Virtual Private Network
A Virtual Private Network (VPN) is a computer network in which some of the links between nodes are carried by open connections or virtual circuits in some larger network (such as the Internet), as opposed to running across a single private network. The Link Layer protocols of the virtual network are said to be tunneled through the larger network. One common application is secure communications through the public Internet, but a VPN does not need to have explicit security features such as authentication or content encryption. For example,VPNscan also be used to separate the traffic of different user communities over an underlying network with strong security features, or to provide access to a network via customized or private routing mechanisms.[1]
