Description

Association management method in optical communication system {A METHOD OF MANAGING ASSOCIATION FOR OPTICAL COMMUNICATION SYSTEM}

The present invention relates to a method for efficiently managing associations for smooth data communication between a manager and an agent in an optical communication system.

One optical cable used as a communication line in an optical communication system has a capacity of data transmission capable of simultaneously speaking subscribers of about 2,000 to 30,000 lines or more of ordinary copper (Cu) telephone line subscribers.

In general, copper (Cu) telecommunication lines are not only susceptible to moisture, but there is a great risk of data distortion or loss due to external factors such as static electricity or short circuit. Transmission is possible, and as one optical communication line, there is an advantage that can replace the copper communication line of about 30,000 lines as described above, the use thereof is gradually increasing.

As described above, a centralized management system (NMS: Network Management System or EMS) for operating an optical signal transmission device that transmits and receives a large amount of data messages to an optical cable made of optical fiber, that is, a synchronous optical communication system normally. The maintenance problem by the Element Management System is very important, and as the operation information required between each device and the device, it is very important to quickly send and receive data messages.

An optical communication system includes a manager or a user who generates and manages a control command to secure data necessary for normal operation of the system, and executes and executes a command of the manager and displays the result of the manager ( There is a preliminary process called association which confirms each other's existence in order to help the manager and agent and agent to communicate smoothly with each other. Only when association, which is a process, is established, an instruction is transmitted from the manager to the agent.

Conventional techniques used to smoothly manage and maintain such a large-capacity optical communication system in a centralized management device (NMS) are associations that confirm the existence of each other between a manager and an agent. ) Is allocated indefinitely as long as the resources of the optical communication system allow, but when the expansion or expansion is made according to the characteristics of the optical communication system, the synchronous optical transmission terminal (NE) network to be managed increases, and the centralized management device (NMS) is limited by the available resources, there was a problem that can not establish the necessary association by the association that was previously used, but not used immediately or frequently used.

Thus, there has been a problem of lowering reliability in operating and maintaining a large capacity optical communication system.

The present invention creates a list of associations in a central management unit (NMS) of the optical communication system as described above, deletes the oldest ones or the ones that are not frequently used, and records the associations that are to be used at present. The goal is to provide a way to make it.

In order to achieve the above object, the present invention records an instruction authorized from an administrator of an optical communication system in a command waiting list, and obtains an execution level of an instruction that can be safely and fairly performed by all administrators of the system. The first process of deleting an association that is older than the performance level from the administrator's execution list and the old or infrequently used association, and extracts the instruction to be processed from the standby instruction list, and adds the instruction to the association list recorded in the administrator's performance list. A method for managing association in an optical communication system, comprising a second process of deleting an association of at least a level that can be performed by the system and then recording an association of the instruction to be processed, if there is no association of the instruction to be processed. Scoop It shall be.

Referring to the accompanying drawings, the association management method in the optical communication system according to the present invention, in the centralized management device (NMS) of the optical communication system, the value of the association pool (Association Pool) that is the value that can form a maximum association ( Value) and the first step (S1) of setting the safety pin (Safe Pin) value,

A second step (S2) of returning to the first step (S1) if it is not authorized by judging whether the command is authorized from a manager that generates a command for maintenance of the optical communication system;

A third step S3 of recording the command received from the second step S2 in the waiting operation list shown in FIG. 2;

A fourth step S4 of obtaining a command performance level Water Mark using the value set in the first step S1,

A fifth step (S5) in which the numerical total level of the association recorded in the manager's association list is greater than the water mark obtained in the fourth step (S5); )Wow,

If it is determined in step 5 that the numerical level of the association recorded in the to-do list is greater than the value of the water level, the association with the oldest time stamp of the to-do list is determined. A sixth step (S6) of deleting the association;

A seventh step S7 of feeding back to the third step S3 when there are some commands not received in the waiting command list among the commands received from the second step S2;

An eighth step S8 of fetching a command to be processed from the waiting operation list;

A ninth step S9 of determining whether an instruction fetched from the command list by the eighth step S8 is recorded with an association with the agent in contrast to an association recorded in the execution list;

When the association of the command is not recorded in the to-do list in the ninth step S9, the numerical level of the association recorded in the to-do list of the corresponding manager is to be performed by the central management unit (NMS). A tenth step (S10) of determining whether the number is greater than the numeric level of association;

If it is determined in the tenth step (S10) is the eleventh step (S11) to delete the association (Oldest time stamp) is the oldest from the performance list of the administrator;

In order to execute the command fetched from the eighth step S8, a preliminary association is established to confirm the existence of a manager and an agent and to facilitate smooth communication. A twelfth step (S12) of recording in the to-do list of the Manager and recording the time stamp as '1' and at the same time increasing and recording the time-stamp value of another association of the to-do list one by one;

When the corresponding association of the command is recorded in the execution list of the manager in the ninth step S9, the corresponding association time stamp value of the execution list is 1, and the time stamp values of the remaining associations are in order. A thirteenth step S13 for sorting in ascending order;

In the case of a command that is drawn out and not processed in the waiting operation list, the process returns to the eighth step S8 to feed back to the eighth step S8 to repeat the above process. do.

Hereinafter, with reference to the accompanying drawings of the present invention of the above configuration will be described in detail.

In the central management system (NMS) of the optical communication system, which smoothly operates and maintains large data transmission by large communication lines, there are a number of managers or users who issue commands for operation and maintenance. As described above, an active manager is recorded and managed in a separate manager list as shown in FIG. 1.

In addition, as illustrated in FIGS. 2 and 3, the centralized management device NMS temporarily stores and manages the commands generated by the manager until the command is transmitted to the manager. A list of waiting commands and associations, which are a type of software protocol that allows each manager to check the existence of each other and communicate smoothly with each other. There is a to-do list that is archived and managed.

In addition, the centralized management device (NMS), although the number of associations that can be processed at one time may vary slightly depending on the system configuration, there is some limitation.

By limiting the number of commands input from the administrator to the capacity of the system to a certain extent, the safety pin is set in the first step S1 in order to have fairness in resource operation and resource distribution. Although the value of the maximum association pool is set, this is slightly different depending on the configuration of the NMS equipment. However, in the present invention, as an embodiment, the value of the maximum association pool is '5' and the value of the safety pin. '1' is set.

Next, it is determined whether a command is authorized from an administrator (S2), and if authorized, the command is recorded in a waiting operation list of the NMS (S3).

For smooth operation and maintenance of the optical communication system, to limit the number of associations recorded in the performance list, the instruction performance level (Water Mark) is obtained as follows (S4).

Execution Level = (Maximum Association Pool)-(Safety Pin) Equation 1

The value of the maximum association pool and the value of the safety pin are the values already set in the first step.

Compare the numerical level of the association recorded in the current manager's performance list with the water level value obtained by Equation 1 above (S5), in which case, the time stamp value has the largest association That is, the oldest one used, or the association with a very low frequency of use is deleted (S6).

After the above steps (S5, S6), it is determined whether there are any commands not authorized in the NMS waiting command list among the commands authorized by the manager (S7). Repeatedly perform (S7).

All commands authorized by the manager by step S7 are recorded in the Waiting Operation List of the NMS, and are sequentially retrieved one by one from the list to be processed first from the list (S8).

Check whether there is an association recorded to confirm the existence of each other with the corresponding manager and to facilitate smooth communication. The execution list of the manager who issued the command is recorded. Search and confirm (S9).

If it is not recorded in the above step, it is determined whether the number of associations recorded in the corresponding performance list is larger or smaller than the association level of the numerical level that can be processed by the NMS (S10). In the performing list, the association having the largest value of the time stamp is deleted (S11), an association not recorded for the execution of the command is recorded and a '1' is recorded as the time stamp value, and the time stamp value of the remaining association is performed. Record all by adding one.

In this case, in the ninth step S9, when the association of the command is recorded in the execution list of the manager, the time stamp value of the association is recorded as '1', and the remaining associations are in ascending order. After reordering and recording (S13) and determining whether there are any commands that have not yet been processed in the Waiting Operation List of the NMS (S14), the feedback is repeated so that each command is repeatedly performed separately. Let's do it.

Therefore, the association management method of the optical communication system according to the present invention as described above uses an association that is not used for a long time or has a low frequency of use so that even a limited resource of the centralized management apparatus can execute a command of an administrator that needs to be applied. By deleting and recording the association that needs to be applied immediately, the command can be executed and the reliability of the operation and maintenance of the system is secured.

The present invention as described above has the effect of effectively using a limited resource in the centralized management device of the optical communication system, and recording an association that allows the command generated by the manager to be delivered to the manager smoothly.

In addition, there is an industrial use effect to improve the reliability of the optical communication system centralized management device.
