目前，P 2 P分布式模式中有非结构化和结构化两种基本拓扑类型。

At present, the P2P distributed model has two basic types: unstructured and structured topology.

结构化P2P网络中主要采用分布式哈希（DHT）搜索算法，它查找速度快、效率高，但受网络拓扑结构的限制其应用有限；

DHT (Distributed Hash Table) search algorithms is mainly adopted in the structured P2P network, it works fast and efficiently, but it is also limited by the network topology structure;

如果索引服务器出现故障，系统会自动转换成全分布式非结构化拓扑结构，大大提高了系统的可靠性。

If the index server fails, the system will automatically convert to the fully distributed unstructured topology. This greatly enhanced the reliability of the system.
