| Abstract | Research on TCP performance relies either on simulation programs, which run on a single machine, or on the use of real testbeds, where different machines represent different network nodes and data exchange is made through physical network interfaces. This paper proposes a different solution, with the aim of taking the best of both the cited alternative options. The idea is to exploit the most advanced virtualization technologies to integrate the different devices of a real testbed in a single GNU/Linux physical machine. The Virtual Integrated TCP Testbed (VITT) presented in this paper is the practical realization of this concept. Several virtual machines, fully configurable from the host system, are connected through an emulated network, implemented by means of the software tools provided by the Virtual Distributed Ethernet (VDE) project. A simple web interface allows the user to configure the network layout, set the TCP parameters, launch the experiments and gather the results. VITT is built on the experience achieved by the authors in the design and use of a real distributed testbed (TATPA), from which VITT derives some software components. TATPA results proved essential to assess the present limits of the virtualization approach, i.e. the accuracy of results vs. network complexity. |

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.
