Internet Path Selection on Video QoE Analysis and Improvements
Abstract— Systematically study a large number of Internet paths between popular video destinations and clients to create an empirical understanding of the location, existence, and repetition of failures. Finding ways to lower a providers costs for real-time, Internet protocol television services through a Internet protocol television architecture and through intelligent destination-shifting of selected services investigate ways to recover from Quality of Experience degradation. Using Live Television and Video on Demand as examples, we can take advantage of the different deadlines associated with each service to effectively obtain these services. Designing and implementing a prototype packet forwarding module called source initiated frame restoration. We implemented source initiated frame restoration on nodes and compared the performance of source initiated frame restoration to the default Internet routing. We found that source initiated frame restoration outperforms IP path selection by providing higher on-screen perceptual quality. These failures are mapped to the desired video quality in need by reconstructing video clips and by conducting user surveys. We can then examine ways to recover from Quality of Experience degradation by choosing one hop detour paths that preserve application specific policies. Path ranking methodology is used to find the path which contain high quality videos with low cost and occupies very low memory space. By ranking videos according to their quality, size, and cost, the top ranking videos can be retrieved by the client.
