QoSAF is divided into three layers: resource control layer, net-work service layer and business layer. QoS management is accomplished by interactivity of layers. In this ar-chitecture, mechanism of feedback control enhances the functions of resource management and system moni-toring. The principle of design and logical architecture of system is discussed in detail.展开更多
