| Abstract | The technology based on Wavelength Division Multiplexing (WDM) applied to optical networks has resolved the bandwidth waste in this kind of networks. WDM divides the bandwidth of an optical fiber in different wavelengths that can be used by electronic devices to send and receive data without bottlenecks. Another problem appears when the necessity of choice of the path and the wavelengths to interconnect a set of source-destination pairs comes up. This problem is known as Routing and Wavelength Assignment (RWA) and there are two types, depending on the demands: Static-RWA and Dynamic-RWA. In this paper we present a multiobjective evolutionary algorithm to solve this problem. We choose the Differential Evolution (DE), incorporating the concept of Pareto Tournament (DEPT). To determine the parameters of the algorithm, we used two real different topologies (the first is a topology from USA, NSF network; and the second is a topology from Japan, NTT network) and six sets of source-destination pairs for each topology, that is, a total of twelve instances. After all experiments, we can conclude that with this multiobjective evolutionary algorithm, we have obtained better results than the other approaches published in the literature. |

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.
