摘要： In at least one embodiment, a method and a system include a node potentially having information responsive to an information request distributed into, for example, a federated coalition network where the node receives at least one information request packet, conducts a search of information at the node to determine if requested information is present, when the requested information is present, then the node sends an acknowledgement to a requesting node, linear network codes the requested information into m packets where m is greater than or equal to k, which is the number of packets needed to be received by the requesting node to reconstruct the requested information, selects multiple paths between the node and the requesting node such that no third party will see more than k−1 different packets, and transmits the m packets distributed over the selected paths. In a further embodiment, the method and system include operation of the network to have the capability to provide responsive information in a protected way.

摘要： Method and system are provided for assessing response routes in a network of connected nodes wherein a querying node propagates a query through multiple routes of intermediate nodes to a data source node and the data source node returns data to the querying node. The method at a data source node may include: receiving a query instance including metadata with route information of the route of intermediate nodes in the network that the query instance has travelled through from a querying node to the data source node; comparing the route information to a route policy; and responding to a query instance which meets the route policy by returning the query response via the route of intermediate nodes of the query instance.

摘要： A query is propagated from a querying node to a destination node in a network of connected nodes, where at least one node is designated as a delay node. A query is transmitted from the querying node to one or more connected nodes in the network of connected nodes. One or more nodes, from the one or more connected nodes, are designated as delay nodes, wherein delay nodes apply delays to the query before retransmitting the query to other nodes from the one or more connected nodes. Upon receiving the query, each node, from the one or more connected nodes, retransmits the query to another one or more nodes from the one or more connected nodes. The query is repeatedly received and retransmitted by the connected nodes until the query is received at the destination node.

摘要： 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.
