【摘要】 针对Chord协议中物理和逻辑网络拓扑不匹配造成查询效率降低的问题,本文提出了一种改进的对等网络协议。该协议综合考虑了物理和逻辑网络拓扑之间的关系,构造了基于“相似属性”的层次性P2P网络。实验结果表明,该协议不仅能够提高查询的效率,而且可以减轻物理网络的负载。更多还原

【Abstract】 Aiming at the problem of mismatch between the physical and logical network topologies in the Chord protocol which causes low efficiency of search,this paper proposes an improved P2P network protocol.This protocol takes the relationships between the physical and logical network topologies into account and constructs a hierarchical P2P network based on homogeneity.The experimental results show that the protocol can not only increase the efficiency of searching更多还原
