The Intelligent Network (IN)  is the standard network architecture specified in the ITU-T Q.1200 series recommendations. It is intended for fixed as well as mobile telecom networks. It allows operators to differentiate themselves by providing value-added services in addition to the standard telecom services such as PSTN, ISDN on fixed networks, and GSM services on mobile phones or other mobile devices.

A service-oriented architecture (SOA) on tarkvarainvesteeringute stiil, kus teenuseid pakutakse muude komponentide kaudu rakenduse komponentide kaudu võrgu sideprotokolli kaudu. Teenusepõhise arhitektuuri aluspõhimõtted ei sõltu müüjatest, toodetest ja tehnoloogiatest.
  1. Business value is given more importance than technical strategy.
  2. Strategic goals are given more importance than project-specific benefits.
  3. Intrinsic inter-operability is given more importance than custom integration.
  4. Shared services are given more importance than specific-purpose implementations.
  5. Flexibility is given more importance than optimization.
  6. Evolutionary refinement is given more importance than pursuit of initial perfection.
