摘　　要：基于结构化的P2P系统在构建覆盖网络时未考虑到与实际物理网络层的结合,导致逻辑拓扑结构与物理拓扑结构严重不匹配问题,提出一种协议无关的拓扑匹配算法,通过事件触发的方式触发网络调整逻辑层的网络拓扑结构。模拟实验表明,本算法在一定程度上提高了网络的拓扑匹配度,降低了网络开销。Based on peer-to-peer system, it is independent of the combined of the underlying physical network when built upon an overlay, which would cause a serious topology mismatching between the P2P logical overlay network and the physical underlying network. About the question, this paper proposed a protocol-independent topology matching method,through the way of event-trigger to trigger the overlay to adjust its structure of the network topology. Simulated experiment indicates this algorithm makes the overlay network match the physical network to some extend, and reduce the cost of overhead of the network.
