| 摘 要： | 从P2P网络节点的异构性出发，考虑了节点物理位置，提出了一种分层的混合路由查询协议。该协议利用时间戳在局部实现了节点逻辑位置和物理位置的统一，并引入超级节点解决了节点负载失衡和性能瓶颈的问题。在仿真平台P2PSim上的性能测试表明，该协议在大规模P2P网络中优于Kademlia、Chord、Tapestry。

| Abstract: | Considering the heterogeneity and physical location of nodes, this paper represents a layered mixed query routing protocol. It uses time-stamp to achieve the agreement of physical location and logical position, and introduces super-node to cope with load imbalance between nodes and performance bottlenecks. Simulation test on P2PSim shows that this solution is superior to other protocols, such as Kademlia, Chord, and Tapestry, on large-scale peer-to-peer (P2P) networks. |
