What's new in intelligent networking?

Abstract

This paper looks at current directions of intelligent network (IN) implementations and possible changes resulting from the latest concepts of information networks. By way of introduction, the paper reviews the historic introduction of intelligence in telephone networks which has led towards the emergence of 'classical' IN principles. It then looks briefly at expectations for future evolution of public network intelligence. Classical IN principles have typically set the scene for network operators' IN implementation strategies, increasingly using the ITU CS1 as an initial requirement template. However, whilst there is general agreement that CS1 provides a working framework for the short-term, the contents of future ITU Capability Sets are less clear in definition. Meanwhile, operators are finding that the complexity of existing transport networks is increasing because of new embedded service solutions introduced to meet short-term service needs. There is a growing awareness, in the face of expected future service demands, that the traditional IN approach has limitations. Consequently, some operators are seeking to readjust and clarify their targets for their evolutionary strategies. There is a growing expectation that the work being done in the TINA Consortium is rapidly laying out the basis for the future telecommunications architecture principles.
