Abstract: Embodiments of the present invention disclose an Ethernet ring protection switching method, node, and system. In an Ethernet ring protection switching method is disclosed, it is determined whether the current link is a lower-bandwidth link according to bandwidth information of a current link and bandwidth information of another link on a ring. If the current link is a lower-bandwidth link, a port corresponding to the current link is blocked.

Abstract translation: 本发明的实施例公开了一种以太网环保护交换方法，节点和系统。 在以太网环路保护切换方法中，根据当前链路的带宽信息和环上的其他链路的带宽信息，确定当前链路是否为低带宽链路。 如果当前链路是低带宽链路，则与当前链路相对应的端口被阻塞。
