| Abstract | This paper tackles the issue of optimizing the transport of video over packet networks with respect to both resource utilization and user perceived quality. Previous work showed that the quality of service requirements of multimedia applications can be satisfied by pipeline forwarding of packets. However, the current Internet is not based on such technology and its incremental introduction raises questions on how to handle video packets generated by pipeline forwarding unaware sources at the interface between a subnetwork deploying conventional packet scheduling techniques and one implementing pipeline forwarding. This work proposes to use the perceptual importance of the carried video samples to determine which packets shall be transferred with pipeline forwarding - thus receiving deterministic service - and which with a traditional, e.g., best effort or differentiated, service. Simulation results with the first implemented variants of this solution are presented. |

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.
