| Abstract | The requirements of multimedia streaming challenge the QoS (quality of service) capability on home networks, where typical construction is a hybrid Ethernet and WLAN (wireless LAN). This paper proposes a novel software solution, called layer 2.5 SoftMAC, to provide QoS on home network using commercial IEEE 802.11 wireless and Ethernet hardware. SoftMAC resides between 802.11/ Ethernet MAC layer and IP layer to coordinate the real-time (RT) and best-effort (BE) packets transmission among end-devices in home networks, i.e., no modification to wireless AP (access point) or Ethernet switch. To effectively support media streaming, it employs three key components: 1) admission control (AC) for regulating the load of RT traffic, 2) rate control (RC) that minimizes the impact of BE traffic on RT traffic, and 3) non-preemptive priority queueing (PQ) to provide high priority service to RT traffic. To evaluate the efficacy of SoftMAC, we conduct extensive simulations using the network simulator NS2. We also implement our proposed SoftMAC as a Windows network driver interface specification (NDIS) driver over network interface card (NIC) driver, and build a testbed to emulate hybrid home environment with 802.11 a/g and 100M Ethernet to test its performance on real system. Our evaluation and testing results demonstrate the effectiveness of SoftMAC. |

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.
