Cos'è un ASN?

Un Sistema Autonomo (AS) è una collezione di reti collegate che operano sotto un dominio amministrativo comune e condividono politiche di routing. Ogni AS è identificato da un numero univoco di Sistema Autonomo (ASN), che viene utilizzato per scambiare informazioni di routing con altri AS. AS può controllare come il traffico fluisce attraverso le reti e quindi filtrare il traffico indesiderato.
