摘　　要：为实现对网络新兴业务的QoS保障支持,以及根据网络状态感知实施动态QoS保障,提出了一种基于流视图的动态QoS保障机制。该机制的基本思想是根据网络的实时流量分布即流视图,在同类型流量分布密集的区间为该类型数据流提供QoS保障。这种保障机制能够合理分配网络资源,使得各种类型的数据流能够以"各取所需"的方式得到QoS保障,同时其自适应性和可扩展性使得该机制能够满足网络新兴业务的QoS保障需求。仿真实验表明,基于流视图的动态QoS保障机制能够动态适应不断变化的网络环境,并为各种类型的网络流提供相应的QoS保障服务。A dynamic QoS guaranteed mechanism based on flow view is proposed in order to realize the QoS support for new services and guarantee the network QoS dynamically according to the network status. The basic idea is to provide QoS guarantee for the network flows of the same type in the intensively distributed interval calculated based on the real-time flow distribution, namely the flow view. Network resources can be allocated rationally and flows can get QoS guarantee according to their needs. Experiment results show that the flow-view-based QoS mechanism can dynamically a- dapt itself to the changing network environment and provide QoS guarantee for different types of net- work flows.
