INTRODUCTION
This article describes the technologies used to build virtual private networks (VPNs). A classification of VPNs is proposed, identifying those that require interaction with a telecom operator's network and those that can be built independently of the transport network.
The article focuses on the main technologies operating at Layer 2 or Layer 3 of the OSI model: IPSec, L2TP, GRE and MPLS. The architectures and services associated with these architectures are also analyzed.
