Abstract
This invention is related to content delivery systems and methods. In one aspect of the invention, a content provider controls a replacement process operating at an edge server. The edge server services content providers and has a data store for storing content associated with respective ones of the content providers. A content provider sets a replacement policy at the edge server that controls the movement of content associated with the content provider, into and out of the data store. In another aspect of the invention, a content delivery system includes a content server storing content files, an edge server having cache memory for storing content files, and a replacement policy module for managing content stored within the cache memory. The replacement policy module can store portions of the content files at the content server within the cache memory, as a function of a replacement policy set by a content owner.
