Abstract Quality of Service (QoS) and Traffic Engineering (TE) capabilities are two important techniques in today’s networks for supporting real-time applications. Multi Protocol Label Switching (MPLS) plays an important part in IP networks for providing QoS and TE features. A general method to configure network based on MPLS is firstly introduced, then, a method to allocate network resource based on constraints at the DiffServ domain in IP network is proposed. The mathematical model and simulation of the method is given too. The simulation results show that the proposed method can balance the network load while the increase of the network cost is little.
