| Abstract | Intelligent Network is an architectural concept which provides a functional approach to a network implementation, independently of the underlying infrastructure. Nevertheless, such infrastructure is subject to technological evolution, and one may consider taking benefit of new network facilities in order to implement a new service (e.g. ATM broadband network features, interactive TV). Hence whenever a new service or feature is introduced, the question arises again: does that new service or service feature have to be either implemented by means of an IN architecture, or introduced as an improvement of the underlying network and/or switch-based capabilities? In Some criteria, related to functions available in an Intelligent Network architecture, can be found to help answer such a question from the service designer point of view. - Does the service need triggering points during the Call Processing (trigger function within SSF)? - Does the service need sophisticated switching functions that require SSF be commanded by SCF? - Does the service present a complex logic that justifies externalisation in the SCF? - Do the service data, whether due to their complexity or for consistency purposes, need to be structured in database as permitted by the SDF? - Does the service execution need external resources (access to other networks, specialised device ... ) as permitted by the SRF? - Does the service present special interworking requirements regarding a set of homogenous and consistent integrated services? The consequences of answering these questions are not so trivial: in fact, it helps to draw the border between what is considered as a service feature (a so-called value-added feature of the network) which is to be, sooner or later, independent from the network infrastructure, and what is considered as a core characteristic of the underlying network itself (so-callcd the transport network) which must be incorporated to the network infrastructure, hence evolving together with such infrastructure. Such a border can be used to delimit the network operator's domain and the service provider's domain. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
