2 is a configuration diagram of a management information base block in a 10Gbps device delegate function for a TMN.

The configuration of the management information base block in the 10Gbps device delegate function for the TMN will be described with reference to FIG. 2.

This is a functional structure diagram of the delegate information base 35 performed in the AP 30 of the 10Gbps optical transmission maintenance system.

The delegate information base is composed of a configuration management object part 35a, a failure management object part 35b, a performance management object part 35c, and a support object part 35d.

In the configuration management object unit 35a, there are objects related to a signal that can be accommodated by the 10Gbps optical transmission device and the facilities and state control functions of the hardware constituting the same.In the problem management object unit 35b, a failure of the network and the network element Recognizes and reports and performs functions related to diagnosis and recovery, and the performance management object part 35c has an evaluation and reporting function of the performance of the network and the network elements, and the support object part 35d has configuration, failure, and performance. Consists of functional objects that support managed objects.

The 10Gbps transmission device is connected to the communication management network and needs an information base composed of the above objects to perform standardized management functions as an agent.

In particular, the performance management object part 35c maintains the performance history of 15 minutes and 1 day, which is the standard monitoring period in the synchronous transmission device, thereby enabling the performance analysis of the 10Gbps device to be used in the transmission path between stations.

The present invention devised a method of maintaining a history object while allowing a synchronous transmission device to perform a standard performance management function on a communication management network. It is possible to maintain the history for each transport channel for performance monitoring.

The 10Gbps synchronous (Synchronous Digital Hierarchy, hereinafter referred to as SDH) optical transmission system has been developed in Korea as a part of HAN / B-ISDN project, a national project by the Korea Electronics and Telecommunications Research Institute since 1993.

When the transmission system acts as a proxy of the communication management network, the management information base is a repository of management objects that provide status for the management function of the communication management network while maintaining all the information of the device in a standardized form.

In the conventional technology, the management information base is operated as a passive information store between the administrator and the actual device, but in order to keep the state of the device as inconsistent as possible, the objects carrying out each management function in the delegate have exactly the necessary information. There was a problem that must be kept without loss.

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

Since the history object is maintained for every transport channel, history objects included in the performance object of each channel exist and are created for a period designated by the administrator.

In addition, the history of multiple sections, relay sections and multiple adaptation sections, which are the scope of performance measurement, is maintained separately.

According to the present invention, as the relative unique names of the history objects corresponding to the performance objects of 15 minutes and 1 day are sequentially configured, the administrator may delete the history data or change the maintenance period. A new history is generated or the history period is changed. When the history object is deleted by the administrator, the administrator creates and notifies the object.

3A to 3B are flowcharts of performance monitoring object function in the management information base block.

A process of performing the performance monitoring object function in the management information base block will be described with reference to FIGS. 3A to 3B.

Performance monitoring in the synchronous transmitter is standardized to operate every 15 minutes and 1 day, so that performance objects can operate for two monitoring cycles.

When the operation of the 10Gbps device is started, the delegate function is performed and the initialization of the performance monitoring object such as matching with the actual resource information is performed (S1).

After the initialization of the performance monitoring object, if the M-SET service request is received from the communication management network manager or the MP, it is first checked whether the change request period is maintained (S2).

In the case of the change of the period after the history maintenance period change request inspection, the management status at that time is locked (S3) and the error is notified because the change is impossible in the locked state (S13).

After checking the lock status, after checking for 15 minutes, the minimum history retention period is 16 or more (S4). If the required history retention period is justified, the maintenance period attribute is changed (S5) and the manager is notified (S6). .

Compared with the changed history retention period (S7), if the retention period is reduced (S7), the value of the history management variable is adjusted (S8), and the history is deleted as much as the reduction of the retention period (S9) and then deleted. Notify the administrator what the history object is (S10).

In the case of one-day monitoring after the notification of deletion of the history object, it is checked whether the minimum history retention period is 1 or more (S11). If the request for the history retention period is not justified, an error is notified (S12), and a performance report is received from the MCPS. In one case (S14), first, the index for the history object is compared with the maximum value (S15).

After comparing the index for the history object with the maximum value, if the index is larger than the maximum value, the history of the end portion is all copied to the history starting from 1 (S16), and after the history of the end portion is copied, it is deleted ( After the step S17), the start of the variable for maintaining the history is reset to 1 and the end to the history keeping value (S18).

If the history object index does not exceed the maximum value after comparing the history object index with the maximum value, a new object is created (S19), a value is assigned to the history object (S20) and the object is created (S21). One end value of the variable for maintenance is increased (S22), and then the value difference between the variables for history maintenance is compared (S23).

After comparing the values of the variables for history maintenance, if the history object is longer than the maintenance period, the oldest object is deleted (S24), and the administrator is notified of the deleted object (S25). Increase the value by one (S26).

On the other hand, the performance management object is permanently executed in the delegate process. If the termination signal is received from the operating system (Operating System, hereinafter referred to as OS) (S27), execution ends.

As described above, the present invention can retain performance history data according to a standard model in a 10Gbps optical transmission system, perform a performance monitoring history inquiry function of a 10Gbps optical transmission system from a TMN manager, and maintain a history of performance monitoring data of a 10Gbps optical transmission system. The period can be changed, and the effect is that notification of generation and deletion of 15 minute and daily performance history data of the 10 Gbps device is possible.
