Mobile Network QOS Algorithm Analysis And Tentative Design Based On Differentiated Service

Along with the high-speed development of the Internet and wireless communication technologies,mobile information society is rapidly evolving,Getting information and services is the needs of your users conveniently,quickly,anytime,anywhere,but also the characteristics of mobile information society。The mobile Internet is the infrastructure to building the mobile information society,and it should provide the safe,reliable and providing corresponding quality of service(QOS)performance information transmission services。However,because the topological structure and resources of mobile Infernet are in a dynamic changes,providing corresponding quality of service(QOS)performance is a very challenging task。So,QOS of the mobile Internet becomes one of the key technologies。This paper first studies and discusses the QOS architecture in the fixed network and in-depth analyses the Diffserv,IntServ and MPLS how to support the QOS question in the mobile environments。Then,the paper proposes the mobile Internet QOS architecture based on the MPLS and Intserv which are based on Diffserv。, simultaneously,analyses a few algorithms in the application of the Differv in these two architectures。Finally,the paper proves the bandwidth,Throughput technical target and so on of the stability and reliability of the proposal through NS2 simulation experiment, thus achieves the purpose of raising mobile Internet quality of service。...
