Content delivery network

A system for cross-tabulating content usage information at multiple nodes of a content delivery network architecture, the system comprising:

• a plurality of delivery servers in a content delivery network, each of the delivery servers operative to provide access to content, each of the delivery servers comprising one or more processors operative to:
• determine usage data, the usage data comprising information corresponding to delivery of content from the delivery server, the content being hosted by the delivery servers on behalf of one or more content providers, each of the one or more content providers having an account with an operator of the content delivery network,
• batch at least a portion of the usage data to produce first batched usage data, the first batched usage data comprising a summary of the usage data, and
• provide the first batched usage data to a usage server;
• the usage server operative to receive the first batched usage data from each of the delivery servers, to batch the first batched usage data from each of the delivery servers into second batched usage data, and to provide the second batched usage data to a billing server;
• and
• the billing server operative to cross-tabulate the second batched usage data with usage data stored in a provider database to produce overall usage data.

A system for tracking content deliveries in a content delivery network, the system comprising:

• a plurality of delivery servers in a content delivery network, the delivery servers comprising computer hardware, each of the delivery servers operative to:
• track delivery data corresponding to content deliveries performed by the delivery server,
• cross-tabulate the delivery data to produce condensed delivery data, and
• provide the condensed delivery data to a usage server;
• and
• the usage server operative to cross-tabulate the condensed delivery data received from each of the delivery servers to produce second condensed delivery data.

A method for tracking content delivery information in a content delivery network, the method comprising:

• receiving, with a first usage server comprising one or more processors, first delivery data corresponding to first content deliveries performed by a first delivery server, the first delivery data comprising information about deliveries of content by the first delivery server;
• receiving, with the first usage server, second delivery data corresponding to second content deliveries performed by a second delivery server;
• combining, using the one or more processors of the first usage server, the first and second delivery data received from the first and second delivery servers to produce first summarized delivery data;
• and
• providing the first summarized delivery data to a billing server, the billing server configured to combine the first summarized delivery data with second summarized delivery data received from a second usage server to produce combined delivery data, and to store the combined delivery data in a provider database comprising physical computer storage.
