| Abstract | In order to achieve guaranteed services, we need to negotiate network resources providing the required quality of services(QoS). For this reason, the common set-up process of servicesession is divided into three phases. At first, the application specifies its QoS requirements, then, the QoS parameters at IP level and MAC level are successively specified and finally the network applies the negotiated QoS configuration. In this paper, we propose to negotiate at the same time the QoS parameters at both levels. An optimization of this approach has also been discussed. This optimization focuses on distributing negotiated QoS parameters between several entities located in different hierarchical levels. The assignment of parameters is dynamically configured. Therefore, this paper proposes a performance model to compare the new combined-distributed negotiation process with the negotiation processes applied in UMTS Release 5 (R5) [4]during session establishment. Numerical results show that the proposed approach is more scalable on the network side than the UMTS approach. |

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.
