Abstract
A content distribution network (CDN) comprising a hierarchy of content storage nodes (CSNs) or caches having storage space that is allocated between local space for storing locally popular content objects and federated space for storing a portion of the less popular content objects. Local space and federated space based upon changes in content object popularity and/or other utility factors. Optionally, parent/child (upstream/downstream) communication paths are used to migrate content between CSNs or caches of the same or different hierarchical levels to avoid utilizing higher price top hierarchical level communications channels.
