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, 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 AS-aware 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.
