An alarm was generated. In addition, the same performance monitoring function is activated for network components that have already been activated, and it has information about it. Asynchronous Transfer Mode Enables / disables performance monitoring for performance management in a high-speed information and communication network. Its purpose is to provide a method and apparatus.

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

1 is an ATM FR NMS 100, i.e., an asynchronous transmission mode frame relay network management system, in which an operator 101 configures, operates, and utilizes resources, which are all situations occurring in a network, through a screen. You can see events that occur from time to time. Alternatively, the operator 101 may view each component information through a screen for information necessary for operation in operating the asynchronous transmission mode frame relay network management system.

The asynchronous transmission mode frame relay network management system includes a connection management 205, configuration management 207, failure management 209 and performance management 210.

The connection management 205 establishes and releases a connection at the request of a user, maintains a connected state, and transmits and receives information with the Sub_NMS 120 managing the partial network. The configuration management 207 manages network resources efficiently, manages and maintains network resource status in real time, and sends and receives information to the Sub_NMS 120 in case of events related to network resources. This is a function to inform them.

And the failure management 209 monitors the events coming from outside and inside the system and take appropriate measures accordingly, the performance management 210 stores performance measurement, measurement result data collection, and result data to know the performance of the network. It is a function to handle this when the performance alarm is received.

On the other hand, each of the management objects are to manage and store their own data for the unique function, the connection management 205 stores the routing information 203 for the virtual path (VP) to select the path of each connection, and Stores routing information 204 for the virtual channel (VC). The configuration management 207 stores and manages information for storing information of all network resources in the virtual path (VP) and virtual channel (VC) layers, and the failure management 209 stores and manages information of all events. do.

FIG. 2 is a functional block diagram showing a performance monitoring apparatus applied to the present invention and another apparatus closely related thereto, and is divided into several blocks for performance monitoring. The configuration is the performance management system 200, the upper layer system 201. It comprises an operator 202, another processor 203 and other lower layer system 210.

The performance management system 200 includes an operation receiving unit 204, a performance monitoring activation processing unit 205, a threshold setting processing unit 206, a performance alarm processing unit 207, a data processing unit 208, and a performance maintenance unit 209. .

In this case, the operation receiver 204 receives a performance monitoring activation operation when the upper layer system 201 or the operator 202 performs a performance monitoring activation operation on a network component or logical elements that need performance monitoring, and checks whether it is already activated. If it is still inactive, it is stored and managed in the data storage. The performance monitoring activation processing unit 205 processes the activation of each function required for the component by determining which performance monitoring function to activate the active component or the logical resource. The threshold setting processor 26 sets an appropriate value that is a reference point when a network component should have a certain reference point when a performance alarm occurs. This is set appropriately in view of the operator and the network as a whole.

When the performance alarm occurs, the performance alarm processing unit 207 propagates the performance information and the performance alarm to the relevant system and processor, informs the operator, or alerts the network resource component or the logical resource of the network. It is a place that handles performance alarms such as preventing the performance deterioration in advance or solving the cause of the performance degradation in consideration of the severity of the system.

The data processor 208 stores and manages all information data or performance alarm data related to activation of performance alarms and all data generated during performance processing. The performance alarm receiver 209 receives and manages performance alarms generated at network components and lower layers. In addition, the lower layer system 210 directly controls network components, and processes performance monitoring activation and reports the performance alarm generated from the network components to the performance monitoring processor.

3 is a method for activating performance data collection according to the present invention. At first, an upper layer or an operator issues a performance data collection activation command to a network component requiring performance monitoring. At this time, the data collection activation command is received by the operation receiver 204 and stores the corresponding data in the data storage (not shown) (S303). Then, by searching the information of the data data processing unit 208, it is determined whether the item for which the function for activating the function for the current test is currently activated (S304). In this case, if the item to be activated is determined as the result of step S304, the operator is notified of this.

If it is determined in step S304 that the item to be activated is not currently being activated, that is, if it is in an inactive state, it is determined whether the function to be activated is a function (305). In this case, if the function to be activated is determined to measure the traffic at step S305, the parameter is changed and stored according to the operation to lower the operation in the lower layer (S309), and then the corresponding processing routine (S312) is performed.

Here, the processing routine step (S312) first changes the information that activates the traffic data measurement to the related logical network component (S312-a), and selects a lower layer network management system that manages the point of the component to be actually activated. In step S317, the function is activated on the component of the sub-subnetwork.

On the other hand, if it is determined in step S305 that the function to be activated is for user parameter control (S307), the parameter is changed and stored according to the operation to lower the operation in the lower layer (S310) and then the corresponding processing routine (S313). ).

Here, the processing routine step (S313) first changes the information that the user parameter control measurement is activated to the related logical network component (S313-a), and selects a lower layer network management system that manages the point of the component to be actually activated. And (S313-b), and activates the function to the components of the lower sub-network (S318).

On the other hand, if it is determined in step S305 that the function to be activated is performance measurement (S308), the parameter is changed and stored according to the operation to lower the operation in the lower layer (S311) and then the corresponding processing routine (S314) is performed. do.

Here, the processing routine step (S314) first changes the information that the user parameter control measurement is activated to the associated logical network component (S314-a). For this purpose, operation and management dedicated to one specific point (OAM: Operation And Maintenance) Another layer that selects the lower layer network management system that manages the component point for inserting cells (S314-b), and extracts performance measurement data by extracting operation and maintenance (OAM) cells. A lower layer network management system for managing component points is selected (S314-c). In operation S320, an operation for activating this function is sent to a corresponding network component.

4 is a method of deactivating performance data collection according to the present invention. First, the upper layer or an operator issues a performance data collection deactivation command to a network component requiring performance monitoring. This command is received by the operation receiver 204 and stores data in a data storage (not shown) (S403). Then, the information of the data processing unit 208 is searched to determine whether an item for deactivating a function for a performance test is currently activated (S404). In this case, when the item to be deactivated is determined as the result of step S404, the operator is notified of this.

If it is determined in step S404 that the item to be deactivated is not currently being deactivated, that is, if it is in an active state, it is determined whether the function to be deactivated now is a function (405). At this time, if the function to be deactivated as determined in the step S405 is the traffic measurement, the parameter is changed and stored in accordance with the operation to lower the operation in the lower layer (S409) and then the corresponding processing routine (S412) is performed.

Here, step S412 first changes the information that disables the measurement of traffic data to the associated logical network component (S412-a), and selects a lower layer network management system that manages the point of the component to be actually disabled (S412-b). ), The function is deactivated in the component of the corresponding sub-network (S417).

On the other hand, if it is determined in step S405 that the function to be deactivated is for user parameter control (S407), the parameter is changed and stored according to operation for lowering the lower layer (S410) and then the corresponding processing routine (S413). Perform.

Wherein step S413 first changes the information to disable the user parameter control measurement to the associated logical network component (S413-a), and selects a lower layer network management system that manages the point of the component to be actually deactivated ( S413-b), the function is disabled in the component of the sub-subnetwork (S418).

On the other hand, if it is determined in step S405 that the function to be deactivated is performance measurement (S408) deactivation, the parameter is changed and stored according to the operation for lowering the lower layer (S411) and then the corresponding processing routine (S414) is performed. .

Here, step S414 first changes the information that the user parameter control measurement is deactivated to the associated logical network component (S414-a). To do this, the operation and maintenance (OAM) cell is first set at a specific point. Selecting a lower layer network management system that manages component points for insertion (S414-b), and extracting performance measurement data by extracting operation and maintenance (OAM) cells. Select a lower layer network management system to manage (S414-c). In operation S420, an operation for deactivating this function is sent to a corresponding network component.

FIG. 5 relates to a method for changing a performance threshold of a network component according to the present invention. First, an operation for changing a performance critical dimension is performed at a higher layer or by an operator to a network component that requires a performance test. When the operation is received (S502), first, data is stored in the data storage unit (S503), and the information of the data processing unit 208 is retrieved and the threshold dimension of the performance item to be changed now is compared with the existing threshold dimension. It is determined whether the same value (S504).

At this time, if the threshold value of the performance item to be changed and the existing threshold value is the same value as the result determined in step S504, the operator is not further processed and notified.

As a result of the determination in step S504, when the threshold value of the performance item to be changed and the existing threshold value are not the same, it is determined what kind of performance threshold to change now (S505). If it is determined in step S505 that the performance threshold value to be changed is an item for traffic (S509), change the data of the threshold value to be changed (S509), and find a Sub-NMS managing the component to modify the threshold value (S512). Instructs to change the performance threshold of (S516).

On the other hand, if the performance threshold value to be changed as a result of the determination in step S505 is a user parameter (S507, S510) to change the data of the threshold value to be changed (S507, S510) and finds the Sub-NMS managing the component to modify the threshold value (S513) . In addition, it is indicated to change the performance threshold of the component (S517).

In addition, if it is determined in step S505 that the performance threshold to be changed is to measure the performance data, the data of the threshold value to be changed is changed (S508, S511) and the performance data is found to find a sub-NMS that manages the component to modify the threshold. The sub-NMS that manages to evict, i.e., terminates the OAM cell, is found and instructed to change the threshold of the corresponding component (S514 and S518).

6 is a transaction guaranteed performance alarm activation and threshold change operation, the performance monitoring processor first activates the performance monitoring function for the performance check on the network components from the upper layer system 201 or the operator 202 and changes the critical dimension. Receive an operation for (S603). Then, prior to processing the operation received in step S603, data for processing is combined with the received operation information (S604) and stored in the corresponding storage (SS05). In addition, after step S603, a routine for processing each operation is determined (S606). If a processing routine is determined in step S606, information on the associated network component is changed (S607). In this case, when the information change of the component is processed in step S607, the information is stored in the corresponding storage, and prepared for storing the changed information in the storage (S609).

On the other hand, in order to activate the specific point related to the relevant point to find a process for activating the function for this point (S608), at this time prepares to store all the information and the changed information generated in step S608 in the storage (S611) ). The lower layer network management system that manages this point is sent to send the operation.

Here, when the operation of the lower layer network management system is examined, it first notifies the performance client whether the performance monitoring activation function is successful in the corresponding component (aa). The performance monitoring client then checks whether the processing result has been properly processed in the lower layer network management system or if the processing failed due to an abnormal operation (bb). At this time, if the processing of the inspection result is successful, the storage unit stores the data ready for storage (cc). If the test was unsuccessful, the DD command is to destroy all information prepared for storage in the repository (dd).

As described in detail above, the present invention activates and deactivates a performance monitoring function for performance checking on network components required in a network management system of an asynchronous transmission mode ultra-high speed communication network, which is hierarchically configured in consideration of network management ease and expansion. The scheme and the scheme for changing each performance threshold are described. First, if a command issued from the upper layer is verified and the same command is issued, the operation is immediately terminated without propagating the operation to the lower layer, thereby shortening the time for operation processing, and making the process of receiving and processing any operation more clearly. The operation of the network is improved to the operator who operates the network by preventing the operation of the operation being obscured in the middle to maintain the consistency of information.
