Abstract: 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).

Abstract: 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.

Abstract: According to embodiments of the invention, a first ring node is arranged to protect against loops in an Ethernet ring by performing Ethernet ring protection (ERP) according to an Ethernet ring protection protocol (ERP) standard. The first ring node is located directly adjacent to at least one second ring node in the Ethernet ring which is not configured to perform ERP according to the same ERP protocol standard. The first ring node is configured to, upon detection of a link failure or recovery event in the Ethernet ring resulting in a flush operation of the filtering database (FDB) in the first ring node in accordance with the ERP protocol standard, send a message to the at least one second ring node which is operable to cause said at least one second ring node to perform a flush operation of its filtering database (FDB). Embodiments of the invention also include an Ethernet ring, a broadband communications network and methods for use in the first ring node and in the Ethernet ring.
