| Abstract | Multipoint-to-multipoint virtual connections in communication transport networks can be defined through a network management system where they can be computed as a tree which interconnects a given subset of network nodes. This problem can be modelled as a Steiner tree problem ii graphs with the aim of obtaining the lowest-cost tree for interconnecting the subset of network nodes involved in each multipoint-to-multipoint virtual connection, where the cost can represent, for instance, the occupancy of each link. In real networks however it may be advantageous not only to obtain the lowest-cost tree but also to obtain the tree with the minimum number of arcs, in order that multipoint-to-multipoint virtual connections might be implemented with the minimum of network resources. This problem can be considered as a bicriteria Steiner tree problem for which a tabu search resolution approach is herein proposed and evaluated. This new approach leads to better results than the obtained by other heuristics presented earlier to solve the same problem. |

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.
