Problems solved by technology

However, traps before SNMPV2 do not support trap responses, that is, after the alarm device sends a trap, no matter whether the network management system receives the trap message, it is assumed that the network management system has received the trap by default.
If the network management system does not receive the message, it will inevitably cause problems such as alarm loss and alarm information out of sync.
Although the SNMPV2 version supports the response function to trap messages, there are still some problems: in the case that the network management system has not been able to reply to the trap response, the alarm device must continue to send trap messages until it receives the trap response from the network management system. This will inevitably cause an increase in network message traffic and unnecessary workload for alarm equipment

Embodiment Construction

[0063] The details will be described below in conjunction with FIGS. 1 , 2 and 3 .

[0064] When the network element registration process occurs between the alarm device (10) and the network management system (20), that is, the alarm device (10) requests connection registration (1): the network management system (20) is shut down, or the alarm device (10) is shut down, Or after the communication link between the two is disconnected and restored, a network element registration process between the alarm device (10) and the network management system (20) needs to occur.

[0065] After the network management system (20) confirms that the registration (2) is successful, the network management system (20) uses the network management protocol to obtain the current alarm list (23) of the alarm equipment (10) to the alarm equipment (10), and obtains the current alarm list (23) of the equipment. After the list, the network management system (20) compares and analyzes the alarm list of s...

Abstract

The invention discloses an alarm synchronization method in a network management system, and relates to a synchronization method of the network management system with an alarm device in the alarm status and alert messages. The method comprises the following steps that; an alarm device (10) requests for a registration (1); a network management system (20) confirms a registration (2); the network management system (20) synchronizes an alarm message (3). The alarm device (10) generates and saves an alarm (4). The alarm device (10) reports an alarm changing issue (5). The network management system (20) synchronizes the alarm message (3). The network management system (20) records a history alarm (7). The invention realizes the synchronization of the network management system with the alarm device, thereby avoiding the loss of the alarm message.

Description

technical field [0001] The invention relates to a method for alarming in a network management system, in particular to a method for synchronizing the alarm state and alarm information between the network management system and alarm equipment, and generating related historical alarms. Background technique [0002] At present, the most common management protocol in the network management system is the SNMP protocol. The method of this protocol when dealing with alarm reporting is to report the alarm in the form of trap when any alarm-related event occurs, including the time when the alarm is generated and the alarm disappears. However, traps before SNMPV2 do not support trap responses, that is, after the alarm device sends a trap, no matter whether the network management system receives the trap message, it is assumed that the network management system has received the trap by default. If the network management system does not receive the message, it will inevitably cause prob...
