Abstract: A method is provided to detect and handle failures in the communication in a network, including a sender (201, 203) and a receiver (202, 501, 502, 503), where communication between the sender and the receiver is message-oriented. The method includes: (a) the sender sending a message (M101, M101-C, M102-C) to the receiver; (b) the sender monitoring the transmission process of the message inside the sender and/or monitoring the message; (c) the sender executing a correctness check of (i) the message, e.g., its contents, and/or (ii) the transmission process of the message inside the sender; and (d) after the correctness check(s) has/have been completed, the sender informs the receiver of the result of the correctness check(s), wherein (e) the receiver of the message marks the message as being faulty and/or discards the message if the result of a correctness check indicates that the message and/or transmission process is faulty.

Abstract: In a network based on IEEE 1588, comprising a plurality of nodes (201, 501) and a plurality of connections where each connection connects at least two nodes to allow communication between nodes including the exchange of messages according to a network protocol, the synchronization of IEEE 1588 is improved by allowing multiple grandmaster clocks (701) to operate simultaneously in the system. Thus, the re-election protocol of IEEE 1588 is made obsolete. For this, a multitude of nodes form a subsystem implementing a high-availability grand master clock (301) according to the IEEE 1588 Standard, wherein the subsystem is configured to tolerate the failure of at least one of said nodes forming said subsystem. Bi-directional communication link (401) are configured for physically connecting a IEEE 1588 Master clocks (201) and/or IEEE 1588 Slave clocks (201) to the subsystem implementing a high-availability grand master clock (301).

Abstract: The invention relates to a method for processing real-time data in a distribution unit of a distributed computer system, the computer system comprising a plurality of node computers and distribution units, the distribution unit containing, in addition to a switching engine (SE) and a switching memory (SM), one or more application computers each with one or more application central processing units and each with one or more application memories (AM), wherein the switching engine of the distribution unit, when it receives, at one of its ports, a message intended for an application computer, forwards this message to the addressed application computer through a direct memory access (DMA) unit that is arranged between the switching memory and the application memory of the addressed application computer and that is under the control of the switching engine. The invention also relates to an expanded distribution unit and a computer system with such expanded distribution units.

Abstract: The invention relates to a method for distributing event-triggered (ET) and time-triggered (TT) messages in a distributed real-time system by means of a distributor unit that comprises a low-level relay unit (LLVME) and a high-level relay unit (HLVME), wherein communication ports of the distributor unit to other relay units and/or end systems of the real-time systems are attached to the LLVME. The invention further relates to such a distributor unit and to a real-time system comprising such a distributor unit. According to the invention, the LLVME has access to a global time base and is configured to differentiate between ET messages and TT messages, wherein the LLVME forwards an ET message that is incoming at one of its ports to the HLVME such that the HLVME can carry out the analysis and temporal scheduling of said ET message before it delivers this ET message back to the LLVME for issue at the designated output ports of the LLVME, and, prior to the known issuing of a TT message, the LLVME transmits a pause frame to the HLVME such that no ET message is scheduled to be transmitted by the HLVME during this anticipated and scheduled TT message transmission slot, and wherein the LLVME delivers an incoming TT message directly for issue at the designated output ports in accordance with the known time plan.
