Abstract

See full text

A method, system and/or computer program product secures response data sent from a responder to a querier. Path information for query data is collected. The path information identifies paths from the querier to the responder and includes a physical machine identifier for each node hosted by a physical machine. One or more sets of return paths are identified for sending response data. For each set of return paths, any return paths that utilize any nodes sharing a physical machine identifier with any node present in another of the return paths within the set of return paths are discarded. The response data is split into a plurality of portions, and each of the plurality of portions is sent from the responder to the querier using a different return path selected from one of the set of return paths.
