Content replacement and refresh policy implementation for a content distribution network
First Claim
1. A non-transitory computer-readable medium storing instructions for managing content in a communication network, the communication network having a core network and an access network with a cache, the access network comprising a base station for communicating with an electronic user device, the medium storing instructions that, when executed by a processor at a location in the access network between the base station and the core network, cause the processor to:
- receive a cache management replacement policy comprising a plurality of content replacement rules, the plurality of content replacement rules each defining a policy specifying when an object in the cache should be replaced;
classify the object into an object group based on an attribute of the object;
determine a first content replacement rule of the plurality of content replacement rules based on the classified object group to apply to the object;
define a trigger condition in the cache management policy specifying when to apply the first content replacement rule, the trigger condition being based on a property of the communication network;
monitor the property of the communication network;
evaluate the monitored property against a threshold amount of available bandwidth or a threshold message latency time;
detect, based on the evaluation, a satisfaction of the trigger condition; and
apply, responsive to the trigger condition being satisfied, the first content replacement rule and replace the object.

Abstract
A method for replacing, refreshing, and managing content in a communication network is provided. The method defines an object policy mechanism that applies media replacement policy rules to defined classes of stored content objects. The object policy mechanism may classify stored content objects into object groups or policy targets. The object policy mechanism may also define metric thresholds and event triggers as policy conditions. The object policy mechanism may further apply replacement policy algorithms or defined policy actions against a class of stored content objects. The media replacement policy rules are enforced at edge content storage repositories in the communication network. A computing device for carrying out the method, and a method for creating, reading, updating, and deleting policy elements and managing policy engine operations, are also provided.
