| Abstract | An architecture style defines a commonly occurring pattern of the structural organization of components and connectors such that the impact of the pattern on the different non functional attributes is known. It is possible to make a qualitative assessment of whether a specific style is conducive to the nonfunctional attribute of performance based on the knowledge and experience in the use of the style. It is necessary however, that such a qualitative judgment be substantiated by a quantitative estimate obtained using a systematic performance analysis approach, since architecture styles are likely to be used in domains where application performance will play a critical role in ensuring its widespread use. Recognizing this need, several research efforts have focused on the development of quantitative performance analysis approaches for general purpose software architectures as well as for architecture styles. A notable drawback of the existing approaches is that they do not consider failures of components and connectors and hence provide optimistic performance estimates. In this paper we present a performability analysis approach for a pipeline architecture style which accounts for unreliable components. The performance estimate provided by the proposed approach is more realistic than what can be provided by the prevalent approaches. We illustrate the potential of the approach with an industrial case study of a document analysis system. |

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.
