Abstract
As shown in recent studies, video streaming is by far the biggest category of backbone Internet traffic in the US. As a measure to reduce the cost of highly over-provisioned physical infrastructures while remaining the quality of video services, many streaming service providers started to use cloud services, where physical resources can be dynamically allocated based on current demand. In this dissertation, we seek to evaluate and improve the performance for both Adaptive Bitrate (ABR) video streaming and cloud applications. First, we present a set of measurement studies for ABR streaming applications. Using the data from the application, network, and physical layers in different network environments, we identify the key factors that can impact the quality of video delivering services. Then we develop and evaluate a set of new ABR streaming quality adaptation algorithms to improve the user playback experience. In addition, we explore the options for better energy efficiency of ABR video transcoding services and parallel cloud applications. We define a set of energy management policies to enable the utilization of renewable energy sources. We show that, for both applications, by effectively utilizing the renewable energy, our policies can significantly reduce the grid energy usage and corresponding energy cost, while ensuring a satisfying application performance.
