Abstract

The invention relates to an intentional industrial SDN northbound interface system supporting data scheduling and an interaction method and belongs to the technical field of the industrial network. Onthe basis of fully considering characteristics of heterogeneous industrial network services, when network administrators deploy the complex network services through using ordinary northbound interfaces, they face problems such as the complex network configuration process and interface function limitations, so the intentional northbound interface system with certain self-determination capabilitiesis added between the control layer and the application layer, the complex configuration process in the industrial network is blocked, moreover, on the basis of the system, a set of intentional northbound interfaces are provided for services such as deterministic scheduling of data and transmission reliability guarantee, decoupling of the network technology and the network interfaces is realized,and business deployment difficulty is reduced.

Description

technical field

[0001] The invention belongs to the technical field of industrial networks, and relates to an intentional industrial SDN northbound interface system and an interaction method supporting data scheduling. Background technique

[0002] SDN (Software Defined Network, Software Defined Network) is an emerging network architecture, which physically decouples the highly coupled control plane and data forwarding plane in the traditional network, and realizes the control plane to the network through a unified southbound interface protocol. Centralized management and control of underlying network devices has brought about a revolution in the network field. As an important connection between the application layer and the control layer, the northbound interface is an important link for users to deploy network services and change network configurations. Currently, northbound interfaces can be divided into functional northbound interfaces and intentional northbound interfa...
