Broker Discovery
In order for DSA to be seamless, there has to be a way to discover brokers. The Broker Discover Protocol is a very simple solution to this problem.
All communications use IP address 239.255.255.230 and port 1900.
All packets are just a textual message. There is no need for a special packet structure. Discovering brokers is a very simple and quick process.
The message format is TYPE [ARGUMENT], where type is required and argument is optional.
To discover brokers on the local network, the DISCOVER message is used.
DISCOVER
For a broker to announce itself, it sends a BROKER message with the connection URL as the argument. It should send it in a unicast message to the address of the issuer of the DISCOVER message. Multiple brokers on a given IP address with a different port are fine.
BROKER http://192.168.2.53:8080/conn
Links should connect to every broker it has discovered. This makes it easy for users to whitelist links once they are connected.
