Various example embodiments for supporting intent-based networking within a communication network are presented herein. Various example embodiments for supporting intent-based networking within a communication network may be configured to support a management system configured to support management of a network based on use of scalability for management of the network. Various example embodiments for supporting intent-based networking within a communication network may be configured to support a management system configured to support management of a network based on use of scalability for management of the network where the scalability is based on use of partitioning of topics in a publisher-subscriber model used for exchange of information between elements of the management system that support management of the network based on intent-based networking.

A control portion (10) of a network equipment (1) attempts, when connected to other equipment, connection by using a predetermined communication parameter through communication portions (11, 12), and in a case that the communication is not established, the control portion (10) executes negotiation and establishes communication with the other equipment by using an agreed communication parameter.

A CANopen-based train network data transmission method includes: switching, when a first CAN channel of a first slave node is detected as faulty, to a second CAN channel of the first slave node to receive over a standby network a heartbeat packet and data transmitted by another relevant node; monitoring, if no heartbeat packet transmitted by a relevant second slave node is received from the standby network within a preset heartbeat period, by an active master node, in an active network, a heartbeat packet and data transmitted by the second slave node; receiving, through the second CAN channel, the heartbeat packet and the data of the second slave node forwarded by the active master node to the standby network when the active master node detects in the active network the heartbeat packet and the data transmitted by the second slave node through the first CAN channel.

The invention relates to a modular conveyor system, comprising multiple individual conveyor modules, wherein an individual conveyor module comprises at least one conveyor device, at least one power supply, at least one actuator for driving the conveyor device, an output unit for the control of the actuator and an integrated control unit, wherein the integrated control unit has a computing unit for processing information and a communications unit, and wherein the communications unit is designed to carry out the communication of the individual conveyor modules with a central control system, on the one hand, and/or the communication of the individual conveyor modules with one another, on the other hand, in such a way that the communication of the individual conveyor modules with one another is implemented at two logical communication levels. The invention further relates to a method for controlling modular conveyor systems.

A route failure and a device failure are detected in a short time without erroneous recognition. A multiplexing system includes: a first system having a pair of processing devices forming a pair; a second system having a pair of processing devices forming a pair that are different from the first system; each processing device of the first system and the second system includes a survival monitoring unit configured to monitor a failure of the each processing device or the each LAN based on a device time-out for confirming survival of the each processing device and a route time-out for confirming survival of the each LAN set to be longer than the device time-out.

In accordance with an embodiment, a method includes determining whether a frame received from a communication bus is encoded according to a particular communication protocol and is addressed to a particular electronic device; increasing a frame count value when the frame is encoded according to the particular communication protocol and is addressed to the particular electronic device based on the determination, wherein increasing the frame count value comprises increasing a count of a modular arithmetic counter circuit having a first bit depth, and the frame count value is constrained to a modulus value of the modular arithmetic counter circuit; setting a frame count status bit based on comparing the frame count value to threshold values, and transmitting a frame comprising the frame counter status bit over the communication bus, and resetting the frame count value at an end of a monitoring time interval.
