| Abstract | In optimal QoS provisioning all traffic flows are distributed among LSPs (label switching path) related to service classes. The congestion of concurrent flows (traversing the network simultaneously) can appear. For LSP creation the IGP (interior getaway protocol) uses simple on-line routing algorithms (e.g. OSPFS, IS-IS) based on shortest path methodology. In highly loaded networks it becomes insufficient technique. On other hand, constraint based explicit routing (CR) ensures traffic engineering (TE) capabilities. It may find a longer but lightly loaded path, taking care of congestion possibility. In this approach LSP can be pre-computed much earlier, possibly during SLA (service level agreement) negotiation process. An effective algorithm for congestion control is developed. It could be a very good solution for congestion avoidance and for better load-balancing purpose where links are running close to capacity. Significant improvements are possible through heuristic approach based on restrictions for capacity state value. Comparisons of results are discussed. |

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.
