Method and device for dynamic synchronous transfer mode in a dual ring topology

摘要

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