Virtual private data network service in the wide area networks

Abstract

A technique is presented to satisfy the demand for customized user service through virtual private data networks (VPDN). It is reported that VPDN allows the creation and management of software defined private networks within the confines of the wide-area network (WAN). This solution is economically advantageous to customers because these private networks do not require capital investment in communication equipment. Its flexibility allows service providers to quickly introduce customized network environments. Virtual private data networks are secure, simple to manage, and easy-to-use.<>
