Problems solved by technology

But once the network is blocked, the management information of the lower-level nodes cannot be obtained and reported normally, and the system will lose the ability to monitor the lower-level network, especially in the IP network of hierarchical tree networking mode, this shortcoming is more prominent

Embodiment

[0025] Such as figure 1 As shown, the IP network adopts a tree networking mode, and routers between nodes are connected through remote links. The entire network is divided into three levels of management centers, each of which is responsible for managing and maintaining the network, equipment and services of the node. The first-level management center is equipped with a network management server, which is responsible for monitoring and managing the equipment and network status of the entire network. The management centers at all levels obtain management information from the network management server of the first-level management center by connecting network management terminals, and check the network operation status within the jurisdiction of their respective management centers.

[0026] When the link is working normally, the network management server deployed in the first-level management center can detect and manage each node in the whole network, and collect and aggregate...

Abstract

The invention discloses an emergency control method and a system thereof for a hierarchical network management system, belonging to the technical field of information network management. The method comprise the following steps of: monitoring link state, specifically, performing break-make detection on a link of an upper-level network node by a virtual network management server; redirecting information, specifically, redirecting network management information of local and lower-level network devices to the virtual network management server when detecting that an upper-level link is blocked; recovering information redirection, specifically, redirecting the network management information of the local and lower-level network devices to a network management server while the virtual network management server detects that the upper-level link is recovered; and reporting the management information, specifically, uploading each piece of management information data generated during the period of link blocking to the network management server by the virtual network management server. The method and the system need no additional hardware device, and can deploy and carry out the emergency control at the nodes of each level in the whole network by simply setting a browser of a network management terminal, so that the implementation is simple.

Description

technical field [0001] The invention relates to an emergency control method and system of a hierarchical network management system, belonging to the technical field of information network management. Background technique [0002] Large-scale private IP WAN networking usually adopts a hierarchical tree networking method and is managed by a hierarchical management system. A network with a three-level management system divides the entire network into three-level management domains from top to bottom during networking. The routers in the first-level management domain connect to the routers in the second-level management domain, and the routers in the second-level management domain connect to the routers in the third-level management domain. The first-, second-, and third-level management centers of the entire network are responsible for direct maintenance and management of the networks of their respective management domains, and the upper-level management centers indirectly man...
