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。
This paper introduces the concept of "partition node" to describe the topologically-critical nodes, whose failure may potentially lead to overlay partitioning.
对等网络的拓扑失配会引起不必要的网络流量，不仅加重了物理网络的负担，而且加大了节点间资源搜索的平均时延。
So both the overhead of the physical network and the average time delay for information searching between peers are aggravated.
保持对等网络与底层网络的拓扑良好契合是保障对等网络性能的重要条件。
It is desirable to make the topology of P2P networks match that of underlying network.
仿真实验显示，SHT模型能有效减少对等网络系统的拓扑维护开销，提高系统稳定性和数据可用性。
The simulation experiments show that SHT model can efficiently reduce the maintenance overheads, and effectively improve the system stability and data availability in P2P systems.
