Embodiment Construction

[0022] Usually a network is composed of different communication devices, such as hosts, routers, switches, and bridges. Devices are connected to each other and communicate through communication protocols. Network topology maintenance is to monitor and maintain all communication devices in the network and the connections between devices.

[0023] like figure 1 In the network model shown, there are 5 hosts in this network model, represented by H1~H5, 4 routers, represented by R1~R4, and 4 subnets, represented by N1~N4.

[0024] This embodiment starts from the host H1 of the network, and finally completes the topology monitoring and maintenance of the entire network.

[0025] like figure 2 As shown in the cross-network dynamic topology maintenance method of the present invention, the steps are:

[0026] A. On the basis of the SNMP protocol, obtain the default gateway in the network model, and construct a router queue. At the same time, set the maximum router hops that can b...

Abstract

The present invention relates to a cross-network dynamic topology maintenance method, comprising: A. obtaining a default gateway router according to host routing table information in a designated network, and putting the default gateway router into a router queue; B. obtaining one of the router queues The router object, as the current router, traverses the routing table information of the current router to obtain the subnet connected to it and / or the adjacent router; C. the router obtained in step B is judged and processed; D. the router in the queue Execute steps B and C for all router objects; E. After traversing the router objects in the router queue, obtain the topology information of routers and subnets in the network. The invention can monitor the network topological structure in real time, effectively reduce the network load, and the running speed of the maintenance process of the topological structure is fast. The correctness of the topology judgment of the network system is obviously improved, and the requirements of the network management for automatic monitoring and maintenance of the specified network topology are met.

Description

technical field [0001] The invention relates to computer network communication, in particular to a cross-network dynamic topology maintenance method. Background technique [0002] With the continuous development of communication and computer technology, computer network is widely used in people's life and plays an increasingly important role in the development of society. The number and types of devices in the network are gradually increasing, and the network scale is getting larger and larger, which makes network management more and more complicated. As the basis of network management, the dynamic topology maintenance method can not only discover the network topology, but also provide support for network fault management, performance management, and configuration management. The dynamic topology maintenance method can dynamically and comprehensively display the operation status of the management network, and the administrator can monitor and maintain the designated network...
