Design And Implementation Of Virtual Machine Dynamic Migration Network Based On VXLAN

With the rapid growth of new technologies and applications such as cloud computing,mobile interconnection,big data and other new technologies and applications,the number and scale of Internet data centers are growing rapidly.To realize the reliable operation of data centers,and the rational utilization of resources has become an urgent problem.The construction of double live data center to realize the high reliable operation of data center and the realization of multi-data center resource sharing become the mainstream solution.In this paper,based on the construction process of the company under construction,aiming at the migration requirements of cloud platform across data centers,this paper deeply analyzes the realization of VXLAN technology characteristics for cloud platform resource sharing,through the comparison and selection of VXLAN technology with different control layer technologies,and finally chooses the technical architecture of EVPN VXLAN to build the core network of cross-regional dual-live data center.After the completion of the project construction,through the function and performance test,confirm to meet all the requirements of the project construction.In this paper,the research,analysis and design and implementation are carried out from the following aspects:(1)Firstly,the basic principle and implementation function of VXLAN technology are deeply analyzed,and the advantages of using this technology to build the second layer network,as well as the data communication process of different networking modes of the technology.(2)Secondly,according to the requirements of project implementation,comparing VXLAN technology with different control layer technology Differences in implementation functions,BGP EVPN is selected as the control level of VXLAN,and the implementation of host information announcement,ARP information notification and routing information update notification by EVPN.Based on the best practice,choose the most cost-effective network scheme suitable for the company's demand.(3)Finally,review the implementation process of the project,present the whole process of using the EVPN VXLAN mode network implementation,as well as the project function test,including the data center cloud platform host communication test,virtual machine cross-regional implementation of online migration test,the test results meet the construction needs.Through the construction of this project,the online migration function of the virtual machine of cross-regional data center is realized for the first time,which improves the reliability of the data center carrying business,at the same time,improves the reuse rate of resources of cross-regional data center,saves the cost of data center construction,and accumulates valuable experience for the company's data center construction.
