For all advantages of frame relay for enterprise networking, a more flexible and cost-effective solution is required for the next wave of e-business. Enterprises and services providers should be looking more closely at IP VPN solutions as the base enterprise architecture of the future. This 16 page document was written by TeleChoice, Inc. for Nortel Networks and looks at some of the qualitative and quantitative benefits of IP VPNs. IP VPNs are fast becoming essential in service provider portfolios and enterprise network architectures. While frame relay has been the work-horse technology for the enterprise community to date, IP VPNs are proving they can deliver significant advantages—qualitative and quantitative. Service providers that have not yet started down a path towards offering an IP VPN service do so at their own peril. TeleChoice believes that the Contivity VPN switch from Nortel Networks can help service providers and enterprises exploit the business potential of the Internet.
