    • A system is provided in which autonomous agents manage the distribution of data and index information among the nodes of a computer network. The system comprises a network of computer nodes, each of which includes a data store and an agent interface for execution of the autonomous agents. The autonomous agents move independently among the network nodes, using the agent interface at each node they visit to execute their functions. Various types of agents are employed to implement different functions in the system. Index agents transfer index fields to and from the data stores of the network nodes according to a transfer criterion that is biased to aggregate index blocks into index files on one or more network nodes. Replication agents replicate index files on different nodes to make the system robust against node loss. Balance agents break large index files into smaller subfiles, to prevent overloading any nodes of the network, and query agents locate and retrieve index file entries that match a query criterion. The different agent types manage index and data information on the network nodes without need for a central organizing computer.
    • 提供了一种系统,其中自主代理管理计算机网络的节点之间的数据和索引信息的分发。 该系统包括计算机节点网络,每个计算机节点包括用于执行自主代理的数据存储和代理接口。 自主代理在网络节点之间独立移动,使用代理接口在其访问的每个节点执行其功能。 采用各种类型的代理来实现系统中的不同功能。 索引代理根据偏移到将索引块聚合到一个或多个网络节点上的索引文件的传输标准,将索引字段传送到网络节点的数据存储区和从数据存储区传送索引字段。 复制代理在不同节点上复制索引文件,使系统对节点丢失具有鲁棒性。 余额代理将大型索引文件分解成更小的子文件,以防止网络中的任何节点过载,并且查询代理查找和检索符合查询条件的索引文件条目。 不同的代理类型管理网络节点上的索引和数据信息,而不需要中央组织计算机。
