Abstract
The invention relates to a method for operating a communication network (), in particular an Ethernet network. Network devices () which are coupled to the network comprise a switch device (), a first and a second control device () which are coupled to the switch device (), and the switch device () comprises for the first and the second control device () a respective input port () and emitter port () for sending and receiving data via the communication network (). Ring-shaped communication paths for data are provided so that redundant data can be transmitted in different directions and checked for consistency. An improved protection against failure and error analysis in the event of transmission errors are ensured by the ring-shaped structure using bidirectional communication paths. The invention further relates to a network arrangement () comprising several corresponding network devices () which operate according to the method.
