The document discusses the history and architecture of intelligent networks. It outlines how intelligent networks provide added value through open standards, vendor independence, and centralized management. The key question is how intelligence is distributed in the network, with the IN conceptual model providing a framework. Advantages include cost effectiveness and efficient services, while disadvantages include potential single points of failure.

3. INTRODUCTION Intelligent Network offers added value Open standards, vendor independence Rapid service creation and deployment Customized services to users Centralized service management New opportunities to make business i.e. new services, markets and customers Rapid adaptation to market needs and competition

5. The key question is: How Intelligence is provided and distributed in the network IN Conceptual Model (INCM) gives a framework which will be presented here Other models may emerge, most probably from voice, multimedia and mobile value added services in Intranet and Extranet Future broadband intelligence standards will be chosen by the market

10. DISADVANTAGES The non-IN telecom network is the ultimate distributed system, and it has served operators well. There is no single point of failure, so its number one functional priority - to remain constantly available - has historically been met reliably.

11. CONCLUSION The main idea behind two process is decentralization . The communication delay is reduced at the cost of increased intelligence at the local level. If collaborative intelligence exceeds combinatorial complexity then there is no need of communication between controller and requirements of central process. Thus the performance matches to that of the centralized MIMO system.
