A content delivery method and system based on popularity-driven pre- provisioning of content in a content delivery network, CDN (102, 202). In one method, a network element (118, 212, 400) may obtain (502 A) trend data, relative to a particular content to be distributed by the CDN. The network element may also obtain (502B) demographic data of subscribers serviced by the CDN. An expected popularity distribution of the particular content is forecasted (504) based on a metric derived from, at least one of the trend data and the demographic data. A push policy for pushing and/or pre-provisioning of the content to one or more nodes of the CDN is effectuated (506) at the network element based on the expected popularity distribution of the content relative to the geographical region serviced by the CDN. |
