摘要： A method for synchronizing local clocks in a distributed computer network, wherein end systems and switches of the network executes the method as a synchronization state machine, which uses three different frame types. The states in the state machine belong to an unsynchronized or to a synchronized set of states. All end systems being configured as Synchronization Master periodically send coldstart frames in one of the unsynchronized states, all end systems being configured as Synchronization Master react to the reception of a coldstart frame by sending a coldstart acknowledgment frame a first timeout after the reception of the coldstart frame on all replicated communication channels. First timeout is reset when a consecutive coldstart frame is received before the coldstart acknowledge is sent, and all Synchronization Masters react to the reception of a coldstart acknowledgment frame by starting a second timeout and enter a synchronized state when the second timeout expires.

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： The goal of the present invention is to improve the useful data efficiency and reliability in the use of commercially available ETHERNET controllers, in a distributed real time computer system, by a number of node computers communicating via one or more communication channels by means of TT ETHERNET messages. To achieve this goal, a distinction is made between the node computer send time (KNSZPKT) and the network send time (NWSZPKT) of a message. The KNSZPKT must wait for the NWSZPKT, so that under all circumstances, the start of the message has arrived in the TT star coupler at the NWSZPKT, interpreted by the clock in the TT star coupler. The TT star coupler is modified, so that a message arriving from a node computer is delayed in an intelligent port of the TT star coupler until the NWSZPKT can send it precisely at the NWSZPKT into the TT network.

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.

摘要： 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).

摘要： A method for synchronizing local clocks in a distributed computer network includes a number of components that are connected to each other via bi-directional communication links. An a priori configured set of components generates synchronization messages and sends these messages to the network. An a priori configured set of components consumes the generated messages. One or more message-relaying components in between a component that generates a synchronization message and the component that consumes the message adds delay value to the message reflecting the delay imposed by the message-relaying component. A component that is configured to consume a synchronization message delays a received synchronization message upon reception for a duration that is calculated by an a priori configured value for the maximum transmission delay minus the value of the sum of all delay values added to the received message before further usage of the message in the synchronization process.
