Abstract

Systems and methods are provided for operating a network arrangement including multiple network devices that are coupled to each other in a ring structure. Each network device includes a control device and a switch device with at least two ports for coupling to a communication path. During operation, at least two VLANs are simultaneously provided in the ring structure, and the sending of a data packet from the control device of a selected network device is performed via a port of the switch device in one of the two VLANs. In order to achieve this, the other port of the switch device of the selected network device is deactivated for the one VLAN. By using two VLANs, a redundant and reliable data transmission may be achieved. A destabilization of the VLANs in the network ring is prevented by the targeted deactivation of specific ports of the sending network device.
