The Design And Implementation Of Remote Control Environmental Based-on OpenVPN

With the high-speed development of the Internet, the remote control as an importantapplication of network technology, has attracted the high attention of people. In theenterprise, the practical application of the remote control is quite extensive. A newgeneration of SSL VPN technology compared with the traditional complex IPsec VPN andthe expensive MPLS VPN turns out to build more secure and efficient remote controlenvironment.The DATE is able to take advantage of the network for data transmission of anembedded industrial equipment. The DATE in most of the scene environment is very bad,and there is no effective network transmission medium, even if the use of mobile networksignal, it assigned to developers Intranet IP, which makes it impossible to the corporatenetwork remote control instrument for the amount of far side, once the problems appearedin the process of data transmission, can arrange maintenance personnel on a business trip,if we can’t solve software problems have caused data loss, it will also produceimmeasurable loss.To solve above problems, this paper analyzes a method of constructing the remotecontrol of the construction of small and medium-sized enterprise environment, whichbased on virtual LAN technology and SSL VPN technology, open source project,OpenVPN. Firstly, this paper introduces the research background and the research statusand development trend at home and abroad of VPN technology, then analyzes from theaspects of data security OpenVPN working principle and related technologies. Secondly,combining the actual situation of the small and medium size, describes in detail from theOpenVPN remote control environment analysis and design to implementation, and to testthe process in detail. The realization of several mining instrument OpenVPN GUI client using Qt development framework, pressure test to the server using LoadRunner testautomation tools. Now, using OpenVPN remote control environment has been successfullyapplied in the practical work. So far, it has helped the company save a lot of expenses,and effectively improve the use of several mining instrument customer and the currentsituation of the company’s maintenance staff miscommunication.The Internet of things era has come, the remote control environment accessed theembedded system makes the information such as household appliances, industrialequipment, remote terminal, diversity of intelligence. It has become the inevitable trend ofdevelopment.
