VPNs Gain With Users; Frame Relay Declines.

This article reports that corporate purchases of Internet protocol virtual private network (IP VPN) services continue to surge forward in the U.S., a trend that analysts said is being accompanied by a shift away from the use of frame-relay technology to carry network traffic. Information technology executives who are rolling out IP VPN connections said that the networks provide better security than dial-up systems and many other current approaches. They added that VPN can also help keep networking costs in check, allowing them to vastly increase bandwidth to handle new applications.
