| 摘 要： | 在基于Gnutella协议的Peer-to-Peer网络中，消息生存时间（TTL）机制、唯一标示符（UID）机制和网络异构延迟共同作用形成了短路效应，限制了查询消息的转发范围。提出了一个短路效应的解决方案。通过在拓扑结构中加入环形结构并改进查询消息转发算法，消除了短路效应的影响，提高了Gnutella网络的查询效率。仿真实验证明了该方案的有效性。 |

| Abstract: | In the Peer-to-Peer network based on Gnutella protocol, the combined action of Time-to-Live（TTL）mechanism, Unique Identification mechanism and heterogeneous latency formed the Short- circuiting Effect, which limited the forwarding scope of query message. This paper proposed a solution which added a ring structure to Gnutella topology and modified the query message forwarding algorithm. The solution eliminated short-circuiting effect and increased the query efficiency in Gnutella network and was indicated to be practical and effective in simulations. |
