流量整形对QoS(quality of service)控制有着重要的影响.总结并优化了最近几年发展起来的能够深刻透视计算机网络业务流控制问题的网络演算技术,采用网络演算技术建立了包括贪婪无损失整形器、无缓冲区整形器及固定缓冲区长度整形器的一般性模型,获得了3种整形器的输入/输出特性以及整形器可提高QoS控制机制的效率等结果.
Traffic shaping has an important influence on the quality of service (QoS) control.This paper summarizes and optimizes the network calculus which has been developed in recent years to profoundly grasp the traffic control of computer networks, and uses the network calculus to build a network including the greedy lossless shaping A general model of bufferless shaper and fixed buffer length shaper obtains the input / output characteristics of the three shapers as well as the shaper’s ability to improve the efficiency of the QoS control mechanism.
