Network management system and method of guaranteeing normal communication

Abstract

The invention discloses a network management system and a method for ensuring the normal communication thereof. A backup network management Proxy is added. Under normal conditions, the backup network management Proxy monitors in real-time the state of a main network management Proxy; when detecting the main network management Proxy is invalid, the backup network management Proxy automatically is switched to the main network management Proxy and promptly notifies a network management station (NMS) and resets a destination address of a simple network management protocol agent (SNMP Agent), to allow the communication between the NMS and each SNMP Agent via a new network management Proxy. Therefore, the invention can detect the invalidity of the network management Proxy in time and automatically switch the network management Proxy, so as to rapidly recover the normal communication function of the network management system and thus to improve the safety and reliability of the network management system communication.

Description

technical field [0001] The invention relates to network management technology, in particular to a network management system based on network management Proxy backup and a method for ensuring its normal communication. Background technique [0002] With the rapid development of the network, almost all network communication devices have the network management function of the Simple Network Management Protocol (SNMP, Simple Network Management Protocol). The traditional SNMP network management system consists of a network management workstation (NMS, Network Management Station) It is composed of a network management agent (SNMP Agent) running on the managed network element device, and the SNMP Agent communicates with the NMS through the standard SNMP protocol. [0003] In order to solve problems such as inter-private network and NMS centralized management, the method of deploying network management Proxy is widely used in the existing SNMP network management system. Specifically...

AI Technical Summary

Problems solved by technology

[0005] On the one hand, the network management proxy becomes the hub of communication between the NMS and each SNMP Agent. Once the network management proxy fails and stops working, the entire network management system will be paralyzed, and the NMS will not be able to obtain the network element information collected by each SNMP Agent.

[0006] On the other hand, the network management proxy cannot be automatically restored after failure, which leads to the failure of the entire network management system to automatically restore normal functions
