The Design And Implementation Of A Dispatching System For Data Center Outlet Based On SDN

With the rapid development of network technology,access to the Internet more and more devices,the network traffic is more and more,in the face of more and more network traffic,the traditional network overwhelmed,so the new network architecture came into being The Software Defined Network(SDN)is generated in such an environment,SDN uses the idea of control and forwarding,which is one of the characteristics of data plane and control plane separation,the data plane is responsible for data forwarding,and The control plane is responsible for the processing of the logic.This gives the network architecture more development and flexibility,for the network architecture to show a new look.The purpose of this paper is to design and implement SDN data center export traffic dispatching system based on SDN.The SDN data center export traffic dispatching platform is designed to complete the SDN traffic scheduling architecture design and function design.Based on these,the project application In practice.This paper first describes the current situation of SDN and traffic scheduling of conventional methods,which stand in a new perspective to traffic scheduling.The use of SDN technology combined with the needs of customers to meet customer network resources,flexible scheduling,to achieve a reasonable allocation of network resources.Then,the demand analysis of SDN data center export traffic dispatching system is carried out,including the functional requirement analysis of the system and the nonfunctioning analysis of the system.And then the SDN data center export flow scheduling of the various modules for detailed design,including the configuration of the parameters of the design,topology generation design,routing scheduling design and routing design.And then the implementation of SDN data center export traffic scheduling,including the realization of parameter configuration,the realization of topology generation,the realization of routing and routing and routing implementation.Finally,the basic functions and performance of the system are tested to verify the feasibility of the scheme adopted in this paper.Through the use of SDN related technology,greatly facilitate the network management personnel to the network management,the system uses BMP reported data to achieve the construction of the network topology,while the data center to the ISP operator routing scheduling provides an effective scheduling.
