  • Method and apparatus for network fault correction via adaptive fault router
    Patent number: 7434088
    Abstract: A fault router method and system for use in a parallel redundant network environment provide additional safeguards over traditional redundant networks. Where multiple connection faults on multiple machines would ordinarily stifle communications between two or more network entities, the fault router passes packets between redundant networks to bypass connection faults. Compatibility and timing improvements allow for the extension of the parallel network environment, and provide for time-synchronized network operation.
    Type: Grant
    Filed: October 12, 2004
    Date of Patent: October 7, 2008
    Assignee: Invensys Systems, Inc.
    Inventors: Alan Gale, Richard Coombs, Krishan Kumar Dhupar, Alan M. Foskett, Douglas MacDougall
