摘　　要：提出了一种结构化P2P覆盖网——LAOverlay,采用组的思想,通过构建两层Hash结构,将本地的资源尽量映射到与本地节点在物理距离上相差较近的节点上,并通过数据本地化较好地解决了资源定位方法与实际的物理结构联系较小的问题,实现了稳定、可靠、查询广泛的资源定位。A kind of the structured P2P overlay network named LAOveday was proposed. The thought of the group was adopted and two-layer Hash architecture was constructed to make the resource of the underlying network node be mapped in a nearby node. The problem that resources location methods had little relationship with real physics structure was resolved, and steady, reliable and inquiring extensive resources location was achieved.
