摘要： 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.

摘要： 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.

摘要： 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.
摘要翻译： 公开了用于从用于消息队列的多个数据代理收集分布式信息的系统和方法，其耦合到多个处理订户。 数据代理将其收集的信息提供给由API定义的接口。 在将收集的信息添加到消息队列之前，收集的数据可以被重新格式化或进一步处理。 多个处理订阅者收听消息队列产生的内容流，以接收他们订阅的数据。 一旦处理订户接收到内容流，处理订户就向内容流应用算法来执行一个或多个其他功能。 例如，处理用户可以至少部分地基于内容流来将经处理的数据反馈到消息队列中和/或执行动作。 不同程度的处理和聚合的信息可以通过处理环中的任意数量的循环，以使信息交换所能够实时或接近实时地流动。
