Abstract: Systems and methods for gathering distributed information to improve routing that uses Anycast for assigning deliveries between a number of geographically-distant points of presence (POPs) are disclosed. The POPs share the same Internet protocol (IP) address. According to Anycast resolution, the Internet aids in assigning a content request initially to a POP. Delivery statistics are gathered from deliveries a the number of POPs and possibly other sources. Where it is determined that Anycast found the wrong POP, the content request is reassigned to another POP.

Abstract: 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.

Abstract: A method of distributing partial content objects may include receiving a request for a content object with a content identifier. The method may further include sending the content identifier from an edge server to a distribution server that is configured to determine that the content object is a candidate for partial object distribution, determine a first portion of the content object, and cause the first portion of the content object to be sent to the edge server. The method may additionally include caching, at the edge server, a second portion of the content object, where the first portion of the content object may include the second portion of the content object and a remaining portion of the content object, and where the second portion of the content object is smaller than the first portion of the content object.

Abstract: 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.

Abstract: Systems and methods for gathering distributed information from a number of data agents for a messaging queue, which is coupled to a number of processing subscribers is disclosed. The data agents provide their gathered information to an interface defined by an API. The gathered data may be reformatted or further processed before adding the gathered information to the messaging queue. A number of processing subscribers listen to a content stream produced by the messaging queue to receive data they have subscribed to. Once the processing subscriber receives the content stream, the processing subscriber applies algorithms to the content stream to perform one or more other functions. For instance, the processing subscriber can feed back processed data into the messaging queue and/or perform an action based, at least in part, upon the content stream.

Abstract: 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.

Abstract: 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.

Abstract: Techniques for the distribution of content objects in a content delivery network (CDN) are disclosed. A CDN distribution server detects a content object's availability and determines whether the content object is a candidate for distribution. The distribution server detects the availability of the content object in response to a provider making new or updated content available at a content site or a location within the CDN. The distribution server obtains identifying information for a candidate content object and determines a select portion of the content object to be distributed within the CDN. The select portion can be a predetermined number of bytes located at a predetermined position in the content object, the size and location of which may be determined according to content-specific mapping data. The distribution server pushes the select portion of the content object to one or more groups of CDN edge servers absent an end-user request.

Abstract: 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.

Abstract: 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.

Abstract: Techniques for the distribution of content objects in a content delivery network (CDN) are disclosed. In one embodiment, a CDN distribution server detects the availability of a content object and determines whether the content object is a candidate for distribution.
