| 定义了区分服务网络中AFPHB的公平性,指出对响应流和非响应流区别的不同只应针对其超出规范的流量,并且业务量的响应性的判定应根据其行为而不是仅靠协议类型.通过仿真验证标记器srTCM和trTCM以及8种映射机制是否能提供公平性.在DS网中,存在通过不区分流的响应性的标记算法可提供公平性的负荷范围,作者将其定义为公平区间,并对其参数配置进行了分析. |

| Abstract: |
| This paper defines the meaning of fairness more suitable for AF PHB in DS network. Besides, this paper argues that responsive and un responsive flows should be treated differently only to their out of profile traffic. In addition, traffic responsiveness should be identified by its behavior rather than simply by protocol. Moreover, two markers, srTCM and trTCM, with eight mapping schemes are examined by simulations to check whether they can provide fairness in DS networks. This paper also defines fairness area as the network load range where the DS network can provide fairness to responsive and un-responsive aggregate by marking without discriminating,and parameters configuration of the area is also given. |
