Network systems and processes for delivery of electronic content to recipien t processors may be configured to facilitate the delivery of a relatively larg e content items and/or a relatively large number of content items. In one example, a movie rental system and process delivers (downloads) movie files to customers across the Internet (10). System network architecture includes thr ee or more layers of servers, including a main server (12) supporting an interface for recipient processors to request content items, a plurality of parent servers (14), and a plurality of edge servers (16). Edge servers are distributed throughout a region in which the system provides content deliver y services to recipient processors. Parent servers, spaced across the service region, support edge servers. A copy of each content item available through the service is distributed from the main server to each parent server for storage. Parent servers distribute content to edge servers, pursuant to instructions from the main server or requests from the edge servers. The mai n server receives requests for content items from recipient processors and directs recipient processors to edge servers for obtaining requested content items. The main server also authenticates licenses and publishes rules for t he distribution of content items.
