Abstract

The invention relates to a functional SDN northbound interface system and an implementation method suitable for heterogeneous industrial networks, belonging to the technical field of industrial networks. On the basis of fully considering the business characteristics of the industrial network, the present invention concentrates and abstracts the network resources of the industrial wireless network into a virtual resource pool, and performs unified arrangement and integrated management of the virtualized resources of the industrial wireless network and the industrial backhaul network through the resource arrangement unit , so as to provide a basis for the function opening of the northbound interface. The functional SDN northbound interface system designed by the present invention can flexibly provide two levels of functional northbound interfaces, the industrial wireless network functional interface and the integrated management interface, to the upper-layer network managers. At the same time, when accessing a new network, the system only needs to Modifications at the software level are made with high scalability.

Description

technical field [0001] The invention belongs to the technical field of industrial networks, and relates to a functional SDN northbound interface system suitable for heterogeneous industrial networks and an implementation method. Background technique [0002] With the increasing maturity of wireless network communication technology, industrial wireless networks are gradually penetrating into the industrial field, showing a development trend from information collection to production control, from local solutions to whole network solutions. However, due to the complex industrial site environment, limited coverage of industrial wireless networks, and strict requirements on network reliability and stability, it is usually necessary to deploy multiple industrial wireless networks and various wired networks in a factory area to realize the entire factory area. network coverage, which makes the integration management among heterogeneous industrial networks a difficult problem.
