Abstract: Method for data transmission within an industrial communication network, wherein selected datagrams are transmitted within predetermined time intervals, which are synchronized at all network nodes, where a number of network nodes from the respective source network node to the respective target network node is determined for forwarding the selected datagrams in each case, and where the selected datagrams are transmitted during first periodic time intervals having a first protection interval length in the event of a determined number of network nodes corresponding to at least one predefined threshold value and, in contrast thereto, if a determined number lies below the threshold value, then the selected datagrams are transmitted during second periodic time intervals having a second protection interval length, which is shorter than the first protection interval length.

Abstract: The present disclosure concerns a method of synchronization of data packet transmission (P1, P2, P3) in a network (N), including and/or initiating the acts of: Receiving (S1), e.g. from a terminal device (T1, T2, T3) of the network (N), one or more data packets (P1, P2, P3) after a threshold time interval (tt) of a periodic transmission window (RT, BE), wherein the threshold time interval (tt) is arranged at the beginning of said periodic transmission window (RT, BE), and Forwarding (S2) the data packet (P1, P2, P3) in a subsequent transmission window (RT, BE), preferably directly after the transmission window in which the data packet (P1, P2, P3) was received, within the threshold time interval (tt) of the transmission window (RT, BE).

Abstract: The invention relates to methods and to a device for the modular orientation of an AVB stream. The introduction of a new attribute (L_BRIDGE) into the reservation protocol that has been further developed for TSN allows to better use the existing mechanisms in the Ethernet Standard. To this end, each receiver and each transmitter has to announce himself in the network (already existing for the transmitters).

Abstract: Sensors of a control system transmit detected cyclical actual states of a technical industrial process to a common central unit via a first protected connection of a first open communication network once within a specified time window. The central unit transmits cyclical control signals commensurate with the actual states to multiple actuators via a second protected connection of a second open communication network once within the specified time window. Each sensor supplies the actual state detected by the sensor to the first open communication network within a respective transmitter-side sub-region within the time window. The central unit receives the transmitted actual states within a respective corresponding receiver-side sub-region within the time window. The transmitter-side sub-regions of the sensors are specified such that the receiver-side sub-regions are disjointed from one another.

Abstract: The invention relates to a method and to a device that describe a real-time network plan for industrial control and monitoring applications, wherein standard Ethernet switching elements are used for the communication network, in particular on the basis of the new mechanisms according to the IEEE 802.1 TSN Task Group. The sequence plan combines clocked data transfer with the stream reservation concept and thus provides determinism with guaranteed maximum latency and access controls at runtime.

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.
