| Abstract | Conventional multi-stage switches perform well in theory but degrade in application. The conventional traffic control to a flow corresponds to the destination module, so the flows destined to the same output module have bandwidth competition although they should not. The evaluation of conventional switches is only based on traffic patterns with these two features: the required bandwidth of all output ports is identical and no output is oversubscribed. Under their traffic patterns, bandwidth competition never happens. However, there exist other traffic patterns that they don't concern, in which the existed bandwidth competition will lead to degradation. We define this issue as Flow Interference (FI). To address it, we propose a philosophy that traffic control to a flow should correspond to its own destination output based on the global information. Based on this, we propose our switch architecture to solve FI using round-robin at all stages. Analysis and simulation results show that our multi-stage switch architecture can solve FI and achieve perfect performance, with O(1) computational complexity for the scheduling algorithm. |

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.
