对等网

The structure of P2P model and routing mechanism of querying message are the key technologies of resource location.

对等网模型结构和查询消息的路由机制是对等网资源定位的关键技术。

Peer-to-peer overlay route model is able to query accurately, but does not sustain semantic query.

现有对等网覆盖路由模型只适应精确查找，存在不支持语义查询的缺点。

After researching on several popular P2P resource locations, a new solution is designed for achieving the goal above.

针对上述目标，在研究了流行的几种对等网资源定位系统之后，给出了解决方案。

This paper introduces the concept of ´partition node´ to describe the topologically-critical nodes, whose failure may potentially lead to overlay partitioning.

提出了分点概念来描述对等网络的拓扑关键点，这些结点的失效很可能导致覆盖网的分割。

Considering the Angle of locating document resources, existing peer-to-peer resource sharing systems only provide coarse-grained resource location based on file names.

从文档资源定位的角度考察，现有的对等网资源共享系统都仅支持基于文件名的粗粒度资源定位。
