Embodiment 1

[0022] The embodiment of the present invention provides an alarm suppression method, see figure 1 , figure 1 The method flow chart of alarm suppression is provided for the embodiment of the present invention, and the method includes:

[0023] 102. Form a node dependency table according to the hardware topology, where the dependency table includes: a dependency between the node and its parent node, and a dependency between the node and its child nodes;

[0024] For hardware fault detection, due to the existence of certain connections and dependencies on hardware nodes, the node detection and alarm results actually have certain internal connections. For example, figure 2 It is a schematic diagram of node dependencies, such as figure 2 As shown, a certain line processing unit (Line Process Unit, LPU) baseboard is composed of device nodes such as A, B, C, and D. For example, A is a processor, B is a memory, C is a logic processor, and D is a clock. Processor, the working stat...

Embodiment 2

[0032] An embodiment of the present invention provides an alarm suppression device, see Figure 4 , Figure 4 It is a schematic diagram of an alarm suppression device according to an embodiment of the present invention, and the device includes: an initial unit 402 , a detection unit 404 , and a suppression unit 406 .

[0033] The initial unit 402 is configured to establish a node dependency table according to the hardware topology, and the dependency table includes the dependency relationship between the node and its parent node, and the dependency relationship between the node and its subtype nodes;

[0034] When the chip initializes node registration during the hardware startup process, the initial unit forms a dependency table containing all nodes through a doubly linked list according to the actual hardware topology. The dependency table contains dependencies between all nodes, and each node has Its parent class node and its child class node can be found through the depen...

Abstract

The embodiment of the invention provides a method of alarm inhibition. The method comprises the following steps of establishing a node dependence relation table according to a hardware topological structure and detecting the fault condition of a first node; and after detecting the fault of the first node, detecting whether a parent class node of the first node is out-of-order according to the dependence relation table and inhibiting the alarm of the first node if the parent class node is out-of-order. In addition, the embodiment of the invention also provides a device of the alarm inhibition; therefore, when hardware equipment is out-of-order, the device can effectively implement the alarm inhibition and can effectively inhibit mistaken alarm so as to be beneficial to finding the source of faults for the operation and maintenance staff as soon as possible to reduce the mean repair time of a system.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method and device for alarm suppression. Background technique [0002] As users have higher and higher requirements for communication equipment bandwidth, service capacity, and system reliability, the hardware of communication equipment is becoming more and more complex. In order to improve system maintainability, detect system faults in advance and perform fault recovery or isolation in a timely manner, online fault detection is generally performed on system hardware. When a hardware device failure is detected, an alarm will be sent to the network management center to inform the operation and maintenance personnel in time. The operation and maintenance personnel will comprehensively analyze the received alarms, locate the cause of the failure and take further solutions. For this reason, for faults that may affect business operation or have ...
