Какво е ASN?

Автономна система (AS) е колекция от свързани мрежи, които функционират под общо административно домейн и споделят политики на маршрутизация. Всяка AS се идентифицира с уникален номер на автономна система (ASN), който се използва за размяна на информация за маршрутизация с другите AS. AS може да контролира как трафикът преминава през мрежите, а след това да филтрира нежелания трафик.
