| Abstract | Given a fixed network infrastructure, i.e. a set of multicast sources and their corresponding receivers, we investigate the problem of constructing multicast sessions that maximize network utilization for all sources involved, under a fairness constraint. This is done by ensuring that multicast session construction protocols uniformly distribute multicast traffic over all links. In most standard IP multicast protocols (e.g., PIM), a single multicast tree is constructed for each multicast session and all data packets corresponding to a session are multicast on the same tree. A key observation in this paper is that distributing multicast traffic for a session over multiple multicast trees can dramatically increase the load balance and improve network utilization. In fact, our simulations indicate that merely using a few multicast trees per session can improve the common throughput of all sessions by a factor of up to two. We devise a standard compliant, distributed protocol which we call load balanced and cooperative multicast or LBCM to efficiently construct multiple multicast trees for each multicast group. We show how LBCM may be implemented on top of standard multicast protocols to improve network utilization in currently deployed systems. |

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.
