Что такое ASN?

Автономная система (AS) - это совокупность соединенных сетей, которые функционируют в рамках общего административного домена и делятся политикой маршрутизации. Каждая AS идентифицируется уникальным номером автономной системы (ASN), который используется для обмена информацией маршрутизации с другими AS. AS могут контролировать поток трафика через сети и фильтровать нежелательный трафик.
