Abstract
The invention discloses a method for controlling a ring in an Ethernet ring network system and a device thereof. The method comprises the following steps: the detected messages are sent periodically at a service sending terminal of a link circuit; the number of the detected messages received by the service receiving terminal in one period is counted; according to the counted number of the detected messages, the performance of the link circuit is judged and if the performance of the link circuit falls to the preset threshold value, the state of the link circuit is set as a failure state; the Ethernet ring network system carries out link circuit switching according to the condition that the link circuit is in failure state. The application of the invention ensures that when the ring performance falls to a certain threshold value, transmission link circuits are distributed again, and the service in a worse link circuit is forwarded to a healthy link circuit, which avoids degradation of performance in the Ethernet ring network domain, therefore, the application capability of the Ethernet ring network in the actual networking is improved.
