Research On Sdn Regional Networking And Application Based On Collaborative Architecture Control

Software Definition Network(SDN)divides the network into architecture control layer and data layer,which is an important research topic in the field of computer network architecture.Nowadays,SDN network separates the architecture control layer from the data layer of network equipment,and centralizes the management by external architecture controller.Network equipment only carries out the action of packet transmission,which simplifies the management of equipment.SDN transfers network management authority to architecture controller software of architecture control layer,and adopts centralized control mode,so it is more suitable for flexible and fast network application requirements.Based on the in-depth study of SDN regional networking,this paper focuses on the research of SDN and its related technologies,cooperative architecture controller,and the performance test and comparative study of traditional switches and SDN switches.The use of resources in network architecture is very important for enterprises.In this paper,a design scheme of SDN regional networking based on Cooperative architecture control of associated gateway is proposed to maximize the use of server resources in network.Experiments show that the introduction of SDN under cooperative architecture control can solve many problems of constructing virtual network in traditional architecture,and it is more flexible.Because of the low CPU frequency of SDN switch,this operation greatly reduces the encapsulation processing speed of the switch,and increases the partition and transmission delay caused by the encapsulation component.This process may lead to the repeated transmission and loss of the package component,which makes the SDN switch less efficient than the traditional switch.A modified Rules mode in OpenFlow is proposed.The load capacity of servers is adjusted dynamically to achieve load balance between servers,so as to improve the utilization of resources in the network architecture.The experimental results show that the proposed method can significantly improve the utilization of resources in the network architecture.The experimental scheme based on cooperative architecture controller has the advantages of clear structure,flexible scheduling,good expansibility,strong adaptability and open standards,which can better meet the development needs of the current network.In this paper,the cooperative architecture control mechanism is used to solve the multi-domain architecture control problem in regional networking,which can ensure the effective realization of network performance and function.
