System and method for pre-provisioning adaptive bit rate (ABR) assets in a content delivery network

摘要

A system and method for pre-provisioning ABR assets in a content delivery network (CDN). In an example, historical delivery patterns of one or more ABR assets downloaded at respective content delivery nodes of the CDN are monitored. For each content delivery node, one or more delivery rules may be determined based on statistical distributions of the ABR assets delivered over a period of time. When a particular content is determined to become popular at a specific content delivery node, a pre-provisioning policy may be modulated such that only certain representations or adaptation sets of the particular content's assets that pass the delivery rules are pre-provisioned for the specific content delivery node.
