Problems solved by technology

A relatively simple implementation method is to display all the topological information of the entire network on a GIS map. However, due to the limited size of the GIS map display plane and the limited field of view of the human eye, when there are many network objects, the display effect is not good, and in Displaying a large number of objects on one map seriously affects system performance

Embodiment Construction

[0015] Embodiment of the invention

[0016] Firstly, the definition of a hierarchical network GIS map is given: including three basic objects, nodes, which represent managed network equipment, such as hosts, switches, routers, etc.; network, which represents a set of objects and the interconnection of these objects. These objects can It is a node, or it can be a network; a link, a link represents a connection between nodes or networks; in addition, there is a definition of network status.

[0017] Define 1 node:

[0018] The node is a triplet: , Where I is the identification of the node; L indicates the level of the node in the hierarchical map; S indicates the running status of the node, see Definition 9 for details.

[0019] Definition 2 network:

[0020] The network is a five-tuple: , Where I is the identifier of the network; L is the level of the network in the hierarchical map; M is the network-related GIS map, see definition 4 for details; T is the interconnection topology i...

Abstract

The organization method of hierarchical computer network GIS map includes the following steps: constituting hierarchical network structure in practical requirement; constituting relevant GIS maps foreach network in the hierarchical structure; and adding corresponding practical links to the hierarchical network GIS map for all connections in the network topology while maintaining the consistency between the practical link and upper convergent link. The hierarchical network GIS map provides hierarchical network topology and state information converging and de-converging method. The present invention provides the topological updating and state updating algorithm for hierarchical network GIS map and can maintain the topological consistency and state consistency of network GIS map. The present invention may be used widely in computerized network management system and network monitoring system.

Description

Technical field [0001] The invention relates to the technical field of combining geographic information systems (GIS) and network management systems, in particular to a method for organization and maintenance of GIS-based computer network maps, in particular to a method for organization and maintenance of hierarchical network GIS maps. Background technique [0002] Geographic Information System (GIS) is a system that combines software and hardware. It supports the collection, storage, and display of geospatial data, and associates geospatial data with related reference data, and provides information query and analysis functions. GIS has been applied in more and more fields with its intuitive and visual characteristics. The computer network management system is also a system that combines software and hardware, providing network failure management, configuration management, security management, performance management and billing management functions. In recent years, GIS has also ...
