Frame Relay Nedir?
Frame Relay tüm dünyada yaygın olarak kullanılan paket anahtarlamalı bir teknolojidir. Leased Line'a göre daha ucuz olduğu için daha çok tercih edilen bir haberleşme teknolojisidir. Frame Relay bağlantısı için en yakın Türk Telekom Frame Relay Switch'ine yüksek bant genişliğine sahip modem ve Router ile bağlanmanız gerekmektedir. Anahtarlanmış paket teknolojisine dayanan Frame Relay veriyi küçük paketlere bölerek gönderir. Bu paketler gönderilecek olan adresi, gönderenin adresini ve orijinal mesajın bir parçasını içerir.
