Abstract

The present invention provides a method for processing a switch control command for solving the problem that consistency of data of the network device and the network management is unable to be kept in the process of processing the switch control command in the prior art. This method includes: when a priority of obtained trigger information is higher than a priority of a switch control command, discarding the switch control command (103); and reporting the discarded switch control command to a control system which manages the network device (104). The present invention further provides an device for processing a switch control command.

Claims

1. A method for processing a switch control command comprising:

discarding a switch control command when a priority of obtained trigger information is higher than that of the switch control command; and

reporting the discarded switch control command to a control system which manages a network device.

2. The method according to claim 1, wherein when the obtained trigger information is obtained alert information or received remote Automatic Protection Switching (APS) information, the discarding the switch control command comprises:

clearing a unit and protection state value that the switch control command indicates.

3. The method according to claim 2, wherein when the obtained trigger information is the received remote APS information, the method further comprising:

verifying legality of the received remote APS information.

4. The method according to claim 1, wherein when the obtained trigger information is a switch control command, the discarding the switch control command comprises:

resetting a unit and protection state value that the switch control command indicates based on the sent switch control command.

5. The method according to claim 1, wherein the discarding the switch control command further comprises:

storing the switch control command into a reporting buffer.

6. The method according to claim 5, wherein the reporting the discarded switch control command to the control system which manages the network device comprises:

querying periodically whether there is the switch control command in the reporting buffer;

when there is the switch control command in the reporting buffer, packing discarding information of the switch control command and reporting the information to the control system which manages the network device via a communication interface.

13. The method according to claim 2, wherein the discarding the switch control command further comprises:

storing the switch control command into a reporting buffer.

14. The method according to claim 3, wherein the discarding the switch control command further comprises:

storing the switch control command into a reporting buffer.

15. The method according to claim 4, wherein the discarding the switch control command further comprises:

storing the switch control command into a reporting buffer.

7. An apparatus for processing a switch control command comprising an obtaining unit, a comparing unit, a discarding unit and a reporting unit;

wherein

the obtaining unit is configured to obtain trigger information;

the comparing unit is configured to compare a priority of the obtained trigger information with that of a switch control command;

the discarding unit is configured to discard the switch control command; and

the reporting unit is configured to report the discarded switch control command to a control system which manages a network device.

8. The apparatus according to claim 7, wherein the obtaining unit comprises an obtaining sub-unit and a first receiving sub-unit, wherein

the obtaining sub-unit is configured to obtain alert information;

and

the first receiving sub unit is configured to receive remote APS information;

accordingly, the discarding unit comprises a clearing sub-unit configured to clear a unit and protection state value that the switch control command indicates.

9. The apparatus according to claim 8, further comprising:

a verifying unit configured to verify legality of the received remote APS information.

10. The apparatus according to claim 7, wherein the obtaining unit comprises:

a second receiving sub-unit configured to receive a switch control command sent by a network manager;

accordingly, the discarding unit comprising a resetting sub-unit configured to reset a unit and protection state value that the switch control command indicates based on the sent switch control command.

11. The apparatus according to claim 7, wherein the discarding unit further comprises:

a storage sub-unit configured to store the switch control command into a reporting buffer.

12. The apparatus according to claim 11, wherein the reporting unit comprises a query sub-unit and an packing and reporting sub-unit;

wherein

the query sub-unit is configured to query periodically whether there is the switch control command in the reporting buffer; and

the packing and reporting sub-unit is configured to pack discarding information of the switch control command when there is the switch control command in the reporting buffer and report the information to a control system which manages a network device via a communication interface.

16. The apparatus according to claim 8, wherein the discarding unit further comprises:

a storage sub-unit configured to store the switch control command into a reporting buffer.

17. The apparatus according to claim 9, wherein the discarding unit further comprises:

a storage sub-unit configured to store the switch control command into a reporting buffer.

18. The apparatus according to claim 10, wherein the discarding unit further comprises:

a storage sub-unit configured to store the switch control command into a reporting buffer.
