Network element state detecting method and network management equipment

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...

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 element as normal. Therefore, for the above situation, the network management device may need to go through multiple cycles of polling before it can discover the fault status of the network element. This technology On the one hand, the solution reduces the sensitivity of network management equipment to the status confirmation of network elements.

On the other hand, and more seriously, for the network management equipment, in the case of such a misjudgment, the detected state is a normal network element, which is actually probably already in an unavailable state. This kind of misjudgment may have a great impact on network transmission and management
