Neotel’s Content Delivery Network What is a Content Delivery Network? Developed to cache (mirror) files across the Internet Concept pioneered by Akamai in the late 1990s CDNs today carry more varied traffic, including streaming Akamai, Limelight, Level 3, Panther, BitGravity dominate Today account for 10% of all Internet traffic, with one third video Video is about a third of the traffic, but not of the economic value Why use a Content Delivery Network? Distributed servers, distributed bandwidth Consistent local performance, close to users Optimised for content e.g. video delivery Only the largest players can build their own Sources: Frost & Sullivan, ATLAS Internet Observatory
