摘要： A method for verifying operation of a first component in a single fault tolerant system is provided. The method includes monitoring for an expected action of the system that indirectly identifies the operating condition of the first component to a second component of the system, when the monitored expected action indicates a faulty operating condition, isolating the first component's errant behavior, and when the monitored expected action indicates a proper operating condition, proceeding with normal operation of the system.

摘要： Methods and apparatus are provided for evaluating the performance of a Time Triggered Ethernet (TTE) system employing Time Triggered (TT) communication. A real TTE system under test (SUT) having real input elements communicating using TT messages with output elements via one or more first TTE switches during a first time interval schedule established for the SUT. A simulation system is also provided having input simulators that communicate using TT messages via one or more second TTE switches with the same output elements during a second time interval schedule established for the simulation system. The first and second time interval schedules are off-set slightly so that messages from the input simulators, when present, arrive at the output elements prior to messages from the analogous real inputs, thereby having priority over messages from the real inputs and causing the system to operate based on the simulated inputs when present.

摘要： A system comprises a plurality of nodes, at least one of the plurality of nodes configured to insert, on a per-virtual link basis, a delay value into a dynamic delay field of a frame corresponding to the respective virtual link, wherein the dynamic delay value represents latency of frames of the respective virtual link. The system also comprises a switch having a plurality of ports, each port coupled to one of the plurality of nodes. The switch is configured to route frames received from the plurality of nodes to one or more of the plurality of nodes. At least one of the plurality of nodes is configured to store frames received from the switch in a buffer and to update the value in the dynamic delay field to reflect the end-to-end system delay.

摘要： Methods and systems for a scalable self-checking processing platform are described herein. According to one embodiment, during an execution frame, a first processing element executes both a high-criticality application and a first low-criticality application. During that same execution frame, a second processing element executes both the high-criticality application and a second low-criticality application. The high-criticality application output from the first processing element is compared with that from the second processing element before the next execution frame, and a fault occurs when the output does not match. The low-criticality application is not duplicated or compared. This and other embodiments allow high-criticality applications to be appropriated checked while avoiding the over-dedication of resources to low-criticality applications that do not warrant self-checking.

摘要： A method for start-up of a network, including a number of nodes, which are connected via channels. The nodes exchange information in the form of messages via the channels. The transition phase of a synchronizing node from its initial phase to a synchronized phase is separated in a first integration phase and a second subsequent cold-start phase. A synchronizing node in the integration phase listens to messages being sent from nodes in the synchronized phase and only reacts to an integration message (i-frame) if the integration message is a valid message. Furthermore, a synchronizing node, wherein integration of the synchronizing node to a set of already synchronized nodes was not successful after a specifiable period, changes into the cold-start phase, in which a cold-start procedure of the node is extracted, wherein in the cold-start phase the node does not react to integration messages of a node in the synchronized phase.
