| Abstract | Network virtualization is a new technology that aims at allowing multiple virtual networks (VNs) to coexist in the same equipment and to hide the heterogeneity of network infrastructure. The critical issue for a given infrastructure provider (InP), is how to provide customized and on demand resources for multiple service providers (SPs) with different Quality of Service (QoS) requirements. The should also fairly distribute the network physical resources, such as bandwidth of each physical link, buffer spaces, and processing cycles at each node. In this paper, we propose a new framework based on game theory, for both link and node dynamic allocation between multiple infrastructure providers (InPs) and service providers (SPs). Our approach focuses on provisioning and managing the physical resources in a virtualized network infrastructure. We propose a two-stage approach based on non-cooperative games. The first one is the resource negotiation game where the SP requests link and node resources from multiple InPs. The InP may reject the SP’s request when it can potentially cause network congestion. The second stage of the proposal concerns dynamic resource provisioning and consists of two non cooperative games; the node allocation game and the link allocation game. The objective of both games is to allocate physical resources for different isolated VNs that are sharing the same physical substrate network. In the node allocation game, the proportional share mechanism is used. Every SP assigns a weight and submits a bid to each physical node and thereafter it receives a share proportional to its bid. In the link allocation game we investigate the case when multiple SPs compete for a portion of the available physical network capacity. Simulation results show that the proposed approach achieves high resource utilization, improves the network performance, and fairly distributes the link and node resources between multiple SPs. |

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.
