| Abstract | The transport traffic in WDM optical networks are provided to the networks customers in the form of lightpath via virtual topology reconfiguration(VTR), thus the algorithm to perform such an VTR has crucial impact on the resource usage efficiency. This paper proposes the routing algorithm of the Virtual Topology Reconfiguration based on the Genetic Algorithm (VTR-GA) for static traffic in the IP/WDM optical networks and develops an integer linear programming (ILP) model to solve the VTR problem. The proposed algorithm procedure and key issues, including the coding, initial population, fitness, crossover and variation within such an algorithm, are addressed. Its effectiveness in the resource utility has been verified by comparing the results from the proposed algorithm with those of both running CPLEX under the small-size network and the heuristic algorithms used formerly on the NSFnet. |

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.
