Abstract

A network, in particular an Ethernet network, contains as network elements at least two network components that are interconnected by a network transmission line. Accordingly, at least one expansion unit having two external ports is disposed in the network line for extending the scope thereof, wherein the expansion unit forwards a failure of the network transmission line at one of the ports thereof to a port of the next subsequent network element.
