A dynamic synchronous transfer mode network (10) that comprises two ring topologies (12, 14) having opposite fiber direction. The first dynamic synchronous transfer mode ring topology (12) has a plurality of nodes (60-70) for receiving and transmitting frames. The time slots are dynamically allocated to the nodes (60-70) and the first ring topology (12) is adapted to transmit frames only in a first fiber direction (D1). The second dynamic synchronous transfer mode ring topology (14) also has a plurality of nodes (60- 70) in common with the first ring topology (12). The second ring topology (14) only transmits frames in a second direction (D2) that is opposite the first fiber direction (D1).

Un réseau (10) en mode de transfert synchrone dynamique comprend deux topologies en anneau (12, 14) ayant un sens de fibre opposé. La première topologie en anneau (12) en mode de transfert synchrone dynamique comprend une pluralité de noeuds (60-70) destinés à recevoir et à transmettre des blocs. Les tranches de temps sont affectées dynamiquement aux noeuds (60-70) et la première topologie en anneau (12) est adaptée pour transmettre des blocs uniquement dans un premier sens (D1) de fibre. La seconde topologie en anneau (14) en mode de transfert synchrone dynamique comprend également une pluralité de noeuds (60-70) en commun avec la première topologie en anneau (12). La seconde topologie en anneau (14) ne transmet les blocs que dans un second sens (D2) opposé au premier sens (D1) de fibre.
