Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] A method for constructing an industrial multi-core network provided by the present invention comprises the following steps:

[0031] 1) Preprocessing the original industrial information network based on the maximum matching algorithm;

[0032] 2) For the original graph after step 1) preprocessing, the KL trial optimization algorithm is used for region division and node aggregation;

[0033] 3) Restore and optimize the region graph in the aggregation state, and then restore it to the original graph to complete the division of the multi-core network.

[0034] Further, the step 1) specifically includes: abstracting all nodes in the network into an original graph G=(N, E), where N represents a node set, and E represents a link set. Then define Gi=(Ni,Ei) as a subset of elements in the graph G, with G i ∈G, and |Ni|i+1=(N i+1 ,E...

Abstract

The invention discloses an industrial multi-core network construction method. The method uses a multi-center aggregation deployment algorithm to logically divide the topology structure of the multi-level multi-core SDN intelligent network. Firstly, all the nodes in the network are abstracted into an original graph and reduced to a suitable scale, then the area division and node aggregation are carried out according to the attribute values ​​of each node, and finally the divided sub-graph is backtracked into the initial graph according to the topology structure, so that This achieves a large-scale network slicing grouping effect. The construction method of the industrial multi-core network provided by the present invention is simple and feasible, is convenient for engineering realization, can solve complex tasks that cannot be handled by a single agent network, improves the load capacity of the network, and better guarantees the communication quality required by the industrial Internet.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an industrial multi-core network construction method. Background technique [0002] In the industrial production process, due to its own high reliability, high security, and high accuracy requirements, real-time reliable information transmission and accurate standard data communication are the most basic and most important for industrial information networks and ordinary civilian networks. At the same time, it is also the first technical problem encountered in the integration of industry 4.0 and industrial information promoted by the country. In the process of industrialization and informatization, the communication network must solve the core technical problems of real-time and reliable transmission. [0003] Industrial control has an instinctive requirement for real-time reliability. Real-time reliable information transmission is the most basic and important feature tha...
