<p>A distributed edge network architecture is described in which a data center serves as a primary repository for content uploaded by content providers. From the data center, the content is replicated at all, or a selected group of, geographically dispersed 'intermediate' point of presence ('POP') sites. A plurality of edge POP sites communicate with the intermediate POP sites and serve as network caches, storing content as it is requested by end users. In one embodiment, the edge POP sites are co-located by one or more Internet Service Providers.</p> |
