1. Network system comprising at least one central unit ZE, at least one service unit SE physically connected with ZE and an arbitrary number of physically with ZE connected peripheral units PE1 . . . n, wherein ZE executes at least one thread—

  • called central process or thread—

    , SE executes at least one thread S called critical service—

    , the peripheral or central units execute an arbitrary number of peripheral threads and wherein at least one critical service can build-up or accept at least one standing logical bidirectional communication connection to or from at least one central process, and wherein on top of said connection(s) between the critical service(s) and the central process(es) no further connections can be build-up or accepted by threads running on SE, and wherein direct logical communication connections between peripheral threads running on a peripheral or a central unit and ZE can be established, such that data stored on SE is accessible for the central processes only via a critical service and for the peripheral processes only via a central process and a critical service.
