Perspective
In the absence of state-operated telecommunication sector, "Value-added Network Service" still is used, mainly as a functional description, in conjunction with dedicated leased lines for B2B communications (especially for EDIFACT data transfer).
Governments like South Africa still maintain explicit regulation while others address specific services with licensing.
Traditionally, most VANs primarily only supported general-purpose B2B integration capabilities focused on EDI but service providers are evolving to become more process- and industry-specific over time, particularly in industries such as retail and hi-tech manufacturing. Some sources suggest that modern VANs should be called "Trading Grids" due to commonalities with Grid computing. Others, such as distinguish into "Internet Service Providers" (ISPs) and "International Value-Added Network Services" (IVANS) operators.
