NETWORK AND EXPANSION UNIT AND METHOD FOR OPERATING A NETWORK

摘要

The invention relates to a network (3), in particular an Ethernet network, comprising as network elements at least two network components (4A, 4B) that are interconnected by means of a network transmission line (2). According to the invention, at least one expansion unit (1) having two external ports (A, B) is disposed in the network line (2) for extending the scope thereof, wherein the expansion unit (1) forwards a failure of the network transmission line (2) at one of the ports (A, B) thereof to a port (B or A) of the next subsequent network element (network component 4A or 4B). The invention further relates to an expansion unit (1) and to a method for operating a network (3).
