Distributed Hash Table (DHT) Project using Chord Algorithm

Overview

This project is an implementation of a Distributed Hash Table (DHT) using the Chord algorithm. It efficiently distributes and manages data across a network of nodes, ensuring availability and fault tolerance in a decentralized way. The system handles dynamic network changes, allowing nodes to join and leave without disruption.

Getting Started

Setting Up the Environment

Before launching nodes and the client, create and activate the virtual environment (install necessary packages):

virtualenv -p python3.8 env
python -m pip install grpcio
python -m, pip install grpcio-tools
source env/bin/activate

Launching a Node

To launch the initial node in the network: python node.py 127.0.0.1:9092

This starts a node at IP address 127.0.0.1 and port 9092.

Joining a New Node

To add a new node to the DHT network: python node.py 127.0.0.1:9094 127.0.0.1:9092

This initiates a new node on IP address 127.0.0.1 and port 9094, connecting to the node on port 9092.

Launching the Client

To interact with the DHT network:

python client.py

Client Commands

• Connect the client to a bootstrap node：bootstrap_server <ip:port>
• Add Key-Value Pair: set <key> <value>
• Delete Key-Value Pair: del <key> <value>
• Retrieve Value by Key: get <key>
• Exit a node from the system: stop

Replace <key> and <value> with the desired key and value for your operations.
