加性区分服务的动态PGPS(D-PGPS)实现

D-PGPS:A SOLUTION TO ADDITIVE DIFFERENTIATED SERVICES

IPv6网络的区分服务模型能够为各种应用提供不同的服务质量。在实现不同等级之间的服务差异时 ,研究者提出了不同的策略 ,其中具有代表性的有Ramanathan提出的按比例实现区分服务的算法[1 ,2 ] 。本文中 ,我们提出了加性区分服务的概念 ,设计了能提供加性区分服务的动态PGPS(D PGPS)算法 ;在NS 2仿真环境下 ,研究了该算法对各等级服务的延时效果。

The DiffServ-Model in IPv6 provides different qualities of service(QoS)for multifarious applications.Researchers have designed some algorithms to achieve the difference between relative levels.A representative among them is the proportional differentiated services proposed by Ramanathan [1,2].In this work,we proposed the Dynamic PGPS model to achieve the goal of additive differentiated services,which is a brand-new concept.We also have simulated D-PGPS's effect on delay differentiation in NS-2.[KH3/4D]
