| Abstract | We propose MCA, a rate-based end-to-end multicast congestion avoidance scheme. Congestion avoidance is different from congestion control in the sense that our scheme detects and responds to network congestion without necessarily inducing packet loss. Our scheme is a single-rate scheme and operates end-to-end, i.e., it goes at the rate allowed by the worst congested receiver and does not expect packet marking or other support from intermediate bottlenecks. Congestion is detected autonomously at receivers using the concept of "accumulation" and simple thresholding techniques proposed in our previous unicast work. Congestion feedback to senders can be in the form of single-bit congestion indication (CIs) or as a multi-bit output rate measure. The feedback is sparse in the sense that at most one feedback is generated per measurement period (unlike multiple loss indications generated during packet loss). The source implements two key blocks: a filtering block to discriminate between competing feedback from receivers, and a congestion response block which implements a rate-increase/decrease policy. The two different feedback models (bit-based or explicit rate-based) leads to two different schemes: bit-based and explicit rate-based schemes. Simulation results show that both schemes avoid the drop-to-zero problem and are fair with unicast congestion avoidance schemes. |

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.
