| Abstract | Data center network (DCN), a type of network featuring low delays and high bandwidths, exchanges information rapidly through high-performance network switches. Currently, DCN provides various distributed services to satisfy user requirements. However, the size of buffers in the switches of DCNs is limited, thus causing throughput collapse when transmission control protocol (TCP) is used for multiple-to-one transmissions. Dropped packets result in additional retransmission costs and cause a substantial decrease in the efficient use of network bandwidths. Such a decrease in network performance is called a TCP incast problem. Previous studies have typically focused on modifying the original TCP or increasing additional switch hardware costs; rarely have studies focused on the existing DCN environments. Therefore, this study proposes using a cross-layer flow schedule with dynamical grouping (CLFS-DG) scheme to reduce the effect of TCP incast in DCNs. In CLSFDG, data transmission schedules are organized by a receiver using application-level information. Multiple data flows are then grouped for simultaneously transmission to improve TCP throughput and satisfy deadline requirements. The simulation result indicated that CLFS-DG can effectively prevent TCP incast occurrence and ensure the quality of service in the DCN. |

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.
