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)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Ring protection state aware bandwidth adaptation","description":"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.
