= Content-Delivery-Network. CDN is a system that ensures fast provision of accessed websites with particularly high traffic and a high reach. The load distribution of the server is supported and the user experience (UX) is optimized.


A CDN consists not only of a server but of a whole group of servers (network). A so-called node distributes the data to other servers, so the path of the data depends exclusively on the geographical location of the user. The closer the respective server is to the user, the shorter the response time and the faster the content can be delivered.

Range of application

Especially for streaming of audio and video files (moving image) content delivery networks are used.
