The integration of IP TE (traffic engineering) and DS (differentiated service) is a new method to enhance QoS (quality of service) guarantee in network. In this paper, based on analyzing the requirement of DS for TE, the integrating framework is constructed, a schedule method suitable to TE is put forward, as well as the principle and the method of partitioning and mapping. This method carries out traffic splitting according to table.not only distinguishes the priorities of packets forwarded in DS domain, but also guarantees the requirements for delay and disting uishes the priorities ofr delay and synchronization of data flow.
