The present invention relates to an event processing apparatus and method thereof in an asynchronous transmission mode ultrahigh speed information communication network, and more particularly, according to the general principles of the communication management network including the concept, scope and management structure of the M.3010 communication network. As part of the fault management system of the Asyncronous Transfer Mode (ATM) management system of the implemented high-speed communication network, based on real-time and importance for events (e.g., system failure, operational failure, etc.) generated during operation. The present invention relates to an event processing apparatus and method in an asynchronous transmission mode ultrahigh speed information communication network, which is configured to process with an assigned priority and processing option.

At present, research and standardization related to the operation management of communication network are being promoted centering on ITU-T and ISO as the international standardization organization, and apart from that, standardization research related to operation management of communication network and the management of integrated broadband communication Several projects are underway to develop a network management platform for the management of telecommunication networks that supports the establishment of an open service structure to build an environment and the integrated implementation of management services.

However, when managing a large communication network, the management of events (failures) occurring in the network is considered to be a very important factor. The reliability of the entire network or the efficiency of the communication network depends on the systematic and efficient processing result of the failure. In addition, the availability of communication facilities is improved, and the quality of communication services can be improved. In addition, the real-time monitoring of faults, pre-monitoring for performing preventive maintenance of faults, pre-detection, notification of events at the appropriate time of events, and maintenance of performance are supported. It takes a very important place and requires proper handling of events.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and its main object is to set the priority and processing options that are set in consideration of the effect on the entire network about an event (disturbance) occurring in an asynchronous transmission mode of a high-speed information communication network. The present invention provides an apparatus and method for processing an event in an asynchronous transmission mode ultra high speed information communication network to improve the performance and efficiency of the entire communication network.

In addition, another object of the present invention is that if an important event occurs when the operator operates the network, the processing process is changed based on the option for the processing to enable efficient event processing while considering the severity of each event. It provides an event processing device and method in the asynchronous transmission mode ultra-high speed information communication network that guarantees the convenience of event management by the operator by allowing the operator to detect high events first, thereby improving the reliability and efficiency of network management. will be.

In order to achieve the above object, the event processing apparatus in the asynchronous transmission mode ultra-high speed information communication network according to a preferred embodiment of the present invention receives all events occurring in the components of the network or another event generated by the events. A receiving unit for continuous reception management, an event information storage unit for storing and managing all information of events received from the receiving unit, an event attribute table for setting severity and priority of each event, processing options, and priority of the event And a priority queue for sequentially storing events of a processing target for each priority in a separately provided queue, and a processing unit processing based on a processing routine corresponding to each event.

In addition, the event processing method in the asynchronous transmission mode ultra-high speed information communication network according to the present invention receives an event occurring in a component of the network to check what event is occurring, and based on the result of the inspection, the event is attribute data Reading the memory and inspecting the processing options of the event, executing a processing routine corresponding to the inspection result, checking the priority of one of the attributes of the event, and storing the event in a queue according to the priority of the inspection result. Consists of steps.

If the inspection result is 'Nothing' in the inspection step of the processing option, no processing is performed, and the inspection result indicates that the inspection of the processing option performs only an event processing routine, or notifies the event processing routine + operator, and event processing. Routine + Notify operator + System notification, Event processing routine + Notify operator + System notification + Propagation of event to internal system (connection manager or resource manager) If the event is propagated, the event is saved along with event attribute information in the event storage.

In the queue storing step of the event, a priority is determined by inspecting an attribute of the generated event, and the space is queued in the free space by checking the free space in priority-down order from the queue corresponding to the priority. It is prepared by storing the event in the queue, and it is executed by judging the state of the thread (Thread) to keep the event in the queue and continuing to execute if it is stopped so that the event is stored in the appropriate queue while the thread is running.

In addition, the step of retrieving the event stored in the queue, the event retrieval step to retrieve the stored event from the queue of the highest priority to process the event, while locking the queue that does not hold the event Archiving of the event is prevented while checking the lower queue and waiting for input of the event if the event is not stored in the entire queue.

The processing of the event checks the processing option of the event taken from the queue, and performs the corresponding event processing routine if the processing option is processing of an event processing routine, and if the processing option is notified to the event processing routine + operator. In addition to executing the event processing routine, it executes a routine for notifying the operator.If the processing option is event processing routine + notify operator + external system call, the corresponding event processing routine is executed and the operator is notified and external system is called. If the processing option is event processing routine + notify operator + external system call + event propagation internally, it executes the event processing routine and calls the operator and external system and propagates the event internally. Run the routine.

According to the present invention of the above configuration, if any event is generated in the corresponding network component and received through the receiving unit is stored in the corresponding queue based on the priority and processing options, the processing unit stored in the queue By retrieving based on the priority and processing according to the processing option, it is possible to prioritize the events that need to be processed in real time, thereby improving the overall event management efficiency of the system.

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

1 is a functional block diagram of an asynchronous transmission mode (ATM) network / frame relay (FR) network management system (ATM FR-NMS) included in the high-speed information communication network to which the present invention is applied, the operator 201 through the screen Almost every situation that occurs in the network, that is, the configuration and utilization of resources, the connection / disconnection of the circuit occurs in real time, and all the failures that occur frequently, as well as the operator 201 the corresponding ATM FR -Information necessary for NMS operation is transmitted to each component through screen.

Here, according to the main function of the ATM FR-NMS, the connection management unit 205 establishes / releases a connection at the request of a user, maintains the connection state, and exchanges information with the Sub_NMS system managing the partial network. When an event related to disconnection is generated, a function of notifying a failure management unit to be described later is performed. The configuration management unit 207 manages network resources efficiently and maintains real-time management of network resource states and information with the Sub_NMS system 211. This function notifies the problem management unit when an event related to network resource occurs while exchanging the data.

In addition, in the ATM FR-NMS, the failure management unit 209 monitors an event (disorder) transmitted from the outside and the inside of a corresponding system, and performs a function of taking an appropriate action on the event according to the monitoring result, and the performance management unit. In operation 210, the performance measurement to find out the performance of the network, the collection of the measurement result data, and the storage of the result data, and when the performance alarm is received is responsible for the processing.

In addition, the objects of each of the management units 205, 207, 209, and 210 must manage and store data for unique functions assigned to them. In the case of the connection management unit 205, a virtual path is selected to select a path of each connection. Path (VP) routing table 203 and virtual channel (VC) routing table 204 is associated with, the configuration management unit 207 is a virtual path (VP) and virtual channel (VC) layer in all the network ( To manage and store information of the national network) resources, the ATM VP / VC configuration information table 206 is managed, and the failure management unit 209 stores an event storage table for storing and managing information of all failures. Is associated with.

2 is a functional block diagram of an event processing apparatus in an asynchronous transmission mode ultrahigh speed information communication network according to the present invention, the event processing apparatus receiving an event in association with an external system / other processor 301 and receiving a result of the event. In exchange, they interact to maintain consistent information.

In the event processing apparatus, the reception unit 302 receives the entire event generated in the corresponding network, and the received event is stored in the event information storage unit 305 to maintain the event information immediately after the reception. The event attribute table 307 stores the severity of the event, the priority of the event, and the processing options of the event.

Here, in the present invention, considering the fact that it takes a considerable time to take information from the event attribute table 307 for every event, the same event attribute information is stored in the memory 309 to shorten the processing time of the event. . In addition, since the attribute of an event is important information essential at the time of processing of the event, it is desirable to store the information twice.

Then, the events are classified based on the priority and stored in each queue 303 according to the priority, and the priority can be defined as N according to the priority of the event. For convenience, we will assume four.

In addition, the processing unit 304 is classified according to the priority of the event, take the event from the stored priority queue and process the event according to each event processing routine 308, and in some cases the external system / other processor 301 You can call or maintain the event processing status to complete the event processing.

3 shows an example of allocating an event attribute of severity, priority, and processing option for each event.

4 is a flowchart illustrating a case where an operator changes an attribute of an event in an event processing apparatus in an asynchronous transmission mode ultrahigh speed information communication network according to the present invention.

The operator 310 may search for the property of the event in the operator system. The operator first checks the property of the event from the event attribute processing change module 3-1 of the receiver 302 to the system memory. In order to access, the memory processing module 3-2 processes (3-3) the specific event number and brings the event attribute information in the memory to the operator.

Then, when the operator checks the property of the event and wants to change the property of the event, the operator transmits a command to the event property processing change module as the changed value (3-7). The event attribute processing changing module changes the event attribute in the memory by the memory processing module. The memory notifies the event attribute processing change module of the response through the memory processing module.

If the response of the memory is not appropriate, the process is not performed any more and the status is notified to the operator. If the response of the memory is correct, the event attribute processing change module may change the table processing module to change the table having the event attribute. Event property is changed through.

The event attribute table notifies the event attribute processing change module of the response through the table processing module, and informs the operator of the status when normal processing is performed. If the response is not appropriate, the event attribute table restores the event attribute data that has already been changed to memory, and then informs the operator of the failure of the event attribute change in the event attribute table.

5 is a flowchart related to the priority and processing options in the receiving unit. When receiving an event from the N event receiving module consisting of the first it is to check what event occurs (4-1), (4-2). Then, based on the inspection result, attribute data of the event is taken from the memory and the processing option for the event is examined (4-3). If the check of the processing option is 'Nothing', processing for the event is terminated without performing any processing (4-4) and (405).

If the processing option checks only the event processing routine, or event processing routine + Notify operator, Event processing routine + Notify operator + System notification, Event processing routine + Notify operator + System notification + Internal system (Connection manager Alternatively, if the event is propagated to the resource manager, the event is stored along with the event attribute information in the event storage unit (4-6) and (4-7).

Next, the priority of one of the attributes of the event is checked (4-8), and the event is stored in a queue according to the priority of the check result (4-9).

6 is a flow chart illustrating a procedure for queuing an event based on priority. The event is examined for its attributes and its priority is checked (5-1). If the priority is 1, priority queue 1 is checked to see if there is free space in queue 1 (5-2).

In 5-3, the storage of the event is prepared according to the inspection result. If there is a space in the queue 1, the storage is prepared in the queue 1 space. It checks to see if there is space, and if there is room in queue 2, it is ready to keep it in priority queue 2, even if priority is 1. If there is no space in priority queue 2, it is determined whether there is space in priority queue 3, and if there is space in queue 3, it is prepared for storage in queue 3. If there is no space in queue 3, it is checked whether there is space in priority queue 4. If there is no space in queue 4, the operator is informed that there is no space in all queues (5-4). If there is space in queue 4, the queue is ready for storage.

If the priority of the event is 2, the priority queue 2 is first checked to see if there is space in the queue 2, and if there is space in the priority queue 2, the storage of the queue 2 is prepared. If there is no space in priority queue 2, it determines whether there is space in priority queue 3, and if there is space in queue 3, it prepares for storage in queue 3. If there is no space in queue 3, it checks whether there is space in priority queue 4. Thus, if there is no space in queue 4, the operator is informed that there is no space in all queues, while if there is space in queue 4, it is kept in queue 4.

If the priority is 3, it determines whether there is space in priority queue 3, and if there is space in queue 3, it prepares to keep it in queue 3. If there is no space in queue 3, it checks whether there is space in priority queue 4, If there is space in the queue, it is kept in queue 4. If there is no space in queue 4, the operator is terminated by notifying the operator that there is no space in all queues.

If you want to keep any events on queue 1, queue 2, or queue 3, first determine whether the thread is stopped (5-5), and if the thread is stopped, continue executing the thread again ( 5-6) causes the thread to run as soon as the event is entered, storing the event in the appropriate queue, and if the thread is in a running state, the event is stored in the appropriate queue (5-7).

7 is a flowchart illustrating an operation of fetching an event from a queue. Referring to the figure, first check queue 1 in 6-1 to 6-8 to check whether the queue 1 is empty, and if the result is not empty, bring up the fault stored in the queue 1 and process the event. On the other hand, if queue 1 is empty, lock queue 1 and check queue 2. Here, the reason for locking the queue is to prevent an event from being stored in the queue 1 when the queue 2 is checked.

If the queue 2 is not empty, the event is retrieved from the queue 2 and the queue 1 is unlocked. If the queue 2 is empty, the queue 3 is checked. At this time, the cue 1 and the cue 2 are locked.

If the queue 3 is not empty, the event is retrieved from the queue 3, the queue 1 and the queue 2 are unlocked, and the event is processed. If the cue 3 is empty, the cue 4 is checked, and both the cue 1, the cue 2, and the cue 3 are locked. If the queue 4 is not empty, the event is taken from the queue 4 and the locks of the queue 1, the queue 2, and the queue 3 are released. If the queue 4 is empty, it is determined that there is no event to process and the thread is suspended to wait for an event to come in.

8 is a flowchart illustrating a process of processing an unprocessed event by a failure of an event processing apparatus according to the present invention. If the processing option of the event taken from the queue is examined and the processing option is processing the event processing routine, the corresponding event processing routine is performed (7-1 to 7-4).

If the processing option is to notify the event processing routine + operator, it executes the event processing routine and executes a routine to notify the operator (7-3, 7-5).

On the other hand, if the processing option is the event processing routine + notification to the operator + external system call, the corresponding event processing routine is executed while executing the routine for notifying the operator and calling the external system (7-3, 7-6). ).

If the processing option is event processing routine + notification to the operator + external system call + event propagation internally, the event processing routine is executed to notify the operator and call an external system and execute a routine to propagate the event internally. (7-7)

As described above, according to the present invention, among the events generated in the asynchronous transmission mode network management system of the hi-speed communication network hierarchically divided in consideration of the ease and scalability of the network management, the event to be processed in real time is higher than other events. Stored in a high queue for faster processing, and differentiating processing options by distinguishing processing options according to the importance of the event. Management becomes possible.

In addition, when there are no events to be processed, the thread can be temporarily stopped to improve the overall efficiency of the system, and the processing options for the event can be set to differentiate the event processing and cope with the event processing effectively. When an operator changes the attributes of an event during operation, the operator can change it immediately without regard for time, thereby providing a lot of flexibility in operation.
