The All4Green architecture has been divided in three levels:
·         Level III: Contracts represents the components responsible for the contracts handling. A new type of contract (DC-Wide Contracts) was included during this first phase of the project.
·         Level II: Agents are active components that act on behalf of an actor of the All4Green ecosystem to help them achieve their objectives.
·         Level I: Connectors implements the logic required for the agents to communicate with the Energy Providers and Data Centres.
