| Abstract: | : | Internet video is used extensively for entertainment, education, work, and telehealth, making it the largest contributor to Internet traffic. Due to these two factors, i.e., popularity and resource utilization, it is crucial to understand the network dynamics of Internet video. Understanding network behavior of the video, however, has several challenges, including (1). complex interactions among entities on the network path (e.g., CDNs, ISPs) and within the vertical network stack, (2). limited information available to some stakeholders (e.g., network operators), and (3). heterogeneity in network and user contexts. In this talk, I will cover two of my research directions that use network data to provide insights into the dynamic behavior of the Internet video applications. The first is on using passive measurements to enable network operators to understand Quality of Experience metrics for HTTP-based adaptive streaming (e.g., Netflix, YouTube). The second is on using empirical network data to understand performance and network utilization of video conferencing applications (e.g., Zoom). The talk will conclude with a brief discussion of my ongoing work on mapping broadband inequity and future research plans. |
