProtocol/node3.py
   docker run --name node4 --network proj1-distributed-network -v "$(pwd)/logs:/app/logs" proj1-distributed-network:latest python -u /app/UnicastProtocol/node4.py

BroadcastProtocol

1. Start the master server:

   docker run --name server --network proj1-distributed-network -v "$(pwd)"/logs:/app/logs proj1-distributed-network:latest python -u /app/BroadcastProtocol/server.py
   docker run --name node1 --network proj1-distributed-network -v "$(pwd)"/logs:/app/logs proj1-distributed-network:latest python -u /app/BroadcastProtocol/node1.py
   docker run --name node2 --network proj1-distributed-network -v "$(pwd)"/logs:/app/logs proj1-distributed-network:latest python -u /app/BroadcastProtocol/node2.py
   docker run --name node3 --network proj1-distributed-network -v "$(pwd)"/logs:/app/logs proj1-distributed-network:latest python -u /app/BroadcastProtocol/node3.py
   docker run --name node4 --network proj1-distributed-network -v "$(pwd)"/logs:/app/logs proj1-distributed-network:latest python -u /app/BroadcastProtocol/node4.py

2. Broadcast a message from the master server:

   docker exec server python /app/BroadcastProtocol/broadcast_message.py
