Claim Text:
1. An Ethernet ring protection switching method, comprising: obtaining, by a node, bandwidth information of a first link on an Ethernet ring on which the node is located, and determining that bandwidth of the first link changes, wherein there is at least one Ethernet ring protection instance on the Ethernet ring; determining, by the node, ports of the node, wherein the at least one Ethernet ring protection instance passes through the ports; and querying, by the node, pre-configured correspondence between bandwidth information and switching information of each link on the Ethernet ring, and executing, through the ports of the node, a switching operation corresponding to the bandwidth information of the first link, wherein the node stores the correspondence between the bandwidth information and the switching information of each link on the Ethernet ring, and the correspondence between the bandwidth information and the switching information of each link on the Ethernet ring comprises: correspondence between a bandwidth value and at the least one Ethernet ring protection instance and a switching operation that needs to be executed through the ports of the node.
