Description

Detection method, device and network management device for long-lighting optical network unit

Technical field

The present invention relates to the field of communications, and in particular to a method, a device, and a network management device for detecting a long optical network unit (OPU).

Background technique

Passive Optical Network (PON) technology is currently the preferred and mainstream technology in the field of optical access networks. It has obvious access rate, bandwidth efficiency and split ratio, full service carrying capacity and security. Advantage. PON technology is also divided into Ethernet Passive Optical Network (EPON) and Gigabit Passive Optical Network (GPON), and EPON technology is the last mile of IEEE802.3 Ethernet ( The Ethernet for the First Mile (EFM) working group is standardized; the GPON technology is proposed and standardized by the International Telecommunication Union Telecommunication Standardization Group (ITU-T).

A typical PON system consists of an optical line terminal (OLT), a user-side ONU, and an optical distribution network (ODN). The most common service scenario is fiber-to-the-home (Fiber To). The Home, referred to as FTTH, deploys an ONU for each home to provide data and voice services for a single home. The ONU connects to an OLT PON port of the OLT through the ODN, and each OLT PON port on the office side passes the ODN simultaneously. Connect dozens of home users ONUs.

In the FTTH operation and maintenance management process, operators often have such a situation. OCU users often report that the ONUs in the home are often dropped without any reason, and the operator's fault handling department is difficult to eliminate such faults, because the causes of the faults are many. It is not caused by the problem of the faulty ONU itself, but by the long-lighting of some other ONU under the same OLT PON port. This long-lighting ONU is a faulty ONU, which does not affect its own service but affects the normality of other ONUs. Used, such an ONU is known in the industry as a long-lit rogue ONU.

The presence of a rogue ONU will cause other ONUs to drop frequently, which seriously affects the normal operation of other ONUs. It is especially important for the O&M operation and maintenance department to quickly locate and find the rogue ONU under the OLT PON port.

However, it is not easy to locate the rogue ONU. At present, the more common method is to monitor by the OLT, find the rogue ONU through the algorithm, and then report the alarm to the network management system to indicate which rogue ONU, but this way through practice Proof is still very flawed. The biggest shortcoming is that OLT can't reliably find all long-lit rogue ONUs. It can only find long-lit rogue ONUs with very obvious faults, while some rogue ONUs only occasionally appear abnormally long-lit. In the case, OLT is hard to find them, and there is no other way to find them, but their harm is huge. Even occasional long-lighting will cause other normal ONUs to drop the line, and this kind of failure, the operator's It is difficult for the operation and maintenance department to locate. In the long run, such rogue ONUs that are suspicious and cannot be discovered soon become more and more difficult problems in the operation and maintenance of operators.

In view of the difficulty in detecting long-lighting ONU failures in the related art, an effective solution has not yet been proposed.

A fault occurs between the OLT and the OLT port, and the alarm message indicating that the ONU is connected to the OLT is reported. The long-light ONU does not fault or report the alarm.

Therefore, in the following embodiment, when a large-scale ONU is offline or dropped on a certain OLT PON port, it can be determined that there is a long-lighting ONU, and since the long-emitting ONU does not report the alarm information, it can be considered that The ONU that reports the alarm information is a long-light ONU.

In the following embodiments, as long as the range of the ONU can be reduced, the long-lighting ONU is not necessarily completely detected. For example, if there are multiple ONUs that do not report alarm information, the embodiment of the present invention can determine the range of the ONUs that do not report the alarm information, so that the long-emitting ONUs can be further filtered from the ONUs that do not report the alarm information.

Step S402: Set a search condition for retrieving the history alarm library of the network management device.

The search conditions mainly include the range of the OLT or OLT PON port and the time period of the retrieval. For example, the OLT device of the entire network can be retrieved to discover all the suspicious long-lit rogue ONUs in a specified time period. For another example, a specific OLT PON port may be retrieved to discover all suspicious long-lighting ONUs under a specified OLT PON port within a specified time period. For another example, the status of the PON network in a specified range can be monitored in real time, and each time interval is retrieved to find a long-lighting rogue ONU in real time.

All alarm records.

The retrieved alarm records are used for analysis and eventually discover suspicious long-lit rogue ONUs.

Step S406: analyzing the alarm and obtaining a list of suspicious long-lit rogue ONUs

The retrieved alarms are sorted according to the PON port organization, and then the alarms under each PON port are analyzed one by one. And finally obtain a list of suspicious long-lighting rogue ONUs under the PON port.

The alarm analysis process for each PON port is as follows:

From the alarm information of the PON port, it is found whether there is a large number of ONU branch fiber break alarms or ONU offline alarms or ONU power failure alarms or the like in a short period of time A. If it does not exist, it indicates that the PON port has no suspicious long-emitting ONU. If this phenomenon exists, it is necessary to find out whether the following phenomenon exists: In the above A time period, whether the PON port reports the PON LOS or the backbone fiber break alarm, if it exists, it indicates that a large number of ONUs are dropped due to PON LOS. Or caused by the backbone fiber break, if this phenomenon does not exist, it is likely that it is caused by the long illuminating of a rogue ONU. According to the long-lighting ONU, other ONUs may be faulty, but they are not faulty. All ONUs that are online and have not reported ONU branch fiber break alarm or ONU offline alarm or ONU power failure alarm or similar alarm are obtained. List, the list of obtained ONUs is a list of suspicious long-lit rogue ONUs, and the real long-lit rogue ONU must be in this list.

Further, the more times a PON port has a large number of abnormal ONUs dropping in a very short period of time during a very short period of time, the more accurate the suspicious rogue ONU is found, because each abnormal situation can acquire one. Suspicious long-lit rogue ONU list, multiple anomalies, can obtain multiple suspicious long-lit rogue ONU lists, then the intersection of these multiple suspicious long-lit rogue ONU lists should be the most suspected long-lit rogue ONU list.

Further, the time-based polling method, that is, the network alarm device historical alarm library is retrieved every interval, so that the entire OLT network management equipment system environment can be continuously monitored, and once the rogue ONU long-lighting phenomenon is found in the retrieval period, Get a list of suspicious long-lit rogue ONUs in a timely manner.

In the preferred embodiment, the suspicious rogue ONU is discovered through the historical alarm library of the network management device.
