Abstract
The invention relates to a local area network operating according to the asynchronous transfer mode (ATM) for transmitting cells, comprising a plurality of network interfaces. At least two ring systems are provided which comprise each two network interfaces (85, 89; 86, 90) and respective bridge connections (83, 84; 87, 88). A first network interface (85) of a first ring system and a first network interface (86) of a second ring system are coupled via first bridge connections (83, 84) to the two ring systems for transporting the cell stream to the two ring systems, and a second network interface (89) of the first ring system and a second network interface (90) of the second ring system are coupled via second bridge connections (87, 88) for transporting the cell stream to the two ring systems.
