摘要： The invention relates to an Ethernet ring node (100) comprising a plurality of ports including at least two ring ports and at least one non-ring port. The Ethernet ring node comprises a multicast list including information on which port multicast traffic belonging to a multicast group should be sent. A control unit is provided configured to control a traffic distribution of multicast traffic to the different ports of the Ethernet ring node based on the information provided in the multicast list. Furthermore, a detector is provided detecting a topology change of the Ethernet ring in which the Ethernet ring node is provided. When such a topology change is detected, all multicast traffic is transmitted to the at least two ring ports for a predefined period of time, and multicast traffic transmitted to the non-ring ports is transmitted in accordance with the information provided in the multicast list.

摘要： For performing link adaptation in an Ethernet ring protection system, a link management controller (180) determines a ring protection state of an Ethernet protection ring. Further, the link management controller (180) adapts bandwidth of a link (25) of the Ethernet protection ring. Depending on the adapted bandwidth and the determined ring protection state, the link management controller (180) deactivates the link of the Ethernet protection ring. In particular, if the adapted bandwidth is below a threshold value and the ring protection state indicates that there is no link failure in the Ethernet protection ring, the link management controller (180) may deactivate the link (25).
摘要翻译：为了在以太网环网保护系统中执行链路自适应，链路管理控制器（180）确定以太网保护环的环路保护状态。此外，链路管理控制器（180）适配以太网保护环的链路（25）的带宽。根据适应的带宽和确定的环路保护状态，链路管理控制器（180）使以太网保护环的链路无效。特别地，如果适配带宽低于阈值，并且环路保护状态表示以太网保护环中没有链路故障，则链路管理控制器（180）可以停用链路（25）。
