| Abstract | In this paper we present a method for optimal planning of bidirectional optical packet-switched rings, with synchronized work of ring stations and an out-of-band control channel. The network stations are equipped with tunable transmitters and fixed single-wavelength receivers that can be shared by different destinations and without a limit on their number per destination. Optimal planning method that is proposed here is based on linear programming, and provides an optimal network design with minimum transportation cost per network link and receiver, for the preferred method of traffic protection. We considered 1+1 protection (“premium”), which consist in doubling the capacity of each operational connection in the ring and 1:N protection (“regular”), in which the protection capacity is shared between multiple connections, as it is not supposed to be used until an unwanted event, i.e., a failure in the network. Enabling protection in such packet ring is a novel problem and here is solved for the first time, to the best authors' knowledge. By detailed simulations we studied the impact of different protection models on the cost of the network and its configuration, and the mutual interaction between protection methods and their effectiveness. The results suggest that the cost of premium protection is up to 40 % higher than the price of regular protection, and even up to 60 % higher than the cost of the network without any protection. |

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.
