Toward QoS-capable Electronic Private Systems
You might know very well what a VPN, or Digital Personal Network, is; you probably don??t use one. These providers are beginning to offer IP connectivity and consulting products and services to support consumers build and control their own IP-VPN, and then hands it in return to the customers to function.
