    • The invention involves a method for aggregating data in a distributed system. The method includes specifying an aggregation scope including a plurality of nodes, where the plurality of nodes includes a destination node and a plurality of non-destination nodes. The method also includes defining an aggregation tree for the plurality of nodes using at least one Distributed Hash Table, where the destination node is the root of the aggregation tree and where each of the plurality of non-destination nodes is one selected from a group of an interior node and a leaf node in the aggregation tree. The method also includes determining a final aggregation result for the aggregation tree using an aggregation function and aggregation data stored on the destination node and the plurality of non-destination nodes.
    • 本发明涉及一种用于在分布式系统中聚合数据的方法。 该方法包括指定包括多个节点的聚合范围,其中多个节点包括目的地节点和多个非目的地节点。 该方法还包括使用至少一个分散哈希表来定义多个节点的聚合树,其中目的地节点是聚合树的根,并且多个非目的地节点中的每一个是从一组 聚合树中的内部节点和叶节点。 该方法还包括使用聚合功能和存储在目的地节点和多个非目的地节点上的聚合数据来确定聚合树的最终聚合结果。
