| Abstract | Group subscription is a useful mechanism for multicastcongestion control: RLM, RLC, FLID-DL, and WEBRC form a promisingline of multi-group protocols where receivers provide no feedbackto the sender but control congestion via group membershipregulation. Unfortunately, the group subscription mechanism alsooffers receivers an opportunity to elicit self-beneficial bandwidthallocations. In particular, a misbehaving receiver canignoreguidelines for group subscription and choose an unfairly highsubscription level in a multi-group multicast session. This poses aserious threat to fairness of bandwidth allocation. In this paper,we present the first solution for the problem of inflatedsubscription. Our design guards access to multicast groups withdynamic keys and consists of two independent components: DELTA(Distribution of ELigibility To Access) -- a novel method forin-band distribution of group keys to receivers that are eligibleto access the groups according to the congestion control protocol,and SIGMA (Secure Internet Group Management Architecture) -- ageneric architecture for key-based group access at edgerouters. |

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.
