Abstract
Traffic profiling in real time within a video streaming session is described. Multiple data packet flows at a lower layer of the OSI model are observed. A data packet flow pattern is obtained for each observed flow, and each obtained pattern is compared to a pre-defined characteristic streaming pattern. From the observed flows, any data packet flow that has its data packet flow pattern close to the pre-defined characteristic streaming pattern is selected as a video streaming flow. A buffer state of the video streaming flow is identified amongst a filling state, a steady state, and a depletion state, by observing a slope of accumulated data over time. Eventually, multimedia-related information of the selected video streaming flow is provided based on its data packet flow pattern.
