| Abstract | Research in workflow management systems design references the mobile agent computing paradigm where agents have been shown to increase the total capacity of a workflow system through the decoupling of execution management from a statically designated workflow engine, although coordinating fault tolerance mechanisms has been shown to be a downside due to increased overall execution times. To address this issue, we develop a model for comparing the effects of two fault tolerance techniques: local and remote checkpointing. The model enables an examination of fault tolerance coordination impacts on execution time while concomitantly taking into account the dynamic nature of a workflow environment. A proposed use for the model includes providing for selecting and configuring agent-based fault tolerance approaches based on changes in environmental variables - an approach that allows the owners of a workflow management system to reap the scaling efficiency benefits of the mobile agent paradigm without being forced to make trade-offs in execution performance. |

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.
