%X For providing per flow QoS guarantee in MPLS networks, this paper proposed a supply side DiffServ marking method based on network dynamic. Before entering the network, individual stream requested a per-hop admission control along the delivery path and installs flow-specific reservation on ingress router as flow state. Marked stream packets into reserved/unreserved profile on ingress node according the flow reservation, and had a differentiated processing based on PHB at later nodes. It marked individual stream as its reservation, maped flow-based reservation into quantitative behavior-based marks, and finally combined IntServ and DiffServ. This method, on the one hand, avoids collision and provides quantitative per flow QoS guarantee, on the other hand, keeps DiffServ scalable without any per flow management on core routers.
