摘要: Over the last decade, Quality of Experience (QoE) has become guiding paradigm for enabling a more user-centric understanding quality communication networks and services. The intensifying competition among ISPs exponentially increasing traffic volumes caused by online video platforms like YouTube is forcing service providers to integrate QoE into their corporate DNA. This paper investigates problem monitoring from an access provider's perspective. To this end, we present three novel methods in-network measurement impairment that dominates user perception in context HTTP video-streaming: stalling playback. Our evaluation results show it possible detect application-level events at high accuracy using network-level passive probing only. However, only most complex accurate approach can be used prediction due non-linear ties inherent human perception.
