node-p2p-chord is a light weight Chord protocol and algorithm library in JavaScript for a peer-to-peer distributed hash table (DHT). It is a sub-project of WoT.City and the underlying component of WoT.City software framework. The technical details can be found at WoT.City white paper.
To start a virtual node.
$ export HOST=192.168.0.3 ; the IP address for this Chord node to listening to
$ export PORT=8000 ; the port number for this Chord node to listening to
$ node node0.js ; start the the virtual node
To connect a subsequent node in order to join the existing p2p network.
$ export HOST=192.168.0.100 ; the IP address for this Chord node to listening to
$ export PORT=9000 ; the port number for this Chord node to listening to
$ node node1.js ; start a Chord node and join the existing node
In the node1.js file that you have to add join property for the connecting node.
// to connect to a subsequent node
server.start({
onmessage: onmessage,
join: {
address: '192.168.0.3',
port: 8000
}
});
To create a node and connect to a subsequent node. Add the join property to specify the existing p2p node.
var server = require('./libs/server');
/**
* Chord network.
*/
var onmessage = function(payload) {
};
/**
* Join an existing node.
*/
server.start({
onmessage: onmessage,
join: {
address: '127.0.0.1',
port: 8001
}
});
To create a new virtual node.
var server = require('./libs/server');
/**
* Chord network.
*/
var onmessage = function(payload) {
};
/**
* Create a virtual node (seed node).
*/
server.start({
onmessage: onmessage,
});
