A control method, device, computer program and a computer-readable medium and method for data communication in an industrial network, wherein a stream is created between at least two stream subscribers, where resources are reserved on at least one node point, particularly bridges and/or switches between the at least two stream subscribers, and subsequently data is transmitted between the at least two stream subscribers, via the stream, and at least one subscriber of the stream interrupts the emittance and/or reception of data via the stream and resources that are reserved on at least one node point for the at least one subscriber of the stream are released for use for a data transmission that is lower priority than the data transmission via the stream, and where the reservation of the resources being maintained for the at least one subscriber.

Method for data communication in an industrial network, control method, device, computer program and computer-readable medium

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.

Communication device and method for data transmission within an industrial communication network

A network node, computer program, computer-readable medium and method for fail-safe data transmission in a network, in which data packets are transmitted from a sender to a receiver via redundant paths, upon which resources for the transmission are reserved at participating network nodes utilizing an identifier associated with the relevant path, wherein, if a new path is to be found for at least one of the paths involved, then the previous reservations on all redundant paths are maintained, a new redundant path is determined for the at least one path involved and an attempt is made to reserve resources for the transmission on this new redundant path at the participating network nodes, wherein a new identifier associated with the new path is utilized, and if the new reservations on the at least one new path are successful, then previous reservations on the at least one previous path involved are removed.

Network node, computer program, computer-readable medium and method for fail-safe data transmission

The present disclosure concerns a method of synchronization of data packet transmission (P, P, P) in a network (N), including and/or initiating the acts of: Receiving (S), e.g. from a terminal device (T, T, T) of the network (N), one or more data packets (P, P, P) 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 (S) the data packet (P, P, P) in a subsequent transmission window (RT, BE), preferably directly after the transmission window in which the data packet (P, P, P) was received, within the threshold time interval (tt) of the transmission window (RT, BE).

Method of synchronization of data packet transmission

Simulation system and method for simulating processing of reservation enquiries for multicast data streams in communications networks, wherein communication devices which are to be simulated with regard to their behaviour are functionally divided into a communication control plane designated as a control plane and into a data transmission plane designated as a data plane, where simulation system components formed by software containers which are executable in a sequence control environment are case provided for functions of the communication devices associated with the control plane, network infrastructure devices are modelled on the data plane by resources provided via each of the network infrastructure devices, and where the software containers associated with the communication devices are selectively executed in the sequence control environment and coupled together there according to a predetermined topology.

Simulation system and method for simulating processing of reservation enquiries for multicast data streams in communications networks

Methods and systems are provided for improved data packet transmission in a network bridge. Separate data packets received from a plurality of automation components are aggregated into a single data packet stream. The data packet stream is transmitted to another network node, for example, another network bridge.
