An Approach for Per-flow QoS Based on MPLS
一种基于MPLS保证每流服务质量的方法

Mechanisms of guarantee QoS currently are analyzed in this paper.Because MPLS only support of Differentiated Services(DiffServ),the solution is proposed by introducing dynamic packet state to MPLS network.By encapsulating state information in an extra label of MPLS packet,per-flow QoS is guaranteed without state maintained in core network.The architecture,data plane and control plane are illuminated.Finally,simulation results are given and the approach is testified.
