Abstract | In this paper, we present an analytical tool called RETINA for analyzing real-time constraints in complex networks with stochastic traffic. RETINA is based on a statistical method called real-time queueing theory and can predict the fraction of late tasks in networks of queues given traffic conditions and queue protocol specifications. Upon submitting a profile of the network structure and data flow descriptions, the user is able to query certain performance metrics. Currently RETINA supports two types of real-time scheduling algorithms (EDF and FIFO) and three types of performance queries: the deadline miss rate of a designated flow, the minimum feasible deadline for a particular flow, and whether all QoS requirements of all flows met when a new flow is added. Simulation results show excellent agreement with the results predicted by our tool. RETINA has made it possible to analyze larger and more realistic networks and can be used to address network design tradeoffs. This use of RETINA to identify and quantify network bottlenecks is presented in the paper. |

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.
