摘要： An Ethernet protection switching method based on a change in link status in a link aggregation sublayer is disclosed. If an Ethernet link aggregation sublayer is present on an Ethernet connection path, a link aggregation sublayer Management Entity Group (MEG) end point is assigned to the Ethernet link aggregation sublayer to generate a link aggregation message for Ethernet connection management and protection switching. When a change in link status is detected in the Ethernet link aggregation sublayer, the link-aggregation-sublayer MEG end point generates and sends the link aggregation message to an MEG end point performing Ethernet connection management and protection switching. Adequate Ethernet protection switching may be performed even in the presence of the link aggregation sublayer.

摘要： A method for protection switching in a shared node where protection resources of a plurality of end-to-end linear protection domain are shared is provided. The shared node receives a first protection switching event message notifying that a protection switching event occurs from a first node of a first end-to-end linear protection domain, and determines whether to prohibit protection switching on a second end-to-end linear protection domain by comparing a priority of the first end-to-end linear protection domain with a priority of the second end-to-end linear protection domain.
摘要翻译：提供了共享节点中的保护切换的方法，其中共享多个端到端线性保护域的保护资源。共享节点接收第一保护切换事件消息，通知从第一端对端线性保护域的第一节点发生保护倒换事件，并且确定是否禁止对第二端对端线性保护进行保护切换通过将第一端到端线性保护域的优先级与第二端对端线性保护域的优先级进行比较来实现。
