A method and system for flexibly processing content objects is disclosed. A content object is stored on one of a plurality of storage devices. A request is received for the content object. Information corresponding to the requested object (e.g., a unique identifier) is transmitted to one or more content directories. A response is received from a first content directory indicating a location of the content object. The content object is requested from the first location, and at least part of the content object is received.

Multicast mapped look-up on content delivery networks

A method for processing content objects with resources associated with a content delivery network (CDN) having a plurality of geographically distributed points of presence (POPs) is disclosed. The resources are enrolled to be accessible from the CDN. Each resource is categorized using tags that categorize the resources. Selection of a policy from a plurality of policies is received, where the plurality of policies define processes to perform on content objects. The selected policy includes an applicability criteria and a call to the resource. Metadata is received at the CDN, the metadata being related to a content object, a requester of the content object and/or a provider of the content object. It is determined that the policy is applicable through analysis of the metadata and/or applicability criteria. The resource is called according to the call in the policy to cause the resource to perform specified processing on the content object.

Policy based processing of content objects in a content delivery network using mutators

A method for populating edge servers within a content delivery network (CDN) having a plurality of points of presence (POPs) is disclosed. A first function is performed that gathers popularity information for a content object. Popularity trends for the popularity information are determined through analysis with historical popularity information. A number of copies of the content object for each of the plurality of POPs is determined. The number is passed as a variable to a second function. The second function is performed that adds or deletes copies of the content object for each of the plurality of POPs as a function of the popularity trend and the number.

Content replication workflow in content delivery networks

A method for processing content objects with a content delivery network (CDN) having a plurality of geographically distributed points of presence is disclosed. Selection of a policy is received from a plurality of policies, where the plurality of policies define processes to perform on content objects stored at the CDN. Each policy includes an applicability criteria and a storage disposition. Metadata is received at the CDN, the metadata characterizing a content object, a requester of the content object and/or a provider of the content object. The content object is received for storage at the CDN. A policy and other policies are determined to be applicable to the content object through analysis of the metadata and/or the applicability criteria. Overlap is resolved between the policy and the other policies found applicable to the content object. The processing of the policy is performed on the content object.

Policy management for content storage in content delivery networks

A method for processing content objects within a content delivery network (CDN) having a plurality of points of presence (POPs) in different defined geographies is disclosed. A content object is gathered from one of the plurality of POPs in a first defined geography. It is determined that a processing function is to be performed on the content object. Geographical restrictions on the processing function are analyzed. A second defined geography for performing the processing function is determined. The content object is sent to a resource that performs the processing function in the second defined geography. The processing function is performed with the resource at the second defined geography to produce a processed content object. From a plurality of content stores in the plurality of POPs, a content store is found to hold the processed content object. The processed content object is stored on the content store.

Content processing between locations workflow in content delivery networks

A method for ingest of content for a content delivery network (CDN) having a plurality of geographically distinct points of presence (POPs). A first landing-pad application program interface (API) is hosted and accessible from a first POP. A second landing-pad API is hosted and accessible from a second POP. First and second content objects are received at the first and second land-pad APIs, respectively. A first tag is analyzed to find it applicable to the first content object. A second tag is analyzed to be applicable to the second content object. First and second storage media are selected based upon the respective analyses of the tags. The content object objects are stored with the respective storage media. The first and second content objects are stored in a consistent file structure.
