+ * + *

These are all the messages sent from the engine to the client. + * Communication takes place over two distinct bands: control band and + * notification band.

+ *

The control band is where clients send commands, and receive a simple + * response, either OK or an error.

+ *

All notifications of engine state (ie new nodes) are sent over the + * notification band which is seperate from the control band. The + * reasoning behind this is that many clients may be connected at the same + * time - a client may receive notifications that are not a direct consequence + * of some message it sent.

+ *

The notification band can be thought of as a stream of events representing + * the changing engine state. For example, It is possible for a client to send + * commands and receive aknowledgements, and not listen to the notification band + * at all; or (in the near future anyway) for a client to use UDP for the control + * band (for speed), and TCP for the notification band (for reliability and + * order guarantees).
