Network device, communication system and method for the network device

A method for a network device comprising a first input interface, a first output interface, and a second output interface, wherein the network device is configured to change between a first state, in which the network device is configured to provide temporal communication redundancy, and a second state, in which the network device is configured to provide spatial communication redundancy, and wherein the method comprising the steps:

• a) Receiving a first input message via the first input interface;
• b) Generating each of a first output message and a second output message based on the first input message, wherein the first output message and the second output message each represent the same content as the first input message;
• c) Changing the network device to a selected one of the first state or the second state;
• d) Transmitting, via a selected one of the first output interface or the second output interface while in the first state, both the first output message and the second output message, with transmission of the first output message being offset in time with respect to transmission of the second output message;
• and
• e) Transmitting, while in the second state, the first output message via the first output interface and the second output message via the second output interface.
