Protocol core-GUI¶

This page describes the protocol used by D-LAN for network communication between core and GUI.

See source:application/Protos/gui_protocol.proto for message details.

• There's can be many GUI connected to one core. This is not a goal to achieve but it can be easily done with the chosen protocol.
• All communication is made on a single TCP connection which is never closed.

Message types¶

There is three types of message.

• Core -> GUI State : The whole state is periodically sent to the GUI, for example each second.
• Core -> GUI Event : Some events can occurs asynchronously like a new chat message or a new log entry.
• GUI -> Core Command : The GUI can send commands to the Core to tell it what to do like download this or browse that. It may or not have a respond from the Core depending of the message.
