With the continuous deepening and development of the information age, many names and code names of information professions have appeared, such as "virtual private network". So what is a virtual private network, let us learn and understand together!
The function of a virtual private network is to establish a private network on a public network for encrypted communication. Virtual private network technology is widely used in enterprise or industrial networks. The virtual private network gateway realizes remote access through encryption of data packets and conversion of destination addresses of data packets. A virtual private network can be implemented through servers, hardware, software, etc.
A virtual private network is to use a public network to set up a private network for remote access technology. For example, when an employee of a company travels to other places, he wants to access the server resources of the company's internal network, which belongs to the remote access private network. In the traditional enterprise network configuration, remote access is the traditional way of renting DDN (Digital Data Network) leased line or frame relay, which will inevitably lead to high network communication and maintenance costs. For mobile users (mobile office workers) and remote personal users, they usually enter the enterprise's global area network through dial-up lines, but such a global area network is inevitable.
To allow remote employees to access internal network resources, the solution to using VPN is to set up a virtual private network server in the internal network. After remote employees connect to the Internet locally, they can access the virtual private network server through the Internet connection, and then access the internal resources of the enterprise through the virtual private network server. In order to ensure safe and stable data transmission, the communication data between the virtual private network server and the terminal computer is securely encrypted. With data encryption, we can think that data is transmitted securely over a dedicated data link, just like setting up a dedicated network. With virtual private network technology, users can use virtual private network to access intranet resources as long as they have network conditions, whether they are traveling in different places or working at home. This is the reason why virtual private network is so widely used in enterprises.
Industrial virtual private network router to realize remote data collection of industrial control equipment
Remote monitoring of industrial equipment is one of the main applications of the Industrial Internet of Things, which can realize comprehensive perception, dynamic transmission and real-time analysis of equipment data. At present, large-scale deployments have been carried out in power stations, base stations, hydrological stations, and remote sensing in mountainous areas. With the popularization of urban digitalization and industrial automation, tasks in key industries will increasingly rely on industrial automation. Under complex and harsh industrial conditions, it is extremely difficult to collect data from industrial control machines. Since the on-site environment is outdoors, it is usually impossible to connect to the network through complicated fiber optic cables, and a wireless network card is usually used to connect to the Internet. Basically, there is no public IP address to access the Internet through the wireless network card.
Zhilian IoT industrial routers can solve the above problems. Install Zhilian IoT industrial routers in various places, and form a virtual LAN network through the data collection center to collect the data information of on-site terminal devices in real time and transmit them to the data remotely. The processing center conducts unified management.
First, connect the Zhilian IOT router to the power supply, insert the SIM card into the card slot; access 192.168. Just go online. As the core component of data collection, Zhilian IoT intelligent networking is at the core of data information collection and remote data transmission. A good data collection solution can liberate operation and maintenance personnel from heavy data processing work, real-time data Acquisition also enables the system to truly realize real-time transmission to the central control room.
Using the Zhilian IoT industrial router solution can help data collection to maximize its functions with fewer resources, and subsequent data collection only needs to be added to the original network. The compatibility of the network protocol is very strong, which is different from the nature of the traditional virtual private network (which needs to rely on broadband to allocate public network IP). By connecting to the Internet through a wireless 5G/4G/3G network, you can easily create a virtual local area network, so that data from all over the world can be interconnected.
