Resource allocation method and system for industrial time-sensitive software-defined network

Abstract

The invention provides a resource allocation method and system for an industrial time-sensitive software-defined network. The network resource allocation method and system are used for supporting different QoS (Quality of Service) requirements of various service types in an industrial SDN (Software Defined Network). The system mainly comprises a network state monitoring module, a network state analysis module, a network resource planning module and a resource allocation execution module. The resource allocation method provided by the invention is a secondary resource allocation mechanism; according to the method, firstly, different network resource pieces are allocated to different types of services, then queuing is conducted according to different priorities of similar service flows, transmission time windows are allocated, it can be guaranteed that the different types of services can be transmitted normally, and meanwhile the QoS requirements of the similar services with the high priorities are met. Through the method and the system provided by the invention, the optimal network resource can be distributed to the industrial time sensitive network, QoS requirements of different applications are met, and the instantaneity and the resource utilization rate of the network are improved.

Description

Technical field [0001] The invention relates to the field of industrial network resource management, and more specifically to a resource allocation method and system for industrial time-sensitive software-defined networks. Background technique [0002] Traditional industrial networks use a fixed resource allocation model, that is, all business requirements are implemented on the same physical network, which leads to low resource utilization and network inflexibility. With the continuous development of information and communication technology, industrial networks are becoming more and more open, and the types of services carried by the network are increasing. Traditional resource allocation models are difficult to adapt to new network requirements. [0003] The emergence of Software Defined Network (SDN) provides new ideas for improving the flexibility of manufacturing systems. SDN separates the data forwarding plane from the network control plane, and dynamically reconstructs the n...
