摘要: A method and system for delivering content with a content delivery network (CDN) to a user computer is disclosed. After an initial request to a point of presence (POP) of the CDN for the location of the content object, an Anycast Internet protocol (IP) address is assigned. The user computer requests the content object which may find its way to the same or a different POP depending on what is closer in Internet terms. The request returns a POP-specific IP in a redirect such that the request resolves to the POP referenced in the immediately preceding sentence. One or more edge servers deliver the content object to the user computer.

摘要: A method or system for transferring information during the domain name service (DNS) lookup to more effectively utilizing the content delivery network (CDN) is disclosed. Information gathered from DNS request is used to identify information on how to serve the content with a chosen IP address returned from the DNS lookup. The DNS server selects from a number of possible IP addresses after analyzing information from the DNS request and popularity of associated content. The different IP addresses will result in different edge servers providing content. An IP address could be provided for popular content in a way that will tend to populate more content caches from the pool of edge servers in one embodiment.

摘要: A method of providing media at multiple bit rates using partial object caching may include receiving, from a first user device, a first request for a media object encoded at a first bit rate; providing the first portion of the media object to the first user device; and caching, in a partial object cache, the first portion of the media object. The method may additionally include receiving, from a second user device, a subsequent request for the media object encoded at the first bit rate; providing the first portion of the media object as retrieved from the partial object cache; and receiving a request for the media object encoded at a second bit rate. The method may further include modifying the request for the media object encoded at the second bit rate to instead request a second portion of the media object at the second bit rate.
