A novel QoS guaranteed mechanism for multicast traffic controls in the home network

The home network has been revitalized due to the emergence of the broadband convergence network and the inter-networked home devices. The home gateway, which can be identified as a major component of the home network, enables to interconnect various home devices to one another as well as the Internet. Also, as the number of multimedia services, which requires high bandwidth and real-time support, increase users demand on the guaranteed quality for the services in the home network. In order to satisfy the user requirements, the Internet Service Providers (ISPs) have been providing a QoS mechanism for the home network services. However, the ISPs can not guarantee the end-to-end QoS from source to destination due to the misleading fact that the home gateway is recognized as an end terminal in terms of the ISP's viewpoint. Thus the QoS guaranteed mechanism for the remaining path, from the home gateway to the home devices, should be considered within the home network domain. In this paper, we propose a novel mechanism to guarantee the home network QoS for the services based on multicast traffics such as the IPTV or multilateral video conferencing. In order to meet the user requirements on the home network QoS, the proposed mechanism manages resources, classifies the traffic and also executes call admission controls for the service requested in the home network by utilizing the IGMP snooping scheme. Through the experiments of implementing the multicast based IPTV services, we will verify the proposed mechanism.
