    Abstract:

    Differentiated services (DiffServ) is a scalable architecture for supporting quality of services (QoS), and video multicast is the application which needs network to support QoS guarantee. To accommodate to heterogeneous network and host, it is a good idea to transmit video in a few layers. The paper proposes LVMM (layered video multicast meter) and LVMF (layered video multicast forwarder) algorithms for distribution of the layered video multicast in DiffServ networks. The method needs only one multicast address and its validity is verified using ns-2 simulator.
