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.

Enhanced anycast for edge server selection

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.

Partial object distribution in content delivery network

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. Information in various degrees of processing and aggregation can be passed through any number of cycles in a processing ring to allow for a clearinghouse of information to flow in real time or near real time.

Real-time message queuing for a processing ring

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.

Enhanced Anycast for edge server selection

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. The distribution server may detect 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 may push the select portion of the content object to one or more groups of CDN edge servers absent an end-user request.
