Recent years have witnessed rapid growth of innovative and disruptive Internet services such as video streaming and peer-to-peer applications. As network traffic of these applications continues to grow, it has become a challenging task to understand their communication patterns and traffic behavior of end hosts engaging in these applications. This paper presents a novel approach based on behavioral...
Recently, application-layer overlay networks have been suggested as a promising solution for live video streaming over the Internet. To organize a multicast overlay, a natural structure is a tree, which, however, is known vulnerable to end-hosts dynamics. Data-driven approaches address this problem by employing a mesh structure, which enables data exchanges among multiple neighbors, and thus, greatly...
This paper presents a systematic in-depth study on the existence, importance, and application of stable nodes in peer- to-peer live video streaming. Using traces from a real large-scale system as well as analytical models, we show that, while the number of stable nodes is small throughout a whole session, their longer lifespans make them constitute a significant portion in a per-snapshot view of a...
