Abstract

The increasing amount of online video content offered by network operators to mobile users opens the door to new challenging optimizations. In a mobile network video applications can be served through several video delivery paths, resulting in different video quality experienced by the end user. The mobile operator is in charge of guiding the video services to keep a target video quality and to optimize the network resource usage, taking into account network metrics related to both core and wireless access networks. We design a framework which runs online algorithms to select the best path for video delivery based on a set of performance metrics evaluated for a range of settings by means of simulation.
