| Abstract | The ever-increasing requirements for performance, flexibility, and robustness are imposing a severe strain on the Internet's stagnated architecture. Network virtualization arises as a potential solution for improving the current situation by letting multiple networks with different requirements, architectures and protocols to coexist and share the same infrastructure in an independent way. These advantages are of great interest for network operators. This paper presents a virtualization platform that enables the creation, discovery, monitoring and management of virtual networks. It then concentrates on the proposal of a distributed discovery algorithm that is able to discover both physical and virtual network topologies. This algorithm uses the concepts of level 2 multicast and spanning tree to decrease the overhead related to the exchange of discovery messages between the nodes. The simulation results show that, when compared to gossip based discovery algorithms, the performance of our approach is significantly increased, up to an improvement in exchanged messages of three orders of magnitude, when considering physical networks with 500 nodes. Experimental results have shown that distributed approaches also introduce significant improvements when compared with centralized approaches. |

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.
