| Abstract | Although EDF (Earliest Deadline First) algorithm has received extensive study during the past more than 40 years, only a few researchers have published their efforts on the bandwidth transfer between tasks. If current running tasks are compressed to free part of their occupied bandwidth to accommodate new requirements, such as a new task’s insertion, then a basic requirement of this operation is smoothness, that is, no deadline should be missed. Suppose current tasks are immediately compressed at the request time of the new task, in order to guarantee the smoothness, the new task may have to be released later than the request time. An interesting and challenging problem is to find the earliest smooth release time. In this paper, an algorithm to evaluate the earliest release time for single task’s insertion is presented and formally proved. To finish the algorithm, only the deadlines during the transition should be checked, and each of them needs to be checked at most once. A novel experimental approach is adopted and more than 4549320 different tests are implemented to verify the theorems in simulation. |

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.
