Embodiment Construction

[0015] Aspects of the present disclosure relate to systems, methods, computer program products, etc. In one example, a proxy receives client requests for content to be served by a CDN. Content can range from software patches to digital movies, among many other forms of content. The proxy cache device is a relatively high-speed device compared to the various possible devices that make up one or more edge clusters. Therefore, if the proxy already caches the requested content, it can serve client content requests directly at a faster rate than serving content from an edge cluster. Otherwise, the proxy cache can request content from the edge cluster and store the content for fast retrieval in response to additional requests for content. In one embodiment, the proxy cache may perform an analysis of the request or series of requests to determine whether the content is cached at the proxy cache device.

[0016] Additionally, proxy caches can perform hashing when the proxy does no...

Abstract

Aspects of the present disclosure relate to systems, methods, computer program products, etc. for a CDN architecture utilizing one or more proxy caching devices between a requesting device and an edge cluster of a content delivery network (CDN). The proxy cache device is a relatively high-speed device compared to the various possible devices that make up one or more edge clusters. Therefore, if the proxy already caches the requested content, it can directly serve the client's content request at a faster rate than serving the content from the edge cluster. Otherwise, the proxy cache can request content from the edge cluster and store the content for fast retrieval in response to additional requests for content. In one embodiment, the proxy cache may perform an analysis of the request or series of requests to determine whether the content is cached at the proxy cache device.

Description

[0001] Related Application Cross Reference [0002] This Patent Cooperation Treaty (PCT) patent application claims U.S. Provisional Patent Application No. 61 / 941,576, filed February 19, 2014, entitled "CONTENTDELIVERY NETWORK ARCHITECTURE WITH EDGE PROXY," and filed January 30, 2015, entitled " PROXY SERVER FAILOVER AND LOAD CLUSTERING," U.S. Provisional Patent Application No. 62 / 110,119, which is hereby incorporated by reference in its entirety. technical field [0003] Embodiments of the present invention generally relate to systems and methods for implementing telecommunications networks, and more particularly, to systems and methods for content delivery networks including edge proxy caches for cache pop content and slice the request for the content in the content storage device. Background technique [0004] Content delivery networks (CDNs) are increasingly used to distribute content, such as video, multimedia, images, audio files, documents, software, and other electro...
