This paper presents a measurement study of ASaware P2P streaming solution over real-world Internet topology. By using the accesses of nodes of PlanetLab testbed, we 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, we 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. Our 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. By comparing the performance of ASaware and random P2P solutions, we also point out the necessity to tradeoff between the goals of achieving fairness among peers and optimizing AS-related performance such as intra-AS traffic and financial fairness.
