Embodiment 1

[0052] This embodiment is a method for freezing functions in an automatic switching optical network, which includes the following steps:

[0053] 201. The control node receives a freeze command ASON_FREEZE_NODE of the management plane: 3, 1, 11, 60 (for a version that supports freezing modules and freezing delay). In this command, parameter 3 indicates that the ASON node identifier of the current ASON control node is 3, parameter 1 indicates that the freezing type is frozen, parameter 11 indicates that the TAP module is frozen, and parameter 60 indicates that the freezing delay is 60 seconds. After that, the parameter validity check is performed, and a successful response is returned to the management plane after the check is successful.

[0054] 202. The control node judges whether the freezing module parameter is included in the freezing command.

[0055] If there is a frozen module parameter, judge whether it is Normal;

[0056] If it is not Normal, read the module dependency tabl...

Embodiment 2

[0071] Similar to Embodiment 1, this embodiment assumes that the freeze command received from the management plane is: ASON_FREEZE_NODE: 3, 2, 0, 0 (where parameter 3 indicates that the ASON node identifier of the current ASON control node is 3; parameter 2 indicates the freezing type It is thawing; parameter 0 means that the freezing module is Normal, and the entire control node is thawed; the last parameter 0 means that the freezing delay is 0 seconds, and it is thawed immediately). After successful parameter verification, a successful response is returned to the management plane.

[0072] Since it is required to unfreeze the entire control node immediately, there is no need to read the module dependency table or start the delay timer. Send a thaw preparation notification message to each module immediately, and the delay parameter is 0.

[0073] After each module receives the unfreeze notification message, it resumes its normal processing, and will freeze the backlog of notifica...

Abstract

The invention discloses a function freezing / defreezing method in the automatically switched optical network. The method comprises: (1) the control node detects the freezing parameter in the freezing command, to determine the freezing type is freezing or defreezing; (2) to judge whether the freezing module parameter is contained in the freezing command; if the freezing module parameter is not contained, enter Step (3), otherwise enter Step (4); (3) to freeze / defreeze the whole control node according to the freezing type, and the process is finished; (4) to freeze / defreeze the corresponding module and the module in the previous layer according to the freezing type, the freezing module and the module dependency relationship table, and the process is finished. The adoption of the invention can realize the freezing / defreezing of the whole function of partial function of the control node; when the freezing / defreezing is performed during the normal running of the system, the whole system function can't be influenced; the adoption of the divided function freezing strategy, the freezing module can be expanded at the proper time, the impact of the whole node freezing to the systemis released, and the flexibility is enhanced.

Description

Technical field [0001] The present invention relates to the field of automatic switching optical networks, in particular to a method for freezing / unfreezing functions (modules, protocols) in automatic switching optical networks. Background technique [0002] In the field of Automatically Switched Optical Network (ASON, commonly known as intelligent optical network), ASON control nodes (commonly known as smart devices) are responsible for the connection management and control of the entire network, and more processing protocols are running on them . During the operation of the control node, there may be an external response requesting to suspend a certain part of the function or the whole function, but still need to maintain the existing information, that is, it is required to be frozen; or it is required to restart after a certain part of the function or the whole function is frozen. When a new external request is accepted and normal operation is resumed, it is required to unfre...
