<p>The present invention relates to a system and a method for protecting an interconnection between two ring networks (1, 2). Each ring network (1, 2) comprises two communication paths (3, 4, 5, 6) and at least one node connected to both communication paths (3, 4, 5, 6). The two ring networks (1, 2) are interconnected via two gateways (7, 8). Each gateway (7, 8) is arranged to receive traffic from both communication paths (3, 4, 5, 6) on one ring network (1, 2) and to transmit said traffic to the other ring network (1, 2) on the communication path (3, 4, 5, 6) directed from the other gateway (7, 8). According to the invention the traffic is stopped in both directions in an inactive segment (13a, 13b) on each ring network, so that a node situated on a ring network (1, 2) receives traffic from only one of the two gateways (7, 8).</p> |
