摘要： The disclosure relates to at least two processor cores of a multicore processor for dual-lane computing of a security-critical application. The two processor cores are used to full capacity in different working cycles for computing operations of different applications, rather than computing operations being redundantly carried out by both processor cores in each computing cycle. This advantageously avoids duplication of the computational capacity required. For the processor cores to monitor each other, the computing operations are alternatingly carried out by the two processor cores. Any errors may be avoided by the error detection mechanisms described. Although the quality of the error detection is somewhat lower than the “dual-lane operation” known from the prior art with parallel, redundant multi-lane calculations, the quality of the error detection may satisfy the requirement of lower computational outlay, (e.g., when an economic implementation of the control system is required). The disclosure therefore combines the requirements of a sufficiently secure error detection with an economic distribution of the computational capacity.

摘要： A method for operating a communications network, in particular an Ethernet network is provided. Network devices that are coupled to the network have a switch device and a control device that is coupled to the switch device, and the switch device has at least one receiving port and a sending port for sending and receiving data via the communications network. Fuse devices for monitoring a particular data transfer rate are assigned to the receiving ports. The fuse devices block data reception at a particular receiving port when a previously determined maximum data transfer rate is exceeded. A possible annular structure using bidirectional communication paths and the limitation of the data transfer rate at the receiving ports improve fail-safety and error analysis in the event of transfer and hardware errors, in particular babbling idiot errors. The invention further relates to a network arrangement having a plurality of corresponding network devices which function according to said method.

摘要： A communications network with a plurality of network devices is provided. The communications network has a plurality N of virtual networks, which are implemented in the communications network in such a manner that each of the network devices is coupled to the communications network via at least two virtual networks. The communications network also has a plurality of network segments. A subset of the network devices is assigned to each of the network segments, wherein each network device arranged at a peripheral region of a network segment has N limiting units, each of the N limiting units being assigned to a respective one of the N virtual networks and designed to limit a data reception of the respective virtual network to a threshold for the data transmission rate predetermined for the respective virtual network.

摘要： In order to reduce data traffic in a network, a master node sends master data to at least one checking instance. The master data are checked by the checking instance. In the absence of errors, either the master data or slave data determined by the slave node are sent by the checking instance to the data-processing unit. When an error is recognized, all master data and slave data available at the checking instance are sent by the checking instance to the data-processing unit.

摘要： A method for operating a communication network, in particular an ethernet network is provided. Each network device coupled to the network has a first control device, a first switch device which is assigned to the first control device, a second control device, and a second switch device which is assigned to the second control device. Each switch device has a transmitting and receiving port for transmitting and receiving data via the communication network, a first internal transmitting and receiving port for transmitting and receiving data between the switch devices, and a second internal transmitting and receiving port for transmitting and receiving data to or from the control device. A respective data exchange at the first and second internal transmitting and receiving port is prioritized over a data exchange at the transmitting and receiving port for transmitting and receiving data via the communication network.
