s2, analyzing the standard alarm, extracting and storing alarm data;
s3, setting an alarm shielding table, an alarm category table and an alarm level table;
and S4, judging whether the alarm accords with the requirement of the alarm shielding table according to the alarm data, the alarm category table and the alarm level table, and reporting the alarm which accords with the requirement.
Preferably, when an alarm of a certain type of equipment is received, the corresponding relation table is searched, a standard alarm corresponding to the alarm of the equipment is found, and then the next step of processing is performed.
Preferably, the alarm shielding table is used for recording the alarm ID and the corresponding alarm shielding manner of each alarm in the SDN controller system and the network management system. Each system filters the alarm by using the alarm shielding table of the system, and the alarm conforming to the filter is sent to the upper-layer system.
The alarm category table is used for recording alarm IDs and corresponding alarm types of the alarms in the SDN controller system and the network management system respectively. For example, x.733 contains 4 kinds of alarms "communication alarm, quality of service alarm, process failure alarm, environmental alarm", and the alarm category table maps the alarms to the 4 kinds of alarms. For example, in a Chinese Telecommunication (CTC) model, alarms are classified into 6 kinds of alarms of "communication alarm, quality of service alarm, process failure alarm, device alarm, environment alarm, device event", and an alarm category table maps the alarms into the 6 kinds of alarms.
The alarm level table is used for recording alarm IDs and alarm levels of all alarms in the SDN controller system and the network management system respectively. For example, 5 levels are defined in the YANG model, respectively, inderminate (level cannot be determined), minor, warning, major, critical 5 levels, and the alarm level table maps the alarm to these 5 alarms. For example, the CTC defines 4 levels "Emergency alert, Primary alert, Secondary alert, reminder alert" and the alert level table maps alerts to these 4 alerts.
Preferably, the alarm masking means includes one of an alarm level, an alarm type and an alarm source object.
Preferably, the alarm data includes an alarm type, an alarm ID, an alarm source object, and an alarm start time.
Preferably, the method further comprises the steps of: and judging whether the alarm meets the requirement of an alarm shielding table or not according to the alarm data, the alarm category table and the alarm level table, and recording alarm confirmation and alarm clearing operation made by a user in an SDN controller system or a network management system through an alarm operation table after the alarm meeting the requirement is reported.
According to the operation of each network management user, confirming or closing the alarm, if the alarm is closed, deleting the alarm in the current alarm operation table of the network management, and adding the alarm in the history alarm table of the network management. But only if the alarm source of the alarm really ends the alarm, the alarm is really deleted in the alarm storage module. Each SDN controller or traditional network management operation table is only the result of the operation of the SDN controller or traditional network management user of the alarm.
And respectively and sequentially polling the alarm shielding tables of the SDN controllers or the traditional network managers, and judging whether the alarm is sent to each SDN controller or the traditional network manager or not according to the respective alarm shielding tables.
Taking an alarm shielding table of a certain alarm system as an example, if the alarm shielding table judges whether to report an alarm according to an alarm level, judging whether the alarm conforms to the level defined in the alarm shielding table according to an alarm level table corresponding to the SDN controller or the traditional network manager, and reporting the alarm according to the conforming level; if the alarm shielding table takes the alarm source object as the filtering condition, reporting the alarm if the alarm source object meets the requirement of the alarm shielding table; if the alarm shielding table takes the alarm category as the filtering condition, if the alarm category is judged to meet the requirement of the alarm shielding table according to the alarm category table corresponding to the SDN controller or the traditional network manager, the alarm is reported; and after the judgment of the alarm shielding table of the SDN controller is finished, continuing the judgment of the alarm shielding table corresponding to the next SDN controller until the judgment of the alarm shielding tables of all the SDN controllers is finished.
Specifically, referring to fig. 2, according to the alarm data, the alarm category table and the alarm level table, determining whether the alarm meets the requirement of the alarm mask table, and reporting the alarm meeting the requirement, specifically includes the following steps:
101, judging whether alarm shielding tables of all SDN systems are judged, if yes, ending; if not, acquiring an undetermined alarm shielding table, and entering step 102;
102, judging the type of the alarm shielding table, and if the type is based on the level, entering a step 103; if yes, go to step 104; if yes, go to step 105;
103, judging whether the alarm accords with the alarm level of the alarm shielding table, if so, entering the step 106, otherwise, returning to the step 101;
104, judging whether the alarm accords with an alarm source of an alarm shielding table, if so, entering a step 106, otherwise, returning to the step 101;
105, judging whether the alarm accords with the alarm category of the alarm mask table, if so, entering a step 106, and if not, returning to the step 101;
and 106, reporting the alarm to a corresponding system.
Referring to fig. 3, an embodiment of the present invention further provides an alarm processing system for an access network, including:

However, for different SDN controllers or traditional network managers, there are an alarm operation table, an alarm classification table, an alarm level table, and an alarm mask table, which are independent of each other. The user of each SDN controller or the traditional network manager confirms or cancels the alarm without influencing the alarms of other SDN controllers or the users of the traditional network manager. For the same alarm message, the alarm processing of each SDN controller and the network manager is different.
Each SDN controller or traditional network manager has different classification tables and different alarm level tables for the same alarm, and forms respective alarm shielding tables according to respective alarm classification rules and alarm levels.
