| Abstract | In today's Internet with its multiple services, there is a growing need to provide quality of service (QoS) guarantees tailored to specific services rather than the best-effort QoS that is currently provided. One of the most important mechanisms for providing QoS guarantees is QoS routing. However, the main drawback to the use of QoS routing algorithms is their inability to scale well to large networks. This is particularly problematic in the Internet where the number of nodes (switches, routers, terminals) is growing exponentially with time. One solution to deal with this scalability problem is to divide a network into manageable blocks (sub-systems) and this is known as network partitioning. This paper focuses on a review of the so called stochastic partitioning methods that dynamically change a network partition according to the traffic patterns in the network in order to minimise an objective function that reflects the computational effort involved in the underlying routing algorithms used in the network. Such methods therefore exploit the interactions between the network topology, the traffic flows and the routing which are not collectively considered by other forms of partitioning. The review suggests that a method called Clique Stochastic Partitioning looks to be the most promising and this is examined further in the paper. A recommendation of the review is that future large networks, such as the Internet, should be designed to exhibit completely connected sub-structures in their topologies (called cliques). Then stochastic partitioning can be used to scale any routing algorithms so that the computational effort remains bounded to a manageable value as the number of network nodes grows. |

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.
