| Abstract | A self-stabilizing protocol is one that can continue to operate correctly after arbitrary corruption of protocol state variables and the injection of arbitrary messages. Self-stabilizing protocols are extremely robust and can be simpler than other protocols (because they use a uniform mechanism to deal with a large number of possible faults). We demonstrate these advantages by modifying the Fiber Distributed Data Interface Media Access Control (FDDI MAC), a widely used token-ring protocol, to make it self-stabilizing. Our modifications are simple: the major step is to add a token rotation counter and a phase bit that are carried in all messages. Not only is our modified protocol more robust (for example, our protocol recovers from multiple tokens in less than 5.75 ms, while the existing MAC might never recover), but it also recovers from lost tokens more quickly (0-0.36 ms versus 2.5-4.1 ms). We describe the modest changes made to the existing MAC state machine. |

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.
