Description

Network Management Platform and Methods Using Threads

The present invention relates to a network management platform, and in particular, an agent of a corresponding network management platform creates a thread for each manager's management operation service as well as for each manager's management operation service to dedicate a specific manager. A network management platform and method using threads.

In general, a Telecommunication Management Network (TMN) has a Manager and Agent model proposed by the Open System Interconnection (OSI) Network Management Scheme, which manages one or more management operations and provides management operations services to the agents. The agent manages the managed objects in the agent management area and performs the management operation service requested by the manager or informs the administrator of the notification authorized by the managed object.

The management operation service includes a generation management operation service, which is a generation service of a management object, a get management operation service for providing information of the management object, and a set management operation service for changing attribute values of the management object. , A delete management operation service for destroying a management object, an action management operation service for causing a management object to perform a specific operation, and the like.

As shown in FIG. 1, the existing network management platform includes an administrator 11, an agent 12, and a process 13. The agent 12 manages operations from the manager 11. Receiving a request to generate a process (13) for each management operation for the management operation request to be dedicated to the performance, the one process (13) processes all management operation services.

In this case, since the corresponding management operation service is processed sequentially, other management operation services cannot be processed while one management service is interworked with an actual resource, thereby degrading system efficiency. In addition, since each process 13 to process the management operation service must be made for each request of the management operation service, the resources of the system occupied by each process 13 increases, and communication control between the processes 13 becomes difficult. have.

In other words, in the related art, the agent creates a process for each management operation for a management operation request from an administrator, so that the agent is dedicated to performing the operation. When there are more management operation services to be processed by a single process, the agent processes sequentially. Due to the characteristics of the process, the processing of the management operation service and the response of the management operation performance are slow, and other management operation services cannot be processed at the same time. Also, as the number of management operation service requests must be created, more system resources must be allocated. Communication control was difficult.

In order to solve the problems as described above, the present invention relates to a dual parallel structure for each administrator and management operation in the network management platform, the management operation for the management operation that the agent of the network management platform is requested from the administrator Rather, by creating threads for each administrator to dedicate specific managers, it is easy to control communication between threads and process multiple management operation services in parallel without waiting for the completion of one management operation service. And to speed up the response to the management operation performance to improve the efficiency of the entire system.

Characterized in that made.

In addition, the network management method using a thread according to an embodiment of the present invention for achieving the above object is a process for creating a dedicated agent for each of the administrators independently of the request of the management operation service from the administrators; Processing the management operation service by the dedicated agent for each administrator in parallel and processing them in parallel; Performing region processing and class level filtering in an inclusion tree for requests of different management operation services from the responsible manager; Creating independent thread execution threads for managed objects that have passed the region processing and class level filtering; And handling the different management operation services by the operation execution thread for each management operation in parallel.

In the present invention, the agent is created as a multi-thread in one process so that the thread plays the role of the agent. Since the multi-threads created in one process share data with each other, it is easy to control communication between threads and manage one. It can improve the efficiency of the whole system by processing multiple managed operation services in parallel without waiting for the completion of the operation service.

Hereinafter, with reference to the accompanying drawings will be described as follows.

2 is a block diagram illustrating a network management platform using threads according to an embodiment of the present invention, and FIG. 3 is a flowchart illustrating a network management method using threads according to an embodiment of the present invention.

In the network management platform using threads according to an embodiment of the present invention, as shown in FIG. 2, the agent is divided into three parts to perform a management operation service for each administrator and for each management operation. A dedicated agent (30) for receiving a management service requested by an administrator using an agent kernel 20 and an associated number of administrators authorized by the corresponding agent kernel 20 and generating a thread of responsibility. And a plurality of operation execution threads 40 for performing actual management services.

The agent kernel 20 performs connection establishment from an administrator and initialization of internal data structures, and provides dynamic addition of classes to handle the extensibility of agents.

The dedicated agent 30 exists in the form of a thread and takes charge of one administrator to perform a management service, and when a plurality of managers request a connection, a plurality of dedicated agents 30 are managed by the agent kernel 20. It is created in the form of threads for all of them, sharing a common management information base (MIB) and data structure. In addition, the provision of management services to the manager in charge includes filter grammar checking, scoping, class level filtering, and blank responses to connection responses. In addition, performing a role for the corresponding thread management generates the execution thread 40 for each managed object that has passed the area processing and class level filtering in the include tree, and executes a function of the managed object to generate a termination and an error. Let's do it.

The operation execution thread 40 is a thread generated in parallel for different management operation services by the dedicated agent 30, and independently executes a management operation service requested by an administrator for the selected management object. . In addition, the result of performing the management operation service is independently notified to the administrator and notifies the end of the management operation performance to the dedicated agent 30 who manages itself, and finally the dedicated to notify the end of the management operation service Let the agent 30 send a blank response to the manager.

A process of performing a management operation service of a network management platform using threads according to an embodiment of the present invention will be briefly described with reference to the flowchart of FIG. 3 as follows.

First, when managers request management operation services, the agent kernel 20 receives the management operation service requests of the corresponding administrators (step S1) and generates an independent agent 30 independently for each manager (step S2). ).

Then, the respective dedicated dedicated agents 30 respectively process the management operation services for each administrator in parallel (step S3), and check whether there is a request for a different management operation service from each responsible manager (step S4). The area processing and class level filtering are performed in the inclusion tree for the identified different management operation services (step S5).

Accordingly, the operation execution thread 40 is independently generated for the management objects that have passed the region processing and the class level filtering (step S6), and each of the operation execution threads 40 is generated for each management operation. Each management operation service is performed in parallel (step S7).

Referring to FIG. 2 in more detail with respect to performing the above operation, in the agent initialization process, the agent kernel 20 first initializes the inside of the agent by its structure constructor, and the GDMO. The compiler reads the external data structures stored in auxiliary storage, initializes internal data structures such as creating internal data structures, setting pointers between internal data structures, creates the scheduler and monitor in the form of threads, and creates agents from external files. It reads basic managed object data that will be created at the time of creation and registers the created managed object instance in the inclusion tree while reading persistence managed object information from disk or database to create persistent managed object. Register it in the include tree, Registers the functions required for the monitor or scheduler.

The agent kernel 20 checks whether there is an association request from the administrator, sets up the association according to the association request of the administrator, and generates the dedicated agent 30 to transmit the association number. In addition, the agent kernel 20 repeatedly performs the above-described operations while waiting for a new association request from the administrator.

In addition, the agent kernel 20 performs a role for dynamic addition of a management object class, and ensures continuity of management by adding a new management object class even while providing a management operation service.

In other words, when an agent developer creates a new managed object, compiles it into a library, converts the library with an ID in the form of a shared object file, and authorizes the dynamic addition attempt to the agent, the agent In the kernel 20, all manager requests are stored in a queue and held, and after executing a function registered in the monitor during the agent initialization, the internal data structure is initialized and a management object class is registered. do. Therefore, the agent developer is notified whether the registration is successful, and the agent is returned to the normal agent state and the management request stored in the corresponding queue is performed.

At this time, if the added class is an extended class (Extended Class or Actual Class) of the existing class, the agent kernel 20 adds the management object class information of the extended class and the existing allomorph class You must update the data of management object class information in. That is, change the instantiation function of the existing homogeneous class to null and change the variable of managed object class information :: check homogeneous to '1'. Then, referring to an allomorph table, managed object class information:: check The location of the managed object class information of the extension class is stored in a variable of the homogeneous type.

Accordingly, the dedicated agent 30 is a thread generated by the agent kernel 20 and has an association with one manager and is responsible for a management request received from the manager. In case of receiving the error, the domain is processed in the include tree after checking whether the filter grammar is correct.

In class processing, the class level filtering is performed to reduce the number of selected management objects. In addition, it is possible to reduce the number of managed objects to be filtered, to reduce the overall system load and to shorten the overall response time.

Accordingly, the operation execution thread 40 is generated for the managed objects that have passed the region processing and the class level filtering. If there is another connection request of the manager, the dedicated agent 30 is newly generated and the management operation service request from the manager is processed through the generated dedicated agent 30 in the same manner as described above.

In addition, when the dedicated agent 30 receives the request for generating the homogeneous heterogeneous class, the variable of the management object class information :: check homogeneous heterogeneity is checked to determine whether the corresponding class is homogeneous. If the administrator has specified an extension class, the instance creation function of the class is called and the extension class is not specified.

Finally, the operation execution thread 40 independently creates management objects selected by the region processing and class level filtering in the inclusion tree and provides respective management operation services. Information necessary for execution is obtained by using an internal data structure, and a plurality of operation execution threads 40 simultaneously provide management operation services for selected management objects, thereby speeding up processing response.

The operation execution thread 40 independently notifies the administrator of the execution result after performing the management operation service, and notifies the dedicated agent 30 of the termination of the management operation service so that the dedicated agent 30 finally receives the result. Sends a blank response to the administrator indicating the end of the service.

As described above, the management operation requested by the administrator according to the present invention generates a thread of a dedicated agent for each administrator to be responsible for a specific administrator, and the dedicated agent generates an execution thread for each management operation to perform a management operation. By allowing parallel processing, it is easy to control communication between threads and can process several management operation services in parallel without waiting for the completion of one management operation service. Faster to improve the efficiency of the whole system.
