CDN

Content Delivery Network

Network of servers, distributed at national or international level, for efficient delivery of multimedia contents to the final users. The user, instead of accessing remote web sites to get the required content, accesses a copy of the same content stored on a closer server called “edge node”, with a performance increase and generating a lower amount of traffic on the network backbone. CDNs, whose original purpose was the distribution of web pages, are now also specializing in the OTT distribution of audio/video contents.
