摘　　要：本文提出了一种基于站的DHT与洪泛相结合的P2P资源混合定位模型。在继承DHT优越性的基础上,本模型利用底层网络物理邻居拓扑关系,提高了DHT的健壮性和扩展性;同时,引入隐式洪泛树的洪泛定位机制改善了定位的灵活性。本文对这一模型作了介绍,并对性能作了简要分析。在实际应用中的测试及仿真结果表明,该模型能有效地减少定位过程中的通信开销和响应延迟,从而使其可以平滑适应网络规模的扩大。The paper proposes a station-based DOS resource mixed locating model combined with DHT and flooding. This model not only inherits the advantages of DHT locating, but also makes use of the bottom-layer＇s topology neighborhood to improve the robustness and scalability. Meanwhile the model introduces an implicit flooding tree to ameliorate the flexibility of locating. This paper details the mixed locating model and analyzes its performance. The test and simulation results show that this model can effectively reduce the communication cost and response delay. Consequently, it can smoothly adapt to the extension of network.
