The Ditto Protocol defines a JSON based text protocol for communicating with digital twins and the actual physical devices they mirror.
It defines several commands both the actual device and the digital twin are able to understand.
The communication pattern is defined by the Ditto protocol and shown in the next section.
The typical communication pattern when interacting with a digital twin or the actual device using the Ditto Protocol
is composed of multiple correlated Protocol messages.
Therefore, each Protocol message contains a
correlation-id which can be used to associate related Protocol messages.
The Signals chapter already describes the basic communication pattern of commands, responses, events and announcements.
