Value-Added Networks (VANs)
Already have a Gartner account?
Traditional Value-Added Networks (VANs) continue to be challenged and, in many cases, supplanted by Value-Added Internets (VAIs), Integrated Communications Providers (ICPs), and even Application Service providers (ASPs), all of which can often provide more robust features and capabilities at lower prices. User migration from X.25 networks to more robust frame relay, ATM, and Internet network offerings is increasing. The term Value-Added Network itself is becoming confusing and outdated, being replaced by more popular industry terms and buzzwords revolving around e-business/e-commerce and general business-to-business IP services. Virtually every telecommunications network service vendor now claims to offer value-added services of some kind or another. Whatever they are called, these networks continue to be widely used by the government and by various industry groups, as well as by large corporations in conjunction with their distributors, suppliers, and other trading partners.
