| Abstract | The congestion avoidance technique for event builders with switching network technologies is a main issue. Traffic management of the data flow is an essential point to avoid the congestion. Global traffic control is one of the mechanisms to manage the traffic. It uses information of the switching network. Traffic shaping technique is another mechanism not to use them. QoS is one of the solutions to avoid this congestion, because it provides the bandwidth allocation in the network. A Gigabit Ethernet technology, which is a major in the high performance network, however, has no functionality of the QoS while ATM has the functionality of the QoS on a hardware level. Recently, IP-based QoS is intensively studied in computer science. On Gigabit Ethernet with the QoS, it will be expected to avoid the congestion of the event builder traffic. We used Alteon network interface card, which can handle large MTU called jumbo frame. Jumbo frame improves the transfer speed. We also used Linux-based PCs for measuring the performance. We chose several parameters such as device driver parameters, MTU, chipset for PC, bus width of PCI (64/32-bit) and so on, related to the performance. We found high performance chipset for PC and 64-bit PCI bus improved the transfer speed up to 990 Mbit/s with jumbo frame. We had the results that the overhead of the IP-based QoS is very small and the bandwidth allocation worked. |

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.
