| Abstract | We evaluate and compare the performance of three P2P streaming systems that are capable of streaming live video on the Internet by testing them on a carefully controlled, traffic-shaped network test-bed. We first describe the construction of the test-bed based upon Internet measurements between geographically distributed hosts. Then, we present a methodology for evaluating these P2P video streaming systems by performing video quality and network usage analysis from the log information obtained via running these systems on the test-bed. Our methodology to assess P2P live video streaming systems comprises analyzing the objective quality of the received video, waiting time to receive the first data byte, and several network usage measures such as P2P protocol overhead, load on the server due to the inefficiencies of the P2P overlay, and measurements of the number of bytes exchanged between the peers. It is essential that every peer buffers packets for some time before playing out the video in order to ensure good quality. We report the time that the user has to wait before he can see the video playing. These measurements not only gauge the performance of currently available P2P streaming systems but also highlight desired improvements in current P2P video streaming systems. |

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.
