Fault diagnosis information transferring and processing method for normalization management interface of device

Abstract

The invention provides a fault diagnosis information transferring and processing method for a normalization management interface of a device. The method is applied to a network management system which consists of a network management station (NMS), and main and sub agencies operating on an optical line terminal (OLT) device. The method is characterized by comprising the following steps: detecting the type of a fault generated by the OLT device by the sub agency, and sending a message containing the type of the fault to the main agency; judging the urgency extent of the fault by the main agency, and packaging the fault message into a packet to be sent to the NMS; analyzing the packet by the NMS and processing the fault in a classified way; receiving a responding packet returned by the NMS by the main agency. By the adoption of the method, the defect that the fault management of the OLT device is not reliable is overcome, the transferring effectiveness of the message between the main and the sub agencies is improved, the cost for improving the reliable transferring of the fault notification for a network system is saved, the main agency in the OLT can be ensured to send a fault diagnosis notification to an expected destination without omissions, so that the device can be maintained and managed in time.

Description

technical field [0001] The invention belongs to the field of network management, and in particular relates to a fault diagnosis information transmission and processing method of a device normalization management interface. Background technique [0002] At present, the Simple Network Management Protocol (SNMP) is the most widely used network management protocol in the world and the de facto standard of network management, and most network management systems are based on SNMP. The SNMP network management system is mainly composed of four parts: manager, agent, management information base (Managed Information Base, MIB) and SNMP protocol, among which the communication between Manager and agent is through SNMP protocol. The SNMP network management system can complete the configuration management, performance management, and fault management functions of the managed devices. Among them, the fault management is the most important task in the network management, and the agent in th...

Problems solved by technology

At present, in most cases, Trap is used more, because the Inform mechanism will consume more network and device resources

After using the Inform mechanism, the managed device cannot immediately discard the Inform message it just sent, it needs to save the information in the system memory until the agent in the managed device receives the corresponding confirmation message, or the specified time is exceeded , it can be seen that this mechanism needs to consume a certain amount of equipment resources

At the same time, Trap will only be sent once, while Inform may be sent repeatedly several times. This repeated sending of Inform messages and receiving corresponding confirmation messages will increase the additional overhead of network traffic.
