A Measurement Study on AS-Aware P2P Streaming Strategies

This paper presents a measurement study of AS-aware P2P streaming solution over real-world Internet topology. By using the accesses of nodes of PlanetLab testbed, the authors create a detailed AS-level map including the end-to-end path of all nodes, as well as the relationship of all involved ASes. Based on this map, the authors evaluate AS-aware P2P streaming solutions with different goals, i.e., minimizing AS hops and maximizing AS revenue, as well as the random P2P streaming solution which has no AS-awareness built in. Their findings suggest that AS-awareness can help existing P2P solution to significantly decrease load on Internet, and improve upon the uneven financial distribution among ASs.
