Abstract

The invention discloses an industrial software defined network slicing method based on edge collaboration, which relates to the field of network information and comprises a field equipment layer, an edge layer and a network configuration layer. The network configuration layer constructs different network slices according to business service types, and the network slices not only comprise virtual network files and logical topologies mapped by bottom physical entities, but also comprise specific distribution of network resources; the network configuration layer communicates with the edge layer through an industrial Ethernet, receives available resource information and state information subjected to data processing, and issues a control instruction and resource pre-distribution information; and the edge layer is in wireless communication with the field layer, receives the state information acquired by the field layer, and transmits a control instruction or flow scheduling information. Through adoption of the network planning and communication, calculation and cache resource joint scheduling method, the system power consumption is minimized while different service control performance requirements are ensured, and the resource utilization rate and the system performance are improved.

Description

technical field [0001] The invention relates to the field of network information, in particular to an edge collaboration-based industrial software-defined network slicing method. Background technique [0002] With the advent of the Internet of Things era, the traditional industrial control network architecture with split layers has rigid end-office networks, single business types, and cannot meet the needs of efficient processing of massive nodes, seriously hindering the efficient interconnection of information. It is urgent to build a new flat network The industrial control network architecture conforms to the development trend of the factory intranet towards the integration of information technology (IT) and operational technology (OT). Software-defined networking (SDN) has the characteristics of separation of control and forwarding, open application programming interface (API), and centralized control. It can realize seamless integration of applications and networks, obta...
