摘要： A computer and software method and apparatus for distributed data processing which provides agreement between data sources (sensors) and data sinks (actuators) as to what data has been written into a shared buffer. The invention further provides methods and means for meeting data timeliness requirements. Invention employs a programming primitive which recognizes semantics so as to provide a consistent view of computation modules over prescribed time intervals, called “epochs”. Application-level control of the asynchrony and timing of information flow between various computation modules is realized. The invention has applications which include sensor fusion and network gaming.

摘要： A method and apparatus is disclosed which provides improved security in distributed-environment voting. At least three voting processors running a voting algorithm are connected to a local area network (LAN) and exchange their individually determined results of a process application. Each result is committed to an interface module where it is checked, authenticated and buffered. The allotted time for receiving and buffering committed results is constrained by a first timed interval within the interface module. The first timed interval may be reset several times. The allotted time for checking and comparing the committed results from each processor is constrained by a second timed interval within each voting processor. A majority vote of those authenticated committed results is formed once all necessary iterations of the both the first and second timed intervals are completed. Enhanced security is thereby afforded to the overall voting process and yields a majority vote that is correct despite the introduction of errors associated with faulty or hostile processors.
