宽带无线IP系统中基于区分服务的QoS实现策略

Quality of Service in Wideband Wireless IP Network Based on Differentiated Services Architecture

讨论了在宽带无线IP系统中实现QoS的问题。提出了一个基于区分服务(DiffServ)的QoS框架,并针对无线链路上的高误码率、窄带宽、性能变化剧烈、用户移动性等特点,对DiffServ进行了加强,并提供了一种针对业务类型的用户接入控制机制。仿真结果显示了该QoS框架的性能。

This paper considers the problem of providing QoS in wideband wireless IP network.This paper proposes an architecture base d on DiffServ framework.The framewo rk has been modified to handle several wireless specific features including high loss rate,low wirele ss bandwidth,fast -variety of capab ili-ty and mobility.This paper provides an admission control policy based on type of services.Simulation re-sults show the performance of this Qo S architecture.
