CACHE-AWARE CONTENT-BASED RATE ADAPTATION MECHANISM FOR ADAPTIVE VIDEO STREAMING

摘要

An apparatus is configured to perform a method for adaptive video streaming. The method includes determining a link quality or throughput in at least one of: a first link from a server to an intermediate node or a second link from the intermediate node to a client device. The method also includes, based on the determined link quality or throughput, estimating a link quality in a future time period for at least one of: the first link or the second link. The method further includes determining a schedule for downloading video segments from the server to a cache associated with the intermediate node, the schedule determined based on the estimated link quality in the future time period. In addition, the method includes downloading video segments according to the schedule from the server to the cache during the future time period.
