-- n Clients       (STM32, Aruino, Rapberry Pi)
-- 1 Broker        (en ligne, serveur)
-- m Appilications (PC, Smartphone)
-
-### Modèles
-
-Topic
-- Des queues parallèlles de messages.
-- Permet aux clients d'échanger des informations d'une sémantique spécifique.
-
-Session
-- Une session qui identifie l'ensemble des topics et la séquence des messages reçus.
-- Toutes les communications client / serveur se feront par sessions.
-
-Subscriptions
-- Contrairement aux sessions, un abonnement attache un client à un topic.
