US Patent 8976790 Disjoint data path routing for integrity and availability augmentation

A method comprises transmitting a plurality of copies of a message from each of a first transmission node and a second transmission node, each copy having a respective identification and forwarding each of the plurality of copies of the message among other nodes in the network based, at least in part, on the respective identification of each copy such that each copy of the message traverses a predetermined communication path among the other nodes. A respective first received copy is compared to a respective second received copy at each of the other nodes. The integrity of the respective first and second copies is validated at each of the other nodes if the copies match and the copies traversed disjoint communication paths.
