| Abstract | Resolving contention in an efficient and cost-effective manner is a key issue in optical burst switched (OBS) networks. Although deflection routing has been identified as a cost-effective solution, its viability has been questioned. We propose an emission and discard priority (EDP) scheme to alleviate the shortcomings of deflection routing. The objective of this EDP scheme is to reduce the number of late packet arrivals due to burst deflections and to increase the efficiency of deflection routing with selective burst deflections. Through simulation, we compare the performance of deflection routing using the EDP scheme with a basic deflection routing scheme and a no-deflection scheme. Simulation results show that the deflection with EDP scheme has a higher throughput than the basic deflection scheme for loads L ges 0.7 and has a lower proportion of late packet arrivals than the deflection scheme at all loads. We also find that the deflection with EDP scheme has higher goodput than the basic deflection scheme for loads L ges 0.7 . Furthermore, the deflection with EDP scheme has greater efficiency than the deflection scheme in terms of goodput per deflection. |

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.
