Description

Network Management System Process Management and Monitoring Method for Multiple Users

The present invention relates to a process management and monitoring method for a network management system (NMS) multi-user, in particular, based on an asynchronous transfer mode (ATM) exchange. The present invention relates to a method for efficiently operating a network management system for managing a network of a switching system.

In general, a conventional network management system has been developed for a single user and has been implemented to operate only one network management system program in a system.

Such a conventional network management system has a structure in which each module is executed after a necessary background process is driven by itself while a network management system program is driven.

That is, it has a structure for driving processes for exchanging data with an exchanger system (hereinafter, referred to as a network element (NE)) after driving its own process for operating the network management system.

Therefore, when two or more programs are executed in one system, processes of the same function and content are driven in multiple times.

This greatly degrades the overall performance of the network management system and can lead to program downtime or errors in the transmission and reception of network elements due to inconsistencies when the same process is operated using different parameters. I have a problem.

In addition, it does not meet the basic intent to be able to distinguish and operate the functional rights of various users registered in the network management system.

Therefore, the present invention was devised to solve the above problems, and by using a daemon process called a session manager separate from the network management system program, a plurality of users can be connected to one workstation. A network management system capable of running two programs is provided to provide a process management and monitoring method for multiple users.

Another object of the present invention is to provide a process management and monitoring method for a multi-user network management system having a watchdog function that periodically checks and restarts a process status as well as driving a process.

It is still another object of the present invention to provide a process management and monitoring method for a multi-user network management system that kills an existing process and runs a process applying a new parameter when the use environment is changed.

The above and other objects and novel features of the present invention will become more apparent from the following detailed description of the invention and the accompanying drawings.

1 is a flowchart illustrating a process management and monitoring method for a multi-user network management system according to the present invention.

A preferred embodiment of the process management and monitoring method for a network management system multi-user according to the present invention, which was devised to achieve the above object, comprises the steps of: installing a network management system workstation, before running the network management system program; Starting a daemon process called a session manager, reading each parameter necessary to run the daemon process from a database, starting each process, storing a process identifier and a status flag in a common memory while invoking the process; Checking the state of the process based on the contents of the common memory.

In the present embodiment, it is preferable that the session manager assigns the authority to the super user so that the authority can be changed to suit the function of each process in consideration of the authority of each user of the network management system.

In the present invention, unlike the prior art, since only one process is to be run on a workstation regardless of a user, a daemon process called a session manager is used to implement a function of managing and monitoring a process for multiple users.

In the present invention, when all installations of the network management system workstation are completed, the session manager is driven to run a daemon process that is driven regardless of user's authority. This enables communication with network elements (checking all traps and real-time status of network elements), so that statistical data and billing information to be managed by the network management system can be stored.

If you run the network management system program for each user authority, you can run the process that can be run according to the authority and use it for each module, and you can refer to the contents managed in the session manager.

The session manager's authority is the super user. This is to allow the authority to be changed according to the function of each process in consideration of the authority of each user of the network management system.

A total of eight processes run by the session manager are as follows. The session manager stores the process identifier (process_id) and state in shared memory.

The eight processes to be managed include an alive check process of a network element, a real state check process of a network element, a log handling process brought from the network element, and a trap handing coming from the network element. The process of storing data in a database in the process and network management system, the process of tabulating the Management Information Base (MIB), the process of periodically importing performance management module logs from network elements, and the browsing of traps. There is a process that is browsing.

If the process terminates abnormally, it may have a sensitive effect on the real status with the network element, so check the status of the process that has been started periodically every 3 seconds to reload the processes that are not running. Implement the watchdog feature.

In addition, the user can monitor the status of a process at any time, and the function of displaying the contents stored in the common memory can be displayed to show the name and status of the currently running process.

Even when the program is not running, the session manager communicates with the network element so that alarm history, billing information, and statistical information by traps can be stored in the system and monitored at desired time.

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

1 is a flowchart illustrating a process management and monitoring method for multiple users of a network management system of the present invention.

First, when all installations of the network management system workstation are completed, a daemon process called a session manager is started before the network management system program is run (10). The session manager has a function of driving, managing, and monitoring basic processes not related to user rights for a multi-user system.

Then, the parameters necessary to run this process are read from the database to drive each process (20).

Invoking the process stores the process identifier and status flags in shared memory (30, 40).

Once every three seconds, the process status is checked based on the contents of the common memory to recall a process that is not running or terminated abnormally and store new information in the common memory (50).

This periodically checks the status of the process to provide management and monitoring functions.

In a network management system operating as described above, a user having an administrator's authority among the network management system users may change a parameter for this process.

To reflect this, if a network control system has a process control module with the authority of common memory among management functions and updates the parameter in the database, it automatically connects the process identifier related to this parameter to the common memory. Find and force quit. The session manager's watchdog reinvokes the process with the new parameters.

This allows a large number of users to run the function according to their own authority, and only a user with administrator authority can operate the monitoring function for the session manager.

In the present invention described above, a super user, an administrator, and the like are omitted because they are obvious to those skilled in the art.

While the invention is susceptible to various modifications and alternative forms, the disclosure thereof has been described with reference to specific embodiments only. It is to be understood, however, that the invention is not limited to the specific forms referred to in the specification, but rather that the invention is defined by the appended claims, all modifications, equivalents, and substitutes falling within the spirit and scope of the invention. It should be understood to include.

In the present application operating as described above, the effects obtained by the representative ones of the disclosed inventions will be briefly described as follows.

In addition to the network management system program, a daemon process called session manager is used to establish a process structure for multiple users and manage / monitor functions according to privileges.

This allows multiple users to run a network management system program on a single workstation and to operate network management functions by accessing a network management system workstation from a remote location.

By setting the session manager's authority as a super user, the authority of each process can also be set, and the functions that can be changed within the program are limited to administrators, so the functional system according to the authority can be operated according to the purpose of multiple users. .

In addition, in the past, the data managed only by running the network management system program can be managed by receiving data from the network element without losing a moment by the operation of the session manager. Of course, background processes that need to be applied and operated differently according to users can be managed by the network management system program.
