Content delivery network
First Claim
1. A method of providing content to end users from a content delivery network, the method comprising:
- storing inventory information in an inventory of each of a plurality of inventory servers in a content delivery network, the inventory information describing which delivery servers within the content delivery network hosts a media file;
providing a uniform resource indicator (URI) corresponding to the media file, the URI configured to identify multiple ones of the inventory servers;
receiving, at a first one of the inventory servers, a request for the media file from a user system, the request specifying the URI and configured to access the first inventory server via anycast routing;
in response to receiving the request for the media file, accessing the inventory of the first inventory server to identify a selected one of the delivery servers within the content delivery network that hosts the media file, based at least in part on geographic proximity of the selected delivery server to the user system; and
redirecting the request for the media file from the first inventory server to the selected delivery server within the content delivery network, thereby enabling the user system to access the media file from the selected delivery server within the content delivery network.

Abstract
A content delivery system for providing content from a content delivery network to end users may include a plurality of delivery servers that host one or more content items and an inventory server having an inventory of content. The inventory of content can indicate which of the delivery servers host the content items. The inventory server may receive a request for a content item from an end user system and may access the inventory of content to determine one or more delivery servers that host the content item. In response to this determination, the inventory server may redirect the request for the content item to a selected one of the delivery servers. The selected delivery server can then serve the content item to the end user system.

8. A method of accessing content from a content delivery network, the method comprising:
-
receiving a uniform resource indicator (URI) corresponding to a media file at a user system comprising computer hardware; submitting a request for delivery of the media file from the user system, the request being submitted to the URI, the URI configured to identify a plurality of inventory servers in a content delivery network; receiving a response at the user system from a first one of the inventory servers selected via anycast routing, the first inventory server comprising an inventory describing which delivery servers i within the content delivery network host the media file; receiving a redirected connection at the user system from the first inventory server to a selected one of the delivery servers that hosts the media file and that has closer geographic proximity to the user system than another of the delivery servers within the content delivery network; and receiving the media file at the user system from the selected delivery server. - View Dependent Claims (9, 10, 11)

12. A system for providing content to end users from a content delivery network, the system comprising:
-
a plurality of edge nodes in a content delivery network, at least some of the edge nodes hosting a media item; a content origin server in the content delivery network, the content origin server configured to provide a uniform resource indicator (URI) corresponding to the media item, the URI configured to identify multiple ones of a plurality of inventory servers in the content delivery network; and means for distributing inventory decisions amongst the plurality of inventory servers in the content delivery network, whereby each of the inventory servers is configured to obtain an inventory specifying locations of the media item in the edge nodes within the content delivery network, wherein each of the inventory servers are configured to; process requests received from end user systems for access to the media item, the requests each specifying the URI for the media item, and enable the end user systems to connect to a selected one of the edge nodes within the content delivery network based on the inventory stored with the inventory server and based at least in part on geographic proximity of the selected one of the edge nodes to the end user systems, thereby enabling the end user systems to access the media item from the selected edge node within the content delivery network. - View Dependent Claims (13, 14, 15, 16, 17, 18)
