| Abstract | The increasing amount of digital data generated by today's society asks for better storage solutions. This survey looks at a new generation of coding techniques designed specifically for the maintenance needs of networked distributed storage systems (NDSS), trying to reach the best compromise among storage space efficiency, fault-tolerance, and maintenance overheads. Four families of codes, namely, pyramid, hierarchical, regenerating and locally repairable codes such as self-repairing codes, along with a heuristic of cross-object coding to improve repairability in NDSS are presented at a high level. The code descriptions are accompanied with simple nexamples emphasizing the main ideas behind each of these code families. We discuss their pros and cons before concluding with a brief and preliminary comparison. This survey deliberately excludes technical details and does not contain an exhaustive list of code constructions. Instead, it provides an overview of the major novel code families in a manner easily accessible to a broad audience, by presenting the big picture of advances in coding techniques for maintenance of NDSS. |

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.
