| Abstract | We present a structured P2P system called Donuts, which exploits proximity, achieves load balance, and supports range query. The motivation is that range query incurs many overlay contiguous traverses, so making overlay neighbors physically nearby can significantly reduce communication costs. However, building a proximity-aware network may compromise load balance, as efficient load balance requires flexibility of node placement so that a lightly loaded node can leave its position to join beside a heavily loaded node to share its load. To resolve the conflict, we introduce a new concept - grouping. The idea is to cluster physically nearby nodes into several overlay sections to increase the flexibility of proximity join, routing, and load balancing while maintaining key ranges in neighboring nodes adjacent. Moreover, grouping can improve search efficiency by taking advantage of cache. It can also increase fault tolerance, especially to local catastrophes. In the following we introduce Donuts by starting from a simple model and gradually moving into a refined and sophisticated one. |

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.
