Abstract
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.
