Qu'est-ce qu'un ASN?

Un système autonome (AS) est un ensemble de réseaux connectés qui fonctionnent sous un domaine administratif commun et partagent des politiques de routage. Chaque AS est identifié par un numéro de système autonome (ASN) unique, qui est utilisé pour échanger des informations de routage avec d'autres AS. AS peut contrôler comment le trafic circule à travers les réseaux et filtrer le trafic non désiré.
