SDN (Software Defined Networking) Nedir?<\/strong><\/h3>\n

Software Defined Networking (SDN)<\/strong>, geleneksel a\u011f altyap\u0131s\u0131ndan farkl\u0131 olarak, a\u011f kontrol\u00fcn\u00fcn yaz\u0131l\u0131msal bir merkezden y\u00f6netildi\u011fi<\/strong> yeni nesil bir a\u011f mimarisidir.

K\u0131saca SDN, a\u011f\u0131n kontrol katman\u0131n\u0131 (control plane)<\/strong>, veri iletim katman\u0131ndan (data plane)<\/strong> ay\u0131rarak y\u00f6neticilere a\u011f\u0131n tamam\u0131n\u0131 tek bir merkezden yaz\u0131l\u0131msal olarak kontrol etme imk\u00e2n\u0131 sunar.<\/p>\n
