Problems solved by technology
Moreover, due to the dynamic nature of the network topology, the network topology is constantly changing with the addition and withdrawal of network nodes and connections. It is very difficult and cumbersome to track and maintain the changes of the network topology manually.
Especially in a network environment with a relatively large scale and a complex structure, this method is inefficient and has a single topology

The invention provides a method for generating the network topology of an industrial system. The method comprises the following steps: acquiring each equipment in the industrial system and generating a physical topological structure of the industrial system; reading a subnet mask list of the industrial system and obtaining a plurality of different network segments according to the subnet mask list; acquiring the IP (Internet Protocol) address of each equipment, and allocating each equipment to different network segments according to the IP address; generating the network topology of the industrial system according to the physical topological structure and the network segment to which each equipment belongs. The invention further provides a corresponding system capable of automatically generating the network topology of the industrial system quickly. The topological structure can fully present the network topology information of the system.
Description
technical field [0001] The invention relates to the technical field of network topology, in particular to a method for generating a network topology of an industrial system and a system for generating a network topology of an industrial system. Background technique [0002] Today, network management has developed into an era of intelligent and visualized management. However, in many industrial systems, the traditional network management mode mainly based on manual management is still used for network management. The management and maintenance of the network are all carried out manually, and there is no graphic display for the network topology. This management mode is only suitable for a network environment with a simple structure and a small number of devices. However, the network environment of modern industrial systems is generally relatively large in scale, with various devices and complex network structures. When a network failure occurs, it is difficult to find the f...
