| Abstract | The stable-paths problem is an abstraction of the basic functionality of the Internet's BGP (border gateway protocol) routing protocol. This abstraction has received considerable attention, due to the instabilities observed in BGP. In this abstraction, each node informs its neighboring nodes of its current path to the destination node. From the paths received from its neighbors, each node chooses the best path according to some locally chosen routing policy. However, since routing policies are chosen locally, conflicts may occur between nodes, resulting in unstable behavior. Current solutions either require expensive path histories, or prevent nodes from locally choosing their routing policy. We present a solution with small overhead, and furthermore, each node has the freedom to choose any routing policy. However, to avoid instabilities, the possibility of divergence is measured using an efficient cost metric exchanged between nodes. If the cost metric indicates that divergence is occurring, steps are taken to ensure convergence. |

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.
