Problems solved by technology

This approach has obvious shortcomings: when the required function sets are quite different, it is often necessary to maintain multiple versions at the same time, or even to develop multiple different versions simultaneously, which increases the development cost and cost; once the version is determined, It is often difficult to change, and such changes generally require a high cost

Embodiment 1

[0074] refer to figure 1 As shown in FIG. 2 , when the control plane is started or restarted, each module of the control plane is registered to realize the start or restart of the control plane.

[0075] Step S101: Read the module registry.

[0076] When the control plane starts or restarts, after the basic modules (such as: operating system encapsulation module, database module, main control module, communication module, connection control module, link resource management module, etc.) start up, call the module registration method, read Module Registry.

[0077] In this example, assuming that the basic module is started and the module registration method is called, the module relationship table read is as follows (see Figure 2):

Embodiment 2

[0106] During the normal operation of the control plane, the optional modules in the control plane are stopped to realize the dynamic unloading of the control plane modules.

[0107] refer to image 3 and Figure 4 As shown, during the normal operation of the control plane, the process of stopping the module is described as follows.

[0108] Step S301: Read the module registry.

[0109] When the control plane is running normally, when a command to stop a module is received, the module registration method is called to read the module registry.

[0110] In this example (see Figure 4 ), assuming that the control plane receives a command to stop the DA module (module ID is 34), the main control module calls the module registration method, and the module relationship table read is as follows:

[0111] ##Module ID

Embodiment 3

[0136] During the normal operation of the control plane, the method of the present invention can be used to start the optional modules in the control plane to realize the dynamic loading of the control plane modules.

[0137] refer to Figure 5 and Image 6 As shown in , during the normal operation of the control plane, the detailed description of the process of starting a selected module is as follows.

[0138] Step S501: Read the module registry.

[0139] When the control plane is running normally, when a command to start a selected module is received, the module registration method is called to read the module registry.

[0140] In this example (see Image 6 ), assuming that the control plane receives the command to start the LMP module (module ID is 29) (assuming that the LMP module is not started), the main control module calls the module registration method, and the module relationship table read is as follows:

[0141] ##Module ID

Abstract

The invention discloses a method for automatically control module registration in a switching optical network. The method comprises the processes: an identification of the control plane module is distributed; a parameter of a module registration list is confirmed according to needs of a user; the module registration list is filled by the parameter of the module registration list and the module registration list is used in the start or restart process of the control plane, or in the process of stopping module or restarting module in running process of the control plane. The invention also discloses a method for managing an ASON control plane module by using the module registration list. The invention can be used for starting and restarting the control plane, as well as stopping the module and restarting part of the module in the running process of the control plane. The invention has the advantages of flexible selection of function set and flexible customization of demanded module number. Different versions and function sets can be acquired by maintaining a complete version and filling different module registration lists.

Description

technical field [0001] The invention relates to the field of automatic switching optical network, in particular to a method for registering a control module or component in an automatic switching optical network and an application method thereof. Background technique [0002] In the field of Automatically Switched Optical Network (ASON, commonly known as intelligent optical network), the ASON control node is responsible for the connection management and control of the entire network, and many processing protocols are running on it. For the convenience of maintenance and management and the clarity of functions, the entire control plane function is usually divided into multiple different modules (or components), and specific functions are realized through certain combinations. During the operation of the control plane, there may be a need to add modules that have not been running before; or due to hardware constraints, all ASON modules cannot be loaded; or due to business reas...
