| Abstract | The P2P-based video-on-demand (P2P VoD) service has achieved tremendous success among Internet users, and attracted many researchers’ interest. Piece selection policy, peer selection policy and replica management policy are three important policies in P2P VoD systems. Although there has been some research work on the policy selection of the P2P VoD system, it still remains unknown that which policy composition is better for the system. Different from the existing research, we study the existing P2P VoD policies by using a simulation framework to understand the features as well as the performance of different policy compositions. The simulation results indicate that when the bandwidth and storage resources are limited in the P2P VoD system, the composition of the sequential piece selection policy, the cascading peer selection policy and the proportional replica management policy has the best performance among all the different policy compositions. However, when the bandwidth and storage resources are sufficient in the system, there will be little difference between different policies. To further understand such a system, we also explore the impact of resources on policies selection. Our simulation provides evidence that theoretically the P2P VoD system can work well without extra replica space as long as the bandwidth of the peers is large enough, but the extra storage space can help improve the performance of the system in practical scenarios where the peers’ bandwidth is limited. |

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.
