Problems solved by technology

Despite a low cache hit ratio, all client device requests flow through the proxy cache and unnecessarily increases packet processing overhead in the proxy cache

Embodiment Construction

[0024] A detailed description is given below with reference to the accompanying drawings. The same reference numbers in different drawings may refer to the same or similar elements.

[0025] The systems and / or methods described herein can provide a modular, transparent proxy caching solution that separates cache hits from cache misses, where a cache hit can refer to when a requested resource is stored on a proxy such as a cache server cache, while a cache miss can refer to when the requested resource is not stored in a proxy cache, such as a cache server. The systems and / or methods may enable cache hit traffic to be served by a cache server utilizing an IP address of an origin device storing a resource, and may enable cache miss traffic between a client device (e.g., requesting a resource) and the origin device flow without any layer 7 interception. A cache server may asynchronously retrieve and store resources, such as content, services, etc., using a configured set of IP a...

Abstract

The invention discloses transparent proxy caching of resources. A device that receives a request from a client device for a resource available from an origin device and determines whether the resource is cached in a cache server. When a resource is cached, the device provides a first command instructing the client device to request the resource from the cache server, receives a first new request for the resource from the client device, and enables the client device to retrieve the resource from the cache server based on the first new request. Receive resources. When the resource is not cached, the device creates a firewall filter, provides a second command instructing the client device to request the resource from the origin device, receives a second new request for the resource from the client device via the firewall filter, and based on the second A new request enables a client device to receive resources from an origin device.

Description

Background technique [0001] A service provider is an entity (eg, a business or organization) that sells bandwidth provided by or access to a network (eg, the Internet, data network, telecommunications network, etc.) associated with the service provider. Service providers may include telecommunications companies, data carriers, wireless communication providers, Internet service providers, cable television operators that provide high-speed Internet access, and the like. Rapid growth in content usage such as eg video, audio, images, software downloads creates higher bandwidth demands on service providers, with spikes around significant content and events. [0002] To handle this higher bandwidth demand, service providers deploy server-side transparent Hypertext Transfer Protocol (HTTP) proxy caching devices, such as cache servers, in their networks. Proxy caching devices (also referred to herein as "proxy caches") can cache popular content, which enables service providers to opt...
