Abstract: This application provides a method for transmitting data on a ring network. The ring network includes two adjacent FlexE cross-connection rings, each FlexE cross-connection ring includes at least three nodes, the two FlexE cross-connection rings have at least one common node, the common node carries a cross-ring end-to-end working path, and each of the two FlexE cross-connection rings includes one ring-shaped protection path. Because there is a protection path between any two adjacent nodes in the two FlexE cross-connection rings, if a link fault occurs in the common node, a node adjacent to the common node may transmit data from one FlexE cross-connection ring to another FlexE cross-connection ring by using the ring-shaped protection path. Therefore, reliability of the ring network including the at least two FlexE cross-connection rings is improved.

Abstract: This application provides a method for transmitting data on a FlexE cross ring. At least three nodes forming the FlexE cross ring include a first node, a second node, and a third node. There is a protection path and a working path between any two adjacent nodes, and the protection path is a backup path of the working path. In the solution provided in this application, the protection path between nodes is established on the FlexE cross ring. In this way, when a FlexE group between any two adjacent nodes on the FlexE cross ring is faulty, a node on the FlexE cross ring can still complete data forwarding.
