| Abstract | Providing differentiated quality-of-protection (QoP) for surviving single-link failures in WDM mesh networks has been extensively studied in recent years. This paper investigates the problem of providing differentiated QoP for surviving arbitrary double-link failures by allowing a connection request to choose from several QoP classes. In this paper, we propose to use three classes, i.e., single shared-path protection (SSPP), single dedicated-path protection (SDPP), and double shared-path protection (DSPP) to provide differentiated QoP. We present two differentiated QoP schemes. Scheme 1 (conventional differentiated QoP) is a natural extension of conventional differentiated QoP for surviving single-link failures, which uses SDPP, SSPP, and SDPP separately to satisfy different QoP requirements. Scheme 2 (shared differentiated QoP) tries to share backup resources between SSPP and SDPP. Simulation results show that our proposed architecture of QoP can satisfy different QoP requirements for surviving double-link failures by making a balance between blocking probability and average QoP. Analytical and numerical results indicate that the proposed differentiated QoP scheme 2 are more efficient in improving not only blocking probability but also average QoP. |

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.
