Embodiment 1

[0052] This embodiment is a function freezing method in an automatic switching optical network, including the following steps:

[0053] 201. The control node receives a freeze command ASON_FREEZE_NODE: 3, 1, 11, 60 (for a version that supports freeze modules and freeze delays) from the management plane. In this command, parameter 3 indicates that the ASON node ID of the current ASON control node is 3, parameter 1 indicates that the freezing type is freezing, parameter 11 indicates freezing the TAP module, and parameter 60 indicates that the freezing delay is 60 seconds. Afterwards, the validity of the parameters is verified, and a success response is returned to the management plane after the verification is successful.

[0054] 202. The control node judges whether the freeze command contains a freeze module parameter.

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

[0056]If it is not Normal, read the module dependency table and search for the upp...

Embodiment 2

[0071] Similar to Embodiment 1, this embodiment assumes that the freezing command received from the management plane is: ASON_FREEZE_NODE: 3, 2, 0, 0 (wherein, parameter 3 indicates that the ASON node ID of the current ASON control node is 3; parameter 2 indicates the freezing type unfreeze; parameter 0 indicates that the frozen module is Normal, and unfreezes the entire control node; the last parameter 0 indicates that the freezing delay is 0 seconds, and unfreezes immediately). After the parameter verification is successful, a success 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, and there is no need to start the delay timer. Immediately send a thawing preparation notification message to each module, and the delay parameter is 0.

[0073] After each module receives the unfreezing notification message, it resumes its normal processing, and clea...

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 system is released, and the flexibility is enhanced.

Description

technical field [0001] The invention relates to the field of automatic switching optical network, in particular to a method for freezing / thawing function (module, protocol) in automatic switching optical network. Background technique [0002] In the field of Automatically Switched Optical Network (ASON, commonly known as intelligent optical network), the ASON control node (that is, the so-called smart device) is responsible for the connection management and control of the entire network, and more processing protocols are running on it. . During the operation of the control node, it may be required to suspend a certain part of the function or the overall function of the external response, but still need to continue to maintain the existing information, that is, it is required to freeze; or after a certain part of the function or the overall function is frozen, it is required to restart To accept a new external request and resume normal operation, it is required to unfreeze. ...
