| Abstract | The paper proposes several clustering algorithms to explore the topology of the AS-graph. Using these algorithms, we are able to view the Internet topology, as encapsulated by the AS-graph, at three levels of abstraction: (1) a low-resolution view, which shows a coarse cluster cover of the whole AS-graph; (2) a mid-resolution view, showing the relationships between dense cores inside the coarse clusters; (3) a high-resolution view of individual high-density cores. Using these tools we discover that the Internet's central dense core is at least twice as large as what was previously reported. Attached to the central dense core, in what is known as the transit core, our clustering tools discovered several clusters, which we call the regional dense cores. Interestingly, these clusters are as dense as the central core itself. Our tools highlight the fact that the regional dense cores are mostly connected to the central dense core and less well connected among themselves. |

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.
