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.
Claims15
A communication method applied to a flexible Ethernet (FlexE) cross ring network,
- the method comprising:
- determining, by a first network device included in the FlexE cross ring network, that a third FlexE group between the first network device and a third network device is faulty, wherein the FlexE cross ring network further comprises a second network device and the third network device, the first network device is adjacent to the second network device, the first network device is adjacent to the third network device, wherein there is a first FlexE group and a second FlexE group between the first network device and the second network device, wherein the first FlexE group is used to carry a first client, the second FlexE group is used to carry a second client, and the third FlexE group is used to carry a third client;
- deleting, by the first network device, a FlexE cross between the first client and the third client;
- and
- establishing, by the first network device, a FlexE cross between the first client and the second client.
A communications apparatus;
- applied to a ring network, wherein the ring network is a flexible Ethernet (FlexE) cross ring, the FlexE cross ring comprises a first network device, a second network device, and a third network device, the first network device is adjacent to the second network device, the first network device is adjacent to the third network device, there is a first FlexE group and a second FlexE group between the first network device and the second network device, the first FlexE group is used to carry a first client, the second FlexE group is used to carry a second client, there is a third FlexE group between the first network device and the third network device, and the third FlexE group is used to carry a third client, wherein the communications apparatus is configured in the first network device and comprises:
- a memory, wherein the memory comprises a computer-readable instruction;
- and
- a processor connected to the memory, wherein the processor is configured to execute the computer-readable instruction;
- to perform the following operations:
- determining that the third FlexE group is faulty;
- deleting a FlexE cross between the first client and the third client;
- and
- establishing a FlexE cross between the first client and the second client.
A computer-readable storage medium, wherein the computer-readable storage medium stores an instruction, and when the instruction is run on a computer, the computer is enabled to perform a method comprising:
- determining that a third flexible Ethernet (FlexE) group between a first network device and a third network device is faulty, wherein the first network device is adjacent to a second network device, and the first network device is adjacent to the third network device, wherein there is a first FlexE group and a second FlexE group between the first network device and the second network device, wherein the first FlexE group is used to carry a first client, the second FlexE group is used to carry a second client, and the third FlexE group is used to carry a third client;
- deleting a FlexE cross between the first client and the third client;
- and
- establishing a FlexE cross between the first client and the second client.
