| Abstract | We consider how a shared data network can effectively support connectivity-centric applications. Such applications include command dissemination and emergency alerts. These applications have low data rate requirements but depend critically on maximizing the fraction of messages sent that are delivered on time, which is called the connectivity of the network. Stresses that impair connectivity include low-quality wireless links, adversary action, network management errors, and high load. We argue that connectivity-centric applications require dedicated support at multiple layers. The network should provide two separate communications services, high-connectivity and high-capacity, with independent protocol stacks. The highconnectivity service trades resource consumption for improved connectivity at all layers and hence cannot be used for more than a small fraction of the overall traffic load. In addition to application data it carries control plane traffic critical to network operation and crisis recovery. The high-capacity service is a more traditional efficiency-optimized stack. We consider architectures for the high-connectivity service in both tactical wireless and core fiber networks. Within the overall architecture, we investigate in more detail path-diversity mechanisms for overcoming connectivity failures, and network segmentation to mitigate the effect of cyber attacks on the control plane. |

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.
