| Abstract | Communication networks typically provide a basic best-effort service category, in which resources are shared by concurrent users. As no QoS guarantees are provided, a user will submit to best-effort service only if the expected QoS meets some minimal, user-specific, requirements. This results in an inherent conflict of interest among users, which we capture through a dynamic noncooperative game model and investigate its structure and properties. Specifically, we study the operating points of such systems, i.e., their Nash equilibria. First, we investigate the optimal user strategies, which involve a prediction of the evolving system state, and show that they are of the threshold type. We then establish that a Nash equilibrium point exists and is unique. An algorithmic scheme for computing the Nash equilibrium is provided. In practice, rather than making complex predictions, users typically employ simple decision rules, based on what they learn by experience. Interestingly, it can be shown that the Nash equilibrium of the considered system is a stationary point of such learning schemes. Moreover, we demonstrate that the decisions of users which employ such schemes converge to the Nash equilibrium. Finally, we discuss the implications of the study on network design and management. |

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.
