Network Monitoring for Video Quality Over IP
Category: Networking and Communications
Overview This paper considers the problem of predicting application-level video quality based on monitoring video packets within the network. The goal is to detect impairments (either server- or network-induced) that will affect the quality of the video displayed to the viewer. The paper presents a framework for in-network video quality degradation monitoring, and describe the information that can be extracted by processing the observed packets at different depths. For the popular Windows Media streaming format, it presents techniques to estimate video quality degradations based on examining information at the IP, TCP and application-layers. It demonstrates the potential of the methods using IP traffic observed at a broadband head-end over a one-week period.
