摘要： 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.

摘要： The invention describes a transmission device having a (TCP/IP) protocol stack (S, S′), which is designed for the transmission of data (D) in a time-sensitive network (TSN). The transmission device comprises at least one TSN-compliant virtual Ethernet interface (2.2, 2.2′) and an associated TSN control unit (3.1, 3.1′). The at least one TSN-compliant virtual Ethernet interface (2.2, 2.2) is designed to send and/or receive a TSN-compliant data stream (2.1, 2.1) in a physical layer (1) of the TCP/IP protocol stack (S, S). The TSN-compliant data stream (2.1, 2.1′) can be configured and/or parameterised by means of the associated TSN control unit (3.1, 3.1′).

摘要： A control method, device, computer program, computer-readable medium and method for data communication in an industrial network that includes at least one node point, via a stream, in which resources are reserved on the at least one node point for data transmission between subscribers via the node point, using a reservation protocol, and data is transmitted via the stream, and a data frame is sent from the transmitter to transmit data from a transmitter to receivers, the data frame being formed from a plurality of data subrecords determined for different receivers, and on at least one output port of at least one node point, at least one data subrecord is filtered out of the data frame, and/or data is transmitted from a plurality of transmitters to a receiver via data frames that have a plurality of data subrecords originating from different emitters, on at least one node point.

摘要： A method is provided which enables industrial communication via the TSN protocol by means of sockets. Owing to the described method, the possibility of communicating with the socket programming known to the programmer via TSN streams is provided. As a result, simple use of the new TSN quality for simple Internet (IP) programming is possible. Existing applications can easily be expanded for TSN and can therefore benefit from the robustness of TSN in a simple manner. In addition, parallel operation is possible; the same mechanism is always used.

摘要： 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.

摘要： 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).

摘要： 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.
