Abstract | Until recently, the problem of how to design survivable optical networks under single link failure has been studied quite extensively. However, the study on the design of optical networks for single node failure has been rarely discussed. This paper proposes 3 methods to reconfigure multicast traffic in WDM network for single node failure based on integer linear programming (ILP) technique by reconfiguration of entire network, reconfiguration of traffic traversing through failure node and reconfiguration of traffic adjacent to failure node. The last two methods, we used node-disjoint share protection path between primary path and backup path to reconfigure multicast traffic. We used multicast routing and wavelength assignment (MC-RWA) namely, light-tree (LT) and virtual light-tree (VLT) to design multicast traffic in WDM network for a single node failure. The objective of this paper is to design WDM network which supports multicast traffic for a single node failure in order to minimize fiber for survival network, given a static multicast traffic set, the number of wavelength per fiber can support and the network design approach (LT and VLT). |

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.
