Abstract | A reconfigurable protection is extended in ASON survivability testbed SURBED, the performance and extra overhead are presented and also compared with several survivability techniques (1+1, shared mesh, rerouting, etc) in SURBED. Pre configured protection cycles (p-cycle) is a kind of preconfigured protection mechanism that can have mesh-like resource efficiency and ring-link protection speed. But under multi-region survivable network, the topology and resource information is not always available due to policy reasons or other else, so distributed approach with agent negotiation is attractable. As the dimensions of WDM optical network grows larger and larger, it tends to be a mesh structure. Based on SURBED, we take extensive simulation to investigate the performance of different signaling strategies by multi-region agent negotiations. Unlike previous work, we focus on the reconfiguring process rather than the switching over operation of control plane in ASON. The backbone is overlaid, in which most of devices are IP router networks. Routers are interconnected by fibers or SDH or WDM links. It is the same with non-reconfigured p-cycle, the reconfiguration need a criterion, and here we use the network real-time performance as a reconfiguration trigger to take actions on p-cycle reconfiguration. |

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.
