Then we analyse the new complex queries method that support large - scale distributed p2p application . finally , we describe an efficient algorithm and data structure that support complex queries based on structured p2p network . coupled with a dynamic load balanceing mechanism , the model can handle both point and range queries regardless of the distribution of the queries 本文首先介绍对等网络系统及其局限性,然后对最近提出的多种支持大规模对等网络的分布式哈希表查找系统进行分析,为了支持复杂查询,在结构化对等网络环境中引入了新的数据结构和算法,使其能支持范围查询和有效的相似查询,再结合动态的负载均衡机制,很好的避免了系统瓶颈。
Positive cluster internet server architecture ( pcisa ) is a fresh new architecture consisting of three parts : dispatcher , server pool and data storage . the servers apply for client requests from the dispatcher in a positive manner , replacing traditional load balance and heart beat mechanisms 主动式集群网络服务器体系结构( pcisa )是一种全新的集群服务器体系结构，由分发器、执行服务器、后端数据存储三部分组成，执行服务器主动向分发器索取用户请求，无须传统的负载均衡机制和心跳机制。
Based on this model , we studies the simultaneous existence of the agent ' s optimal capital stock and income , the government ' s optimal tax and public expenditure ( we call the combination as an equilibrium mechanism ) , this essay draws the equivalent proposition of equilibrium mechanism existing and converts the former problem into another problem of selecting public sector mechanism that only includes the government behavior 在此模型中，我们研究了消费者的最优资本存量和收入，以及政府的最优税收和公共花费的存在性(我们把上述的四元组合称为一个均衡机制) 。本文先建立了均衡机制存在性的一个等价命题，然后将均衡机制存d硕士学位论文n wymunr ’ stimis在性问题转化为只有政府行为的公共部门机制选择问题，从而得到最优税收等的存在性。
