Technical field

This document relates to, but is not limited to, the field of optical communications, and relates to an optical port state determination method and apparatus, and an optical communication system.

Background technique

The optical module and the optical fiber will gradually age during the working process. In many cases, the optical power failure is a slow-changing process, that is, it gradually deteriorates, and when it reaches the critical point, it causes a service failure. Due to the characteristics of the optical port, the operator pays close attention to the optical power abnormality of the network device. Once the optical port of the abnormal optical power is found, it needs to be processed in time to avoid the network engineering fault. The operator requires the network management system to The optical port that performs the service on the network performs optical power anomaly analysis, provides optical power analysis results, and collects optical ports with abnormal optical power.

In the related art, the method for determining the optical power degradation by the network management system is: the network management system first sets the performance threshold of the optical power of the optical port of the network element, and then compares the optical power performance value with the performance threshold to calculate whether the optical power state is normal. In this mode, the performance thresholds of the NE optical ports need to be set one by one. The maintenance cost is high and the efficiency is slow. For the optical modules of different manufacturers, the performance thresholds are different due to different parameter characteristics, which makes the network operation and maintenance difficult.

In the packet transmission network management system, the client first sets a specified time interval for querying historical performance data, and a positive deviation value and a negative deviation value for calculating the optical power state.

Step S302: The client triggers the judgment process according to the batch;

The client divides the network elements in the managed network into multiple batches in a fixed number of batches; sends a request to the server to query the status of the optical port of the NE.

Step S303: The server determines the status of each optical port.

After receiving the query request, the server queries the optical power performance data of the latest granularity of the optical port of the optical network as the current optical power performance value. When the query is specified from the network management database, it belongs to the specified time. The historical optical power performance data in the interval is calculated as the average optical power performance value of the optical port in the specified time interval.

The server determines the status of the optical port according to the current optical power performance value, positive deviation value, negative deviation value, and average optical power performance value. The status of the optical port can be determined according to the following formula:

Step S305: The client displays each optical port status according to the setting.

After processing the optical power degradation status query request of all network elements, the network management client calculates the paging index number according to the total number of data and the number of pages of the report; according to the currently selected display state (display all, display only degradation, display only Normally, the first batch of data is obtained from the in-memory database according to the index number; for example, only the degraded state is displayed, then the optical port data whose optical power state is degraded is obtained from the in-memory database; only the normal state is displayed, then the in-memory database is obtained. Obtain optical port data with normal optical power status; display all states, then obtain data from the in-memory database without adding filtering conditions.

The client displays the obtained data in the optical power status information report; for the optical port in the normal state, the data is displayed in green; for the optical port in the degraded state, the data is displayed in red. When viewing data by means of page flipping, the client will obtain the corresponding data from the in-memory database according to the index number corresponding to the number of report pages, and display it in the same way in the report. If you switch again When the status is displayed, the client will re-query the optical port data of the corresponding status from the in-memory database and display it in the report.
