| Abstract | The objective of this study is to propose a new bufferless optical packet switching architecture in which thew converters, needed to solve output packet contentions, are used in two levels. The architecture is equipped with limited-range wavelength converters (LRWCs) at the first level and with shared and full-range wavelength converters (FRWCs) at the second level. In a WDM all optical network, in the absence of wavelength conversion ability, the signal is required to be on the same wavelength from hop to hop, which is referred to as the wavelength continuity constraint Studies show that network performance is greatly improved by using wavelength converters [1]. If a wavelength converter can convert a wavelength to any other wavelength in the optical system, it is called full range wavelength converter. However, this type of wavelength conversion is quite difficult and expensive to implement due to technological limitations [2]. In proposed architecture, limited numbers of FRWCs are shared at the output of optical packet switch, to make that more cost effective. Although a few number of FRWCs are used, it causes reduction of packet loss probability about 40%. |

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.
