| Abstract | Summary form only given. When AT&T bid on the US federal government's new private network called FTS-2000, it was clear that competition between service providers bidding on this contract would be intense. To win this contract, it was realized that this network would have to be robust, reliable, provide a wide array of services, and be very efficient. It was therefore decided to adopt a dynamic nonhierarchical routing (DNHR) traffic architecture, which had proved economical and successful in the AT&T public switched network during the mid-1980s. In this case DNHR had to be adapted to the eighteen 5ESS/sup TM/ switches which would form the backbone of the FTS-2000 network. The adapted routing strategy was called DFR, dynamic flexible routing, which like DNHR took advantage of diverse customer calling patterns over a wide geographical area in this nationwide network serving four time zones. Due to the substantial increase in the network load the planners realized the need for an agile, short-term planning tool adapted to the volatile FTS-2000 environment, and thus the system called PATTERNS was developed. PATTERNS incorporates the same network design algorithm used for DNHR, in which the efficiency of routing pattern changes often makes it possible to accommodate moderate new traffic loads and avoid adding new circuits altogether. |

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.
