+    Una semplice applicazione che effettua una comunicazione tra più container attraverso un ring logico di comunicazione tra 3 (o più) diversi container che si trovano 
+    su un singolo host. La comunicazione è token-based. Il client non deve fare altro che scegliere il servizio che immetterà il token all'interno della rete
+    e il numero di salti che il token effettuerà all'interno di essa. Riceverà un token di risposta nel caso tutto sia andato a buon fine dall'ultimo container ad aver
