Problems solved by technology

It can be seen that compared with the first technical solution, the use of this technical solution can reduce the probability of alarm oscillation to a certain extent, but it greatly reduces the sensitivity of network management equipment to the status confirmation of network elements.
At the same time, when a network element suffers DoS attack or is in a state of severe overload, it is actually in a state of near paralysis, and cannot meet the normal requirements of service transmission and bearing, but the network element may still occasionally poll Therefore, the network management device still judges the status of the network elemen...

Embodiment 1

[0030] FIG. 1 is a schematic flow diagram of a network element state monitoring method in this embodiment. As shown in the figure, the method in this embodiment includes:

[0031] Step 101: Initialize.

[0032] After the network element is started, the corresponding information of the network element can be initialized in the network management layer, including initializing the credibility value of the network element, the status of the network element, and the preset maximum threshold of the credibility value and the minimum threshold of the credibility value , an adjustment parameter for adjusting the reliability value, and the like. In this example, we use the following initialization methods:

[0033] Firstly, the minimum threshold of the reliability value of the network element, the maximum threshold of the reliability value of the network element, and the adjustment parameters for adjusting the reliability value of the network element are preset. Corresponding settings...

Embodiment 2

[0074] FIG. 4 is a schematic structural diagram of the network management device provided in this embodiment. As shown in the figure, the network device includes:

[0075] The request sending unit 401 is configured to send a status detection request to a network element. If SNMP, which is currently widely used, is used, the status detection request is an SNMP request.

[0076] The response receiving unit 402 is configured to receive the status detection response of the network element, corresponding to the status detection request sent by the request sending unit 401, if the request is an SNMP request, then the response is: SNMP response.

[0077] The storage unit 403 is configured to record the information of the network element, and the information may include: the current moment of the network element's credibility value, the current state of the network element's current moment, the preset highest threshold of the credibility value, the lowest credibility value A threshol...

Abstract

The invention relates ton one network element status monitor method and its management device, which comprises the following steps: according to the element status to test relative received results; determining network current time credulity value; the credulity values is as: label for network in normal probability value; if the network element original status is normal, and the current value is less than or equal to the minimum gate then judging the current element status from normal to abnormal one.

Description

technical field [0001] The invention relates to the communication field, in particular to a network element state monitoring method and network management equipment. Background technique [0002] The Simple Network Management Protocol (SNMP for short) is a set of network management protocols defined by the Internet Engineering Task Force (IETF for short). Using SNMP, a management workstation can remotely manage all network devices that support the SNMP protocol, including monitoring network status and receiving network event warnings. Although SNMP was originally oriented to IP-based network management, it has also been successfully used in telecom network management as an industry standard. [0003] Because SNMP uses the User Datagram Protocol (UDP for short) at the transport protocol layer to perform connectionless operations, and due to the inherent characteristics of UDP, SNMP cannot provide guarantees for transmission quality. As a result, when the network is congeste...
