US 10057322

US Patent 10057322, titled "Network address resolution," was issued to Sandpiper Cdn LLC. The inventors are Christopher Newton and William R. Power. The patent was filed on December 31, 2015, and issued on August 21, 2018.

Abstract:
The patent describes a content delivery method and related apparatus. It involves an origin system receiving a request for a content resource that includes an embedded resource with a tag. Upon identifying this tag, the origin system uses at least one delivery parameter to obtain a modified embedded resource from a content delivery network (CDN) that is separate from the origin system. The origin system then delivers the content resource to the client device with this modified embedded resource. The modified embedded resource contains a direct link to a node within the content delivery network capable of delivering the content associated with the original embedded resource.

Independent Claims Overview:

• Claim 1 (Content Delivery Method): This claim describes a method where an origin system receives a client's request for a content resource. This resource contains an embedded item with a special "tag." When the origin system sees this tag, it uses certain delivery criteria to get a new, modified embedded item from a separate Content Delivery Network (CDN). Finally, the origin system sends the original content resource to the client, but with the modified embedded item, which now includes a direct link to a specific server (node) within the CDN that can deliver the content.

• Claim 11 (Content Delivery Network): This claim describes a Content Delivery Network (CDN) system. It comprises at least one processor with computer-readable instructions to provide an Application Programming Interface (API). Through this API, the CDN receives an embedded resource and associated parameters from a separate origin system. The CDN then generates a modified embedded resource that provides a direct link to a node within the CDN for accessing the content. The CDN delivers this modified embedded resource back to the origin system. Subsequently, the CDN's node receives a request from a client device for the content and provides it to the client.

• Claim 15 (Method - CDN Perspective): This claim is similar to Claim 11 but is phrased as a method performed by the Content Delivery Network. It involves the CDN providing an API, receiving an embedded resource and parameters from a separate origin system via the API, generating a modified embedded resource with a direct link to a CDN node, delivering this modified resource to the origin system, and then the CDN node receiving a request from a client device for the content and providing that content.

Abstract:
The patent describes a content delivery method and related apparatus. It involves an origin system receiving a request from a client device for a content resource that includes at least one embedded resource with a tag. Upon identification of the tag, at least one delivery parameter is used by the origin system to obtain a modified embedded resource from a content delivery network (CDN) that is separate from the origin system. The content resource is then delivered by the origin system to the client device with the modified embedded resource. The modified embedded resource includes a direct link to a node within the content delivery network that can deliver content associated with the embedded resource.

Independent Claims Overview:

• Claim 1 (Content Delivery Method): This claim outlines a method where an origin system receives a request from a client for a content resource. This content resource contains at least one embedded resource that has a specific "tag." When this tag is identified, the origin system uses one or more delivery parameters to get a "modified embedded resource" from a Content Delivery Network (CDN), which is distinct from the origin system. The origin system then sends the original content resource, now containing the modified embedded resource, to the client. The key aspect of this modified embedded resource is that it provides a direct link to a specific server (node) within the CDN from which the client can directly obtain the embedded content.

• Claim 11 (Content Delivery Network Apparatus): This claim describes a Content Delivery Network (CDN) itself, which includes at least one processor and non-transitory computer-readable medium with instructions. These instructions enable the CDN to:

  • Provide an Application Programming Interface (API).
  • Through this API, receive an embedded resource and at least one associated parameter from an origin system (which is separate from the CDN).
  • Generate a modified embedded resource that provides a direct link to a node within the CDN, allowing clients to get the content associated with the embedded resource.
  • Deliver this modified embedded resource back to the origin system.
  • Receive a request for the content from a client device at the specified CDN node.
  • Provide the requested content to the client device.

• Claim 15 (Content Delivery Network Method): This claim defines a method performed by a Content Delivery Network. The steps are:

  • Providing an Application Programming Interface (API) at the CDN.
  • Receiving, at the API, an embedded resource and at least one associated parameter from an origin system (again, separate from the CDN).
  • Generating a modified embedded resource that provides a direct link to a node within the CDN for obtaining the content related to the embedded resource.
  • Delivering this modified embedded resource from the CDN to the origin system.
  • Receiving a request from a client device at the CDN node to obtain the content.
  • Providing the content to the client device.
