Aspects of the subject disclosure may include, for example, a server performing operations including receiving a list of media content items; the media content items have a priority order according to a number of communication devices of network subscribers in a region predicted to request the respective media content items and a predicted location of the communication devices. The operations also include monitoring network traffic to predict a period of decreased network load, and scheduling copying of the media content items from a content server to a caching proxy located in the region; the copying is scheduled to be performed during the predicted period of decreased network load and in accordance with the priority order. The operations further include receiving from the caching proxy a report including the media content items stored at the caching proxy and an amount of storage remaining at the caching proxy. Other embodiments are disclosed.
