Abstract
The disclosure relates to a method and device for time-controlled data transmission in a TSN. A new traffic shaping method is described for time-sensitive data streams. The objective is to offer the same real-time performance and configuration complexity as in the prior art but without the need for time synchronization throughout the entire network. The traffic shaper provides that a data frame that is received by a bridge in a first-time interval is passed by this bridge to the next hop/bridge in the next time interval. Each bridge knows the start time of the time interval that belongs to a particular data stream. Each data frame must contain a so-called 'delay value,' thus a delay value which is measured by each bridge using a local clock that measures the delay time spent by the data frame in the queue at the outgoing port.
