Abstract:
The invention relates to a method for synchronizing local clocks in a distributed computer network, where said computer network consists of a number of components that are connected to each other via bi-directional communication links, characterized in that a) an a priori configured set of components of the network generates synchronization messages and sends these synchronization messages to the network, and b) an a priori configured set of components consumes the generated synchronization messages, and c) one or more message-relaying components in between a component that generates a synchronization message and the component that consumes the synchronization message will add a delay value to the synchronization message reflecting the delay imposed by the message-relaying component, d) a component that is configured to consume a synchronization message will delay a received synchronization message upon reception for a duration that is calculated by an a priory configured value for the maximum transmission delay (“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 of said component.
