| Abstract | The current Internet is facing many challenges to accommodate the growing demands of cloud computing. Software-defined networking (SDN) is an emerging paradigm, proposed to be used in this context in order to investigate these issues. SDN virtualises network functions, reducing the amount of hardware and allowing to control data centres through software and programs. With SDN, it is possible to build the future Internet and solve the current issues. SDN assures the programmability of the network components and the development of new routing and forwarding approaches without changing the hardware components. However, the transition from traditional Internet protocol (IP) networks to full SDN networks is associated with many challenges in a short term as it requires from network operators a costly investment on new networking equipments. So, fulfilling full SDN architectures must be incrementally introduced in conventional IP networks. This study presents a performance study of a hybrid IP/SDN network, under NS-3, using Fat Tree, BCube and Three-tier data centre network (DCN) architectures, compared to conventional IP. Simulation results show that using a hybrid IP/SDN network enhances the performance of DCN architectures by providing an efficient communication and minimising the energy consumption. |

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.
