ArcusNode aims to assist P2P networking with ease of extendability due to Javascript glue with NodeJS. ArcusNode is a standalone RTMFP implementation. We want to thank Cumulus, a standalone C++ implementation of the RTMFP Protocol and much more.

If you have an issue with ArcusNode, please use the Github issue tracker!
ArcusNode is still under heavy development and much work remains to be done. It covers the following features already:
- P2P Rendezvouz service
- NetGroups
- Remote Methods / Commands
- Authentication
- Plugins
ArcusNode runs on Node v0.5.5 and higher. To use ArcusNode as a service, get it from github and run:
$> node-waf configure build $> node service.js
You then should see something like:
Starting up ArcusNode RTMFP Service. Copyright (C) 2011 OpenRTMFP This program comes with ABSOLUTELY NO WARRANTY. This is free software, and you are welcome to redistribute it under certain conditions. (For usage help type "node service.js -h") ArcusNode RTMFP Service running at 0.0.0.0:1935
1935 is the default port for RTMFP communication and you should now be able to connect to the server, create groups and get peers connected.
If you run into problems building node on Cygwin, checkout https://github.com/joyent/node/wiki/Building-node.js-on-Cygwin-(Windows). If you consider using rebase, use both ./rebaseall and ./perlrebase.
As you can see in the service.js, it is very easy to use ArcusNode in your own project.
var ArcusNode = require('./lib/arcus_node.js');
var arcusService = new ArcusNode();
arcusService.run();
ArcusNode uses a mixture of Events and registered command callbacks. Events behave like known Node core events. Commands are called by a connected client through its NetConnection#call and can be registered on ArcusNode. Commands on the server behave almost exactly the same as described in the Flash Documentation, except that ArcusNode command callbacks always get the NetConnection which called the command as first argument, then the arguments from the Client.
At this moment, ArcusNode emits the following events:
- start
- stop
- handshake
- connect
- disconnect
- command
ArcusNode uses the Node EventEmitter API
Example for a connect event listener:
var ArcusNode = require('./lib/arcus_node.js');
var arcusService = new ArcusNode();
arcusService.on('connect', function(nc, obj){
console.log('Received a connection request for Connection ' + nc.id + ' with the properties', obj);
});
arcusService.run();
[todo]
Example for a command Client side:
var responder:Responder = new Responder(function(response) {
trace(response.what); //-> 'ArcusNode rocks!'
});
connection.call('sayWhat', responder, { name: 'ArcusNode' });
Example for a command Server side:
arcusService.onCommand('sayWhat', function(nc, obj){
return { what: obj.name + ' rocks!' };
});
The ArcusNode constructor takes a settings object with the following attributes:
.port Type: Integer Default: 1935 The port that ArcusNode will listen for UDP connections. .address Type: String Default: '' ArcusNode can be run on a specific interface if wanted. .logLevel Type: String Default: 'warn' Can be one of ['fatal', 'error', 'warn', 'info', 'debug']. .logFile: Type: String, path Default: '' If a path for a log file is specified, all logging will be written to that file. .manageInterval Type: Integer, seconds default: 60 The interval for the management cycle to do cleanup .connectionTimeout Type: Integer, milliseconds Default: 120000 The timeout for a NetConnection. The connections is dropped after the NetConnection was unused for that amount of time. .groupTimeout Type: Integer, milliseconds Default: 360000 The timeout for a NetGroup. The group is dropped afer there was no interaction for that amount of time. .serverKeepalive Type: Integer, milliseconds Default: 60000 The timeout before the server sends a keepalive command to the client. Should be less then connectionTimeout. .clientKeepalive Type: Integer, milliseconds Default: 60000 Will tell the client in what interval it should send keepalive messages .maxKeepalives Type: Integer Default: 3 How often to max keepalive the connection before dropping it.
To reach version 0.1:
- Add testing scripts and a Flash testing project
- Complete AMF reading/writing (70%)
