Abstract

Existing technologies, including frame relay and ATM, can be used to create virtual private networks (VPNs) over a shared infrastructure. However, two new technologies, tag switching and IP security, may be used to create IP VPNs that are independent of the access network and the core technology. This paper examines these technologies, compares them to each other and to existing technologies, and highlights the benefits of their use in comparison to legacy technologies.
