Many technologies can implement VPN , these technologies include PPTP ( Point-to-Point Tunneling Protocol );

很多技术都可以用于VPN的实现，比如PPTP协议（Point-to-PointTunnelingProtocol，点到点通道协议）；

Lets get the PPTP module installed so that we can start creating VPN connections .

我们来把PPTP模块安装上来以便我们能开始创建VPN连接。

By analyzing the characteristics of construction and the PPTP data frames , the performance of VPN experiment net was tested .

通过协议和数据帧分析，对实验网进行了性能测试。

Now that you have the PPTP module installed for your Network Manager , let 's get a connection setup .

既然你已经为你的网络管理器安装好了PPTP模块，那我们就来设置一个连接。

The PPP protocol , the basis of PPTP and L2TP protocols , is also expounded .

重点比较了几种用于实现VPN的安全协议的优缺点，并详细阐述了PPTP和L2TP协议的基础：PPP点对点协议。

The Point-to-Point Tunneling Protocol ( PPTP ) is used to secure PPP connections over TCP / IP link .

点到点隧道协议（PPTP）是用来保证TCP/IP上的PPP连接安全的。

It can implement some security protocol - such as IPSec , PPTP , SSL , IKE .

它可以代替软件来实现一些安全通讯协议，如IPSec，PPTP，SSL，IKE等等。

Because network security is taken into account by more and more people , VPN based on PPTP is designed on heterogeneous platform and applied to remote supervisory and control system .

由于网络安全越来越受到人们的重视，本文在异构平台下设计了基于PPTP的VPN网络并应用于远程监控系统。

VPN technology can be implemented by many security protocols on different network layers , such as PPTP on data link layer , IPSec on network layer , SOCKS on session layers and so on .

VPN技术能够被多个网络层次上的安全协议所支持，如数据链路层上的PPTP，网络层上的IPSec，会话层上的SOCKS等。

The author analyzes L2 Tunneling Protocol PPTP and L2TP from the angle of protocol and points out their technical differences in application , hoping to provide basis for the selection of VPN application scheme .

从协议平面的角度对数据链路层隧道PPTP和L2TP进行了分析，指出了它们在应用中的技术差异，为选择VPN应用方案提供了依据。

After introducing the correlative knowledge of VPN , such as TCP / IP protocols , Encryption technology and so on , the article discusses in detail the IPsec protocol and the two main protocols of VPN : PPTP and L2TP .

本文在介绍TCP/IP协议、加密技术等与VPN相关知识的基础上，较详细论述了IPsec协议和VPN的两个主要协议：点到点隧道协议（PPTP）和层2隧道协议（L2TP）。
