Orchestrator -> Registry : Query available nodes & capabilities

Registry --> Orchestrator : Return eligible nodes



Orchestrator -> Node : Select participants\n(Federation Group Selection)

Orchestrator -> Node : Distribute initial global model



loop Local Training

    Node -> Node : Train local model on private data

    Node -> Aggregator : Send model updates (weights/gradients)

end



Aggregator -> Aggregator : Aggregate model updates securely

Aggregator -> Orchestrator : Send aggregated global model

Orchestrator -> Node : Redistribute improved model



alt Node with limited resources

    Orchestrator -> Node : Assign smaller training load

end



alt High connectivity nodes

    Orchestrator -> Node : Prioritize for synchronization

end
