Research On Traffic Scheduling Mechanism In Industrial Network Based On SDN Intelligence

Software Defined Network(SDN)is a new network architecture that can virtualize network resources and decouple the network control layer from the data plane to achieve flexible control of network traffic,which enables traffic scheduling more intelligent.Based on the advantages of SDN architecture and the current environment of industrial Internet,this paper proposes a new industrial network architecture,and proposes a traffic scheduling mechanism based on resource auction.This paper studies the current status of the industrial Internet first,and finds that the current industrial Internet will not be able to meet the network QoS(Quality of Service)if it does not change and expand to the WAN.If you want to completely subvert from the original network architecture,it will cost a lot.Therefore,based on SDN technology,this paper adds the concept of SDN Intelligence in the original industrial Internet architecture.In SDN Intelligence,this paper uses block chain intelligent contract technology to enable different SDN sub-controllers to conduct resource auctions autonomously,in order to determine the priority of different services for different types of resources,and to form a function that is connected by different resources.For the queues formed by various functional service chains,this paper uses a multi-hop model including a priority scheduling model and a QoS framework model to ensure that the queues meet the reasonable scheduling in industrial QoS.Finally,by using the lab server to build the test environment,the function of block chain issuing and controller resource auction is realized.It is determined that the scheduling mechanism of this paper can be used to carry more traffic than the traditional method.
