Tunneling allows the transmission of data through a public network such as the Internet so that nobody can know what kind of data is being transmitted. Tunneling is generally done by encapsulating the private network data (creating a virtual private network or VPN) and protocol information within the public network protocol data so that the tunneled data is not available to anyone examining the transmitted data, thus making it very secure.
A Virtual Private Network (VPN) is often understood as a network within a network. VPNs use tunneling to transmit private communications over public lines so, for example, a corporation can use the public Internet as it's private wide area network simply by installing VPN hardward and software to manage the connections between data centers or between computers. A VPN system depends on fairly complex low-level networking technologies including specialized protocols. VPNs require careful planning on behalf of the companies that choose to implement them. Virtual Private Networks, properly implemented, can offer tremendous advantages to businesses operating in multiple geographies.
