【摘要】 为保证混合业务中流业务较低的丢包率和中断率,提出了一种基于二维效用函数的调度算法.仿真结果表明,提出的方法对于丢包率和中断率的服务质量保证能力,均优于修正的最大加权时延优先算法和指数正比公平算法等仅以排队时延为优化目标的混合业务调度算法.更多还原

【Abstract】 A scheduling algorithm based on the two dimensional utility function is proposed to guarantee the packet drop ratio and play-out outage ratio of streaming application in the mixed service scenario.The simulation results show that guarantee capability for the drop and play-out outage ratio of the proposed scheme outperforms the modified-largest weighted delay first algorithm and exponent proportional fair algorithm,which only take the head-of-line delay into consideration.更多还原
