| Abstract | Harmony is a network resource brokering system that provides co-allocation of heterogeneous (optical) network resources in multi-domain and multi-technology environments with advance reservation functionalities. This system is one of the outcomes of the Phosphorus EC FP6 research project. The Harmony system architecture has evolved from a first proof-of-concept, centralized network service plane (NSP) to a distributed NSP model; passing through a mid-term, multi-level hierarchical model. This paper addresses key performance and scalability topics of the Harmony system, analyzing its functional architecture under different scenarios, and given different request distribution patterns. The study analyzes and evaluates whether the system can scale to scenarios that accept more requests per second or control more administrative domains. Thus, analysis results are discussed in order to determine why the distributed architecture with flexible, in time and bandwidth, advance reservation functionalities has better performance, scalability and convergence when increasing the service plane entities and their relationships. |

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.
