Experts answer:VPN is VirtualPrivateNetwork acronym, translated into Chinese virtual private network. VPN is "virtual private network", which is in the public network infrastructure to build a logic circuit, rather than the traditional end to end network cable connection. Now VP N technology is very important applications, such as your company is large, both in Beijing and Guangzhou office, when you want to go to the other party office enterprise LAN through the VPN this technology can bring distant 1000 Hill 10000 LAN between water "fight" into a network, visit their Board as if the visit Net domain of "neighbors" as, of course, the technology of its cost is quite considerable in the ~ ~ ~ ~ Er wireless VPN to my understanding, as if through a fully software solution to achieve, just like Li Yong proxy servers, by a gratuitous server VPN service to another website Or network, as if the same access to resources in the network segment, it can not be restricted. (According to the meaning below to understand September 20 message, Google today announced wireless VPN service, the service is called GoogleSecureAccess (Beta), with Users only need to http: ** wifi.google.com * download.html download and install a software, opening it will automatically connect to the Wifi wireless Google's VPN server. It is reported that all of the Internet connection on all encrypted, and transmitted Declassified after the machine, enabling the connection of the security. Although Google claims that the software currently only available for download in the San Francisco area, but has been tested in China can download. Prior to this, for the maintenance of internal network security needs, Google in China is limited, but GoogleSecureAccess software through easy to use, in theory, you can open any restricted site, seriously undermine the hard-won domestic network environment clean! ) VirtualNetwork meaning there are two, one VPN is built on the existing physical network Above, and the physical network independent of the specific network architecture, users generally do not care about the physical network and equipment; second VPN users see when using the VPN is a pre-defined set of dynamic networks. PrivateNetwork meaning there are two, one that built all VPN Users can reach the public network, especially Internet, but also PSTN, Frame Relay, ATM, etc., when in a line be constructed as consisting of private network VPN, the relative VPN is also a "public network"; second VPN will establish a private network, or as private networks, to ensure that mention For secure network connection, it must have several key functions: authentication, access control, encryption and data integrity. A network connection generally consists of three parts: client, transmission media and servers. VPN is the same, difference is that VPN connections use the tunnel as a transmission channel, relies on the data packet Packaging and encryption. WAN VPN is a fast connection to establish interconnection and access tools, but also a strengthening network security and management tools. VPN based on the user's physical network, incorporating the user's network application systems. VPN technology covers more than technical expertise, different application areas Application of technology and products are very different. screen.width * 0.35) this.width = screen.width * 0.40 "*
