Yayın Ağları(Broadcast Networks), bir bilgisayarın kendisi ile aynı ağ üzerinde bulunan diğer tüm bilgisayarlara veri göndermesini sağlar. Kanal ataması(channel allocation) yapılmış bir gönderici, ağ(network) üzerindeki tüm alıcılara mesaj gönderir. Mesaj, Veri Bağı Katmanında(Data Link Layer) frame adı ile anılır. Ağ üzerinde bulunan tüm alıcılar frame' in varış adres bölgesine bakarak, paketin kendilerine ait olup olmadığını denetler. Link katmanında varış adres MAC(Media Access Control) adresi olarak bilinir. Alıcılar, gelen frame'i kendilerine ait değilse ihmal eder(ignore, discard) ve hiç bir reaksiyon göstermezler.
