Abstract:
A local area network operating in the asynchronous transfer mode (ATM) for transmitting cells, comprising a plurality of network interfaces, characterized in that at least two ring systems comprising each two network interfaces (85, 89; 86, 90) are provided which ring systems comprise each at least one bridge connection (83, 84; 87, 88) and in that a first network interface (85) of a first ring system and a first network interface (86) of a second ring system are coupled via at least a first bridge connection (83, 84) for transmitting the cell stream between 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 at least a second bridge connection (87, 88) for conveying the cell stream between the two ring systems.
