| Abstract | Recently, FDDI (Fiber Distributed Data Interface) has come under pressure from switched Gigabit Ethernet in the enterprise backbone. In high-speed Gigabit Ethernet networks, traffic is expected to be highly bursty. In particular, whenever data flows from the high-speed link to the low-speed one, congestion commonly occurs. The Virtual-Connection Network (VCN) is a switch-based network capable of implementing cell-based connections, link-by-link flow-controlled connections, and single- or multi-destination virtual connections. Virtual connections described differ from the virtual channel in the ATM literature in that virtual connections have link-by-link flow control and can be multi-destination. VCN's support both connection-oriented and connectionless data link layer traffic. Therefore, the worst collision scenario in Ethernet CSMA/CD with virtual collision brings about end-to-end delay. The goal is to guarantee the performance with respect to bandwidth and latency for selected VCs with different propagation delay, To this end, we propose a classical proportional controller plus a Smith predictor to overcome instability accompanying increased round-trip delays as well as to avoid cell losses. The proposed control policy is illustrated by a simulation study. |

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.
