Abstract
A content controller monitors current network capacity usage and ongoing streaming data requests. Based on the collected information, the content controller assigns a data segment prefetching task to a data storage (e.g., a cache) of the network. One or several caches can be used to prefetch one or more data segments, depending on the network conditions and the speed with which a data store can retrieve the data over the network. The task assignment is performed for a given period of time, which is defined as a round. Periodically, the controller uses information collected from previous rounds, such as the history of streaming data requests and bandwidth usage, to determine the data segments to be prefetched by data stores in the next round.
