8.1.6 From SCP’S to Stand-By Servers

The service control points (SCPs) discussed further in the chapter had been essential to provide the early IN functions have been replaced gradually by servers and lookup databases. The lookup function remains; when a network service is requested, the SCP provides the supplementary data, address, or methodology (programs, utilities, etc.), to complete the request. Such supplementary information can be stored in any database and servers can take over the SCP functions, especially in small networks. The service can indeed be any type of service and the role of servers in any network is that of providing supplementary information to complete any task or function.

The seminal American Telephone and Telegraph Co. (AT&T) patent (Weber, 1980) for IN is based on the inclusion of real-time database capabilities in communication networks. Address lookup of circuit-switched connections of plain old telephone service (POTS) to dynamic path routing of SONET frames is routinely done by the fast high-volume servers in networks.
