QoS Model of Next Generation Network Based on MPLS

Abstract

Several QoS technologies are presented,one single technology can not solve the QoS problem perfectly.A new QoS model is brought forward,which integrates MPLS traffic engineering,DiffServ and IntServ.Design philosophy and implementation technique of this model are brought forward.Simulations about this model in NS2 are done.Compared with MPLS network,network delay is shortened and packets loss rate is decreased by 20% in proposed model.
