| Abstract | We consider the problem of establishing reliable multicast connections across a communication network. Our goal is to provide instantaneous recovery from single edge failures. With instantaneous recovery, all destination nodes can decode the packets sent by the source node even if one of the edges in the network fails, without the need of retransmission or rerouting. We build on the novel technique of network coding that offers significant advantages over standard solutions such as disjoint path routing and diversity coding. We begin by focusing on the case in which all network edges have equal capacity. For this case we present a network coding algorithm that constructs a robust network code over a small field. The algorithm takes advantage of special properties of the Maximum Rank Distance codes. Second, we consider a case of non-uniform edge capacities. We show that for the special case in which a small number of packets need to be transmitted from the source to destination nodes, special combinatorial properties of minimum coding networks can be exploited for constructing efficient robust network codes. |

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.
