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
