Development

respond

It send the gluon-neighbour-info request and collect them together.

It will send UDP packetes by the multicast group ff02:0:0:0:0:0:2:1001 and port 1001.

modes.Nodes

It cached the Informations of the Nodes and will save them periodical to a JSON file. The current nodes are saved default under nodes.json.

websocketserver

One Instance is running under /nodes which send updates or new Nodes, which are collected by respond.

Issues

Later there should be also /aliases Websocket with Authentification to manage the aliases.json with the request for changes.
