Research And Design Of Enterprise Network Performance Optimization Based On DPDK

With the rapid development of the mobile Internet and the continuous increase in transmission speed,the number of users in enterprises has increased dramatically and the size of traffic in the network has continued to increase.Relying on traditional methods to increase network bandwidth and increase network throughput has been unable to meet the current needs of enterprises.With the advent of SDN technology and the continuous upgrading of high-performance packet hardware processing technologies,although the company's demand for data processing has been largely solved,it still does not completely solve the problem of high traffic and high concurrency that occur in enterprises.This paper combines the current network processing performance issues in the enterprise,in-depth Zhengzhou Jingan Network Technology Co.,Ltd.to investigate the current network needs in the enterprise,and analyzes the current performance bottlenecks in Jingan's network architecture.The DPDK-OVS load balancer based on DPDK is researched and designed.It replaces a single network node by clustering and achieves the purpose of improving network node processing performance.First of all,this paper investigates the progress and current status of high-performance packet processing at home and abroad,and clarifies the content of this research project and the related work that needs to be done;second,it introduces the related technologies involved in this project including the load.Balanced,VXLAN,DPDK,and OVS technologies;then,focusing on the current network architecture of Jingan,analyzing the existing problems in the current architecture,and designing a DPDK-OVS load balancer in conjunction with the current mature network technology.The network node relieves the CPU load of the network node and optimizes the performance of the network node.Then,this paper does two aspects of testing work.On the one hand,it tests the DPDK forwarding performance and confirms the DPDK's data forwarding performance through three sets of tests.Performance advantages.On the other hand,the network architecture based on DPDK was tested.By testing the load of CPU,it was confirmed that the new network architecture had achieved the optimization of data processing performance.Finally,the work of this paper was summarized and the future work was expected.
