Abstract

An intent decomposition method includes sending, by a first network device, a first sub-intent target value to a second network device. The method also includes receiving, by the first network device, a first message from the second network device. The first message is used to indicate that the first sub-intent target value is not achieved by the second device. The first message includes a first measurement value of the second network device. The method further includes re-decomposing, by the first network device, an intent based on the first measurement value, and sending first sub-intent target values obtained through re-decomposition to the second network device and one or more other network devices different from the first network device and the second network device until all the first sub-intent target values obtained through re-decomposition are achieved or none of the first sub-intent target values obtained through re-decomposition are achieved.

First claim

What is claimed is:

1. An intent decomposition method, comprising:
sending, by a first network device, a first sub-intent target value to a second network device;
receiving, by the first network device, a first message from the second network device, wherein the first message is used to indicate that the first sub-intent target value sent to the second network device is not achieved by the second device and the first message comprises a first measurement value of the second network device; and
re-decomposing, by the first network device, an intent based on the first measurement value, and sending first sub-intent target values obtained through re-decomposition to the second network device and one or more other network devices different from the first network device and the second network device until all the first sub-intent target values obtained through re-decomposition are achieved by the second network device and the one or more other network devices or none of the first sub-intent target values obtained through re-decomposition are achieved by the second network device and the one or more other network devices.

2. The intent decomposition method according to claim 1 , wherein before the sending, by the first network device, the first sub-intent target value to the second network device, the method further comprises:
receiving, by the first network device, a total intent target value configured by a third network device different from the second network device and the one or more other network devices; and
decomposing, by the first network device, the total intent target value to obtain the first sub-intent target value sent to the second network device by the first network device.

3. The intent decomposition method according to claim 2 , wherein the total intent target value is related to a quantity of execution devices, and each execution device is a network device configured to perform an intent operation.

4. The intent decomposition method according to claim 3 , wherein the total intent target value and the first sub-intent target value are absolute values or relative values, the absolute value is not related to state information of the execution device, and the relative value is related to the state information of the execution device.

5. The intent decomposition method according to claim 4 , wherein the method further comprises:
before re-decomposing, by the first network device, the intent based on the first measurement value, the sending, by the first network device, a corresponding first sub-intent target value to the one or more other network devices; and
receiving, by the first network device, a second message from one of the one or more other network devices, wherein the second message is used to indicate that the first sub-intent target value corresponding to the one of the one or more other network devices is achieved,
the second message comprises a second measurement value of the one of the one or more other network devices,
the second measurement value is obtained through prediction based on the state information of one of the execution devices,
the total intent target value and the first sub-intent target value are relative values,
at least one of the first message or the second message further comprises a third measurement value that is of the one of the execution devices before the one of the execution devices executes a first instruction, and
the re-decomposing, by the first network device, the intent based on the first measurement value comprises:
re-decomposing, by the first network device, the intent based on the first measurement value and the third measurement value.

6. The intent decomposition method according to claim 1 , wherein before the sending, by the first network device, the first sub-intent target value to the second network device, the method further comprises:
receiving, by the first network device, a second sub-intent target value sent by a third network device different from the second network device and the one or more other network devices, wherein the second sub-intent target value is obtained by the third network device by decomposing a total intent target value; and
decomposing, by the first network device, the second sub-intent target value to obtain the first sub-intent target value sent to the second network device by the first network device.

7. The intent decomposition method according to claim 6 , wherein the method further comprises:
in response to all the first sub-intent target values obtained by re-decomposition being achieved, sending, by the first network device, a success message to the third network device, wherein the success message is used to indicate that the total intent target value is achieved; or
in response to none of the first sub-intent target values obtained by re-decomposition being achieved, sending, by the first network device, a failure message to the third network device, wherein the failure message is used to indicate that the total intent target value is not achieved, the failure message comprises a second measurement value of the first network device, and the second measurement value is determined based on the first measurement value of the second network device.

8. The intent decomposition method according to claim 7 , wherein the success message comprises a third measurement value of the first network device, and the third measurement value is obtained through prediction based on state information of an execution device configured to perform an intent operation.

9. The intent decomposition method according to claim 8 , wherein the execution device is one of multiple execution devices, the total intent target value is related to a quantity of the execution devices, and at least one of the success message or the failure message comprises the quantity of the execution devices.

10. The intent decomposition method according to claim 7 , wherein the total intent target value and the first sub-intent target value are relative values, and at least one of the success message or the failure message comprises a third measurement value that is of an execution device before the execution device executes a first instruction.

11. The intent decomposition method according to claim 1 , wherein the method further comprises:
before re-decomposing, by the first network device, the intent based on the first measurement value, sending, by the first network device, a corresponding first sub-intent target value to the one or more other network devices; and
receiving, by the first network device, a second message from one of the one or more other network devices, wherein the second message is used to indicate that the first sub-intent target value corresponding to the one of the one or more other network devices is achieved.

12. The intent decomposition method according to claim 11 , wherein the second message comprises a second measurement value of the one of the one or more other network devices, the second measurement value is obtained through prediction based on state information of an execution device in communication with the one of the one or more other network devices, and
