| Abstract | Third generation (3G) networks will provide support for high speed applications to its users in both the forward and reverse directions. In the forward direction, this is achieved by time sharing users over one or more high speed packet data channels. Users are scheduled based on their application needs as well as the mobile operator's objectives. On the reverse link, two options are possible for serving users, rate control and scheduling. Scheduling provides fine control of reverse link resources but at the expense of complexity and signaling overhead. Two forms of rate control are possible, common rate control and dedicated rate control. Dedicated rate control is similar in concept to scheduling, but is limited to one rate level change per user. In common rate control, each mobile independently determines its reverse link rate using load information that is broadcast by the base station on a periodic basis. The algorithm used by each mobile to determine its transmission rate should again be determined based on the needs of the application as well as the operator's overall objectives. One option is to be completely fair and provide all mobiles (as much as is physically possible) with identical transmission rates (i.e., the performance objective used for voice users). Another option is to allow mobiles to use rates based on their reverse link channel conditions (the proportionally fair performance objective used in the forward packet data channel). We compare the throughput and fairness of these two approaches. |

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.
