An Improved End-to-End Mix QoS Architecture

On the basis of analyzing briefly the advantages and disadvantages of Several QoS architectures,this paper combines Intserv/RSVP,Diffserv and MPLS with each other.Then,an improved end-to-end mix QoS architecture is established and its concrete implementation of Differentiated Services is provided,it mainly studies some problems in the implementation of the core nework and various types of service mapping.The proposed arthitecture possesses good expansibilities and robustnesses in Differentiated Services meanwhile providing end-to-end QoS guarantee.
