Abstract
A scalable merge technique for information retrieval across a distributed network is provided, as well as a fault tolerant technique for communicating information across the distributed network. The merge technique includes multicasting a query request across a spanning tree of the distributed network from a root node to multiple clients of the tree, and receiving back at the root node, a merged response produced from responses from at least some of the clients of the spanning tree. The fault tolerant technique for communicating information across the distributed network includes assigning a unique identifier to each query request, automatically reconfiguring the network upon detection of a failure of a node of the network, and retransmitting the query request and/or any responses thereto within the reconfigured network.
