Abstract: In structured P2P network, loading imbalance results in the problem of single failure, network congestion, request delay and even worst problems. This paper proposes an effective loading balance algorithm to prevent hot spots based on the analysis of requested datas and nodes processing difference. Through experiments and simultaed results, the proposed algorithm can effectively improve loading unbalance in structured P2P network.
