摘要 区分服务是一种可扩展的服务质量支撑框架,视频组播是对服务质量有较高要求的应用.为了满足端系统的异构性要求,对视频进行分层传输是比较好的方法.研究了使用区服务中的确保服务进行分层视频组播传输的方法,提出了LVMM(layeredvideomulticastmeter)测量算法和LVMF(layeredvideomulticastforwarder)转发算法.该方法只需要一个组播地址,其有效性通过ns-2模拟器进行了验证. 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.
