Centralized bounded domain caching control system for network edge servers

摘要

A network edge cache management system centrally determines cache content storage and replacement policies for a distributed plurality of network edge caches. The management system includes a content selection server that executes a first process over a bounded content domain against a predefined set of domain content identifiers to produce a meta-content description of the bounded content domain, a second process against the meta-content description to define a plurality of content groups representing respective content sub-sets of the bounded content domain, a third process to associate respective sets of predetermined cache management attributes with the plurality of content groups, and a fourth process to generate a plurality of cache control rule bases selectively storing identifications of the plurality of content groups and corresponding associated sets of the predetermined cache management attributes. The cache control rule bases are distributed to the plurality of network edge cache servers.
