- Feb 22, 2019-

A virtual private network (VPN) refers to a technology for establishing a private network on a public network. It is called virtual network, mainly because the connection between any two nodes of the entire VPN network does not have the end-to-end physical link required by the traditional private network, but is the network provided by the public network service provider. Platform, such as the logical network above the Internet, ATM (Asynchronous Transfer Mode), Frame Relay, etc., user data is transmitted in a logical link. It covers encapsulation, encryption and identity across shared or public networks. Verify the extension of the linked private network. VPN mainly uses tunnel technology, encryption and decryption technology, key management technology and user and device identity authentication technology.

(2) The transmission data is safe and reliable - the virtual private network products adopt security technologies such as encryption and identity verification to ensure the reliability of the connected users and the security and confidentiality of the transmitted data.


(3) The connection is convenient and flexible - if the user wants to network with the partner, if there is no virtual private network, the information technology departments of both parties must negotiate how to establish a leased line or frame relay line between the two parties. After the virtual private network, only Both parties can configure secure connection information.


(4) Full Control - Virtual Private Network allows users to take advantage of ISP's facilities and services while fully controlling their network. Users only use the network resources provided by the ISP. For other security settings and network management changes, they can be managed by themselves. You can also create a virtual private network within your company.
