Title:
METHOD AND APPARATUS FOR DATA CACHING IN A COMMUNICATIONS NETWORK
Document Type and Number:
WIPO Patent Application WO/2017/101759
Kind Code:
A1
Abstract:
Methods and apparatus for managing data content among in-network caches of a communication network are provided. In some embodiments, multiple registers are maintained for indexing cached data content. Different data content is indexed in different registers based on parameters such as popularity or content freshness. Customized popularity estimators can be applied to each register, and data content may be indexed by different registers as parameters change. Less popular content can be removed from caches as required. In some embodiments, caches can be grouped into clusters, and deletion of data content from a cache may be modified or inhibited if the cluster still requires a copy of that data content. Data content can be moved between caches of a cluster based on popularity.
