摘　　要：负载平衡功能是P2P系统对于传统C/S结构体系的显著特点之一。P2P系统可以利用网络中多个可用资源服务提供实体来为请求者提供服务,从而显著降低单个节点上的负载,达到保证服务质量的目的。在已有的P2P系统的环境中探讨由于使用了导向搜索产生的系统网络负载平衡问题,并介绍了根据底层系统的特点采用的动态标价方案的原因、原理、性能模拟测试和结果。Load balancing is one of the characteristics of P2P system against traditional C/S paradigm. P2P system is able to use multiple available resource providers in the network to provide services for the requesters, so that it tremandously decreases the load of the single node and guarantees the quality of service. The problems brought out by the guided search approach in an existed P2P environment are discused, and the reasons, priniples, performance evaluation and results of the proposed dynamic pricing approach adopted by the system according to the characterisitics of the system infrastructure are analyzed.
