Ein Content Delivery Network (CDN), oder auch Content Distribution Network genannt, ist ein Netz regional verteilter und über das Internet verbundener Server, mit dem Inhalte – insbesondere große Mediendateien – ausgeliefert werden. Ein CDN stellt skalierende Speicher- und Auslieferungskapazitäten zur Verfügung und gewährleistet auch bei großen Lastspitzen einen optimalen Datendurchsatz.
CDN-Knoten sind auf viele Orte verteilt und oft auch auf viele Backbones. Sie arbeiten zusammen, um Anfragen (Requests) von End-Nutzern nach Inhalten (Content) möglichst ökonomisch zu bedienen. Einzelne Standorte werden als PoP (Point of Presence) bezeichnet und bestehen aus Server-Clustern.
