Abstract | The fast-developing services in internet pose challenges to the efficient transmission of various types of data, so an effective packet scheduling scheme is needed to meet the Qos constraints of heterogeneous services. In this article, the priority-queuing model is used to study the performances of various strategies based on delay sensitivity and packets length. And the non-preemptive short-packet-first strategy is proved to result in the minimization of overall delay. With different strategies for delay-sensitive and non-delay-sensitive services, an optimal priority-queuing model for the scheduling of multiple internet services is proposed based on the above conclusions. The results of simulation experiments in NS-2 proved the superiority of the model. The results also demonstrated the features of packets queuing under different traffic scenarios and the law of variation for such performance indices as packet delivery ratio, throughput and average delay, which can be used to design effective measures for performance optimization. |

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.
