| Abstract | Nowadays a big effort is spent to reduce the Internet energy consumption. Actual Internet topologies have space to power off some links and devices to reduce the energy consumed in off-peak periods still guaranteeing connectivity among terminals. In this work we leverage the algebraic connectivity of the graph modeling an ISP network in order to define the ESACON (Energy Saving based on Algebraic CONnectivity) algorithm. We then consider the network connectivity as a first target performance to be assured. To this aim we identify a metric based on the algebraic connectivity that, on one side, allows to switch off several links with the consequent significant energy saving and, on the other side, still preserves network connectivity and network performance for efficiently supporting the Internet traffic. We find that ESACON achieves better performance with respect to similar topology-aware approaches; moreover ESACON performance are comparable with ones of a complex traffic-aware solution. |

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.
