| Abstract | In this paper, using an autonomous and distributed approach, we aim at realizing a control mechanism, which is scalable in terms of the network size, for joint optimization of the multi-path routing and bandwidth allocation (MRBA). Multi-path routing is to determine multiple paths from the source node to the sink node such that the traffic demand by the source node can be successfully transferred to the sink node as well as the total network cost can be minimized. Bandwidth allocation is to decide the amount of bandwidth assigned to the flow at every link along multi-paths from the source node to the sink node, which are chosen by the multi-path routing. In this paper, we propose a distributed and scalable flow control mechanism called DFC-BP (Distributed Flow Control with Backward Propagation), which simultaneously solves multi-path routing and bandwidth allocation. DFC-BP is an autonomous and decentralized hop-by-hop flow control mechanism which can minimize the total network cost utilizing the backward propagation from downstream nodes to upstream nodes. We also investigate the effectiveness of DFC-BP in terms of efficiency, transient performance, adaptability, and parameter sensitivity through simulation experiments. Our findings include that the total network cost realized by DFC-BP is comparable to that by a centralized heuristic algorithm, and that DFC-BP quickly adapts to the occurrence of multiple link failures. |

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.
