In this talk I will cover the inner workings of a commercial content delivery network for streaming media. I will start by showing how the network is organized and will then show how end users are mapped to network nodes, how load balancing works and how content migrates from an origin node to the network nodes. I will also examine the transport mechanisms that ensure a high quality end-user experience while keeping transmission costs low.
Finally I will cover other issues of operating such a network including collecting usage information, allowing authenticated only access and integrating it with a storage subsystem.
