| Abstract | In this paper, we present a software framework for adding fault-tolerance to existing finite-state programs. The input to our framework is a fault-intolerant program and a class of faults that perturbs the program. The output of our framework is a fault-tolerant version of the input program. Our framework provides (1) the first automated tool for the synthesis of fault-tolerant distributed programs, and (2) an extensible platform for researchers to develop a repository of heuristics that deal with the complexity of adding fault-tolerance to distributed programs. We also present a set of heuristics for polynomial-time addition of fault-tolerance to distributed programs. We have used this framework for automated synthesis of several fault-tolerant programs including a simplified version of an aircraft altitude switch, token ring, Byzantine agreement, and agreement in the presence of Byzantine and fail-stop faults. These examples illustrate that our framework can be used for synthesizing programs that tolerate different types of faults (process restarts, Byzantine and fail-stop) and programs that are subject to multiple faults (Byzantine and fail-stop) simultaneously. We have found our framework to be highly useful for pedagogical purposes, especially for teaching concepts of fault-tolerance, automatic program transformation, and the effect of heuristics. |

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.
