Traffic of Various User Communities Over a Secure Underlying Network

An enterprise private network is a network that a single company creates to connect its office locations (such as production sites, head offices, remote offices and shops) in order for them to share computer resources. A Virtual Private Network (VPN) is an overlay network in which some of the connections between nodes are carried by open connections or virtual circuits in a larger network, such as the internet, rather than by actual wires. When this is the case, the virtual network's data link layer protocols are referred to as tunnelling through the larger network. Secure communications over the public Internet is one common use, but a VPN does not necessarily need to have explicit security features like content encryption or authentication. VPNs, for instance, can be used to separate the traffic of various user communities over a secure underlying network.
