Adaptive HTTP streaming with centralized consideration of multiple streamshas gained increasing interest. It poses a special challenge that the interestsof both content provider and network operator need to be deliberately balanced.More importantly, the adaptation strategy is required to be flexible enough tobe ported to various systems that work under different network environments,QoE levels, and economic objectives. To address these challenges, we propose aMarkov Decision Process (MDP) based network-assisted adaptation framework,wherein cost of buffering, significant playback variation, bandwidth managementand income of playback are jointly investigated. We then demonstrate itspromising service provisioning and maximal profit for a mobile network in whichfair or differentiated service is required.
