Abstract

Apparatus and methods for managing provision of content to devices in a content delivery network. In one exemplary embodiment, content with a high probability of viewership is sent to consumer premises equipment (CPE) during off-peak periods and stored prior to viewing. An application is utilized to manage decisions related to content provision. The computer program will identify content that is likely to be of interest users associated with respective CPE, and schedule provision of that content in advance of viewing. Then, the system will develop a plan for optimal scheduling of transmission of content to CPEs, often including the use of trickle downloads. The scheduling plan is based collected statistical and historical data on network resource demand to make scheduling decisions. The system allows for the shifting of bandwidth utilization from periods of high demand to those of low demand, and increased performance with regard to user experienced latency.
