| Abstract | Aggregated multicast methods have been proposed in order to reduce the size of routing tables in routers for multicast communications, where plural multicast sessions share a single multicast tree called Shared-Tree. STA (Scalable-Tree-Aggregation) method has been proposed as a Shared-Tree selection method, where a minimum size Shared-Tree has been selected among Shared-Trees which contain all destination nodes of a multicast session. In the STA method, the selected Shared-Tree sometimes contains invalid destination nodes for the multicast session and causes the unnecessary traffic load. In this paper, we proposed a novel Shared-Tree selection method which makes it possible to select smaller size Shared-Tree compared with the multicast session by a grafting method. By the grafting method, destination nodes not involved in the selected Shared-Tree can be connected to the Shared-Tree. We can expand the search range of Shared-Trees by the grafting method and select a Shared-Tree, destination nodes of which overlap those of the multicast session as many as possible. In our proposed selection method, Shared-Trees are selected by the measurement of overlapping degree, which indicates how many destination nodes in the multicast session overlap with those in Shared-Trees. Moreover, we introduce a replacement method for reducing the entry size of Shared-Trees. We evaluate our selection method by simulation experiments and show the effectiveness of our proposed method. |

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.
