| Abstract | Although the reduced load approximation technique has been extensively applied to flat networks, the feasibility of applying it to hierarchical network model has seldom been described. However, hierarchical routing is essential for large networks, such as the Internet inter/intra-domain routing hierarchy and the PNNI standard. Furthermore, most of research focused on the performance evaluation with fixed routing. Hence, this paper proposes an efficient and accurate analytical model for evaluating the performance of adaptive hierarchical networks with multiple classes of traffic. The evaluation model is based on decomposing a hierarchical route into several analytic hierarchical segments, therefore the blocking of the hierarchical path can be computed from these segments blocking. Numerical results indicate that the proposed adaptive hierarchical reduced load approximation yields quite accurate blocking probabilities as compared to that of simulation results. We also investigate the speed of the convergence rate of the reduced load approximation analysis in both of OD pair level and alternative hierarchical path level. |

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.
