Problems solved by technology

In another example, one or more of the components may become overwhelmed with traffic from the network such that one or more end users can no longer connect to the components used to route and deliver requested content
In such cases, the availability of content from the CDN may be temporarily disrupted by the end user's network

Embodiment Construction

[0015] Various aspects of the present disclosure relate to systems, methods, computer program products, etc., for providing failover and load clustering features to one or more proxy servers in a content delivery network (CDN). In an embodiment, the CDN may include a plurality of proxy servers in communication with a router through which requests for content may be received from one or more of the proxy servers. One or more of the proxy servers may advertise a virtual host Internet Protocol (IP) address identifying the proxy server as a device through which particular content in the CDN is available. The virtual IP address may be advertised through a Border Network Protocol (BGP) session with the router. When retrieving content from a storage device, the virtual host IP address may be a specific IP address for the content or a host IP routing address. In order to provide failover features to multiple proxy servers communicating with the router, two or more of the proxy server...

Abstract

Aspects of the present disclosure involve systems, methods, computer program products, and the like, for providing failover and load clustering features to one or more proxy servers of a content delivery network (CDN). In one embodiment, one or more proxy servers may announce a virtual host internet protocol (IP) and, to provide a failover feature, two or more of the proxy servers may also announce a more generic virtual network IP address that includes a broader range of IP addresses associated with the virtual network IP address. In another embodiment, each of the proxy servers in communication with the router may announce a generic IP network address to the router. In response to receiving a request for content from an end user of the CDN, the router may select a proxy server and load balance the received requests among the proxy servers.

Description

[0001] Cross References to Related Applications [0002] This Patent Cooperation Treaty (PCT) patent application claims U.S. Provisional Application No. 61 / 941,576, filed February 19, 2014, entitled "CONTENT DELIVERY NETWORK ARCHITECTURE WITH EDGEPROXY," and the title Priority to US Provisional Application No. 62 / 110,119 for "PROXY SERVER FAILOVER AND LOAD CLUSTERING," both of which are incorporated herein by reference in their entirety. technical field [0003] Embodiments of the invention relate generally to systems and methods for implementing a telecommunications network, and more particularly to systems and methods for providing failover and load clustering features to one or more proxy servers in a content delivery network. Background technique [0004] Content delivery networks (CDNs) are increasingly used to distribute content (eg, video, multimedia, images, audio files, documents, software, and other electronic resources) to end users on behalf of one or more conten...
