VPN(Virtual Private Network),即虚拟专用网络。它是通过对网络数据的封包和加密传输,在公网上传输私有数据、达到私有网络的安全级别,从而利用公网构筑成为的。VPN能够支持通过Intranet和Extranet的任何类型的数据流,方便增加新的节点,支持多种类型的传输媒介,可以满足同时传输语音、图像和数据等新应用对高质量传输以及带宽增加的需求。
目前常用的VPN安全保证技术有四种:隧道技术(Tunneling)、加解密技术(Encryption & Decryption)、密钥管理技术(Key Management)、使用者与设备身份认证技术(Authentication)。
现有的VPN种类有:基于PPTP/L2TP,基于MPLS,基于IPSec,基于GRE,和基于SSL的VPN。
而MPLS VPN,即 ,多协议标签交换虚拟专用网推出了一种对等模式,可以支持大规模 IP VPN 实施。这种模式极大地简化了 VPN 客户和服务供应商的路由和可管理性,与此同时,确保了 VPN 间的正确隔离。

VPN (Virtual Private Network), namely hypothesized private network. Itis through to the network data wrapped gift and the encryptiontransmission, in the male on-line transmission private data, achievesthe private network the security rank, thus uses the male net toconstruct into. VPN can support through Intranet and the Extranet anytype data stream, facilitates increases the new pitch point, supportsthe many kinds of types the transmission medium, may satisfysimultaneously transmits the pronunciation, the picture and the dataand so on the new application the demand which increases to the highgrade transmission as well as the band width.

At present the commonly used VPN safe guarantee technology has fourkinds: The tunnel technology (Tunneling), adds the decipher technology(Encryption & Decryption), key management technology (KeyManagement), user and equipment status authentication technology(Authentication). The existing VPN type includes: Based on PPTP/L2TP, based on MPLS
