Efficient Placement Schemes to Fully Utilize Peer Upstream Bandwidth

Efficiently utilizing limited peer upstream bandwidth is one of key challenges in P2P streaming. Many mechanisms have been proposed to address this issue by considering peer availability, data redundancy, and priority encoding schemes. In this paper, we investigate this issue from a unique aspect: how to place video data at peers with various upstream capacities in order to better utilize their upstream bandwidth. We propose several effective placement solutions. Our analysis and simulation results show the efficacy of the proposed solutions.
