摘要 现代数据中心网络中的应用执行多个复杂的任务,而小任务和大任务公平共享带宽不利于减小任务平均完成时间。为此,提出一种任务大小感知的拥塞控制协议,依据任务大小因子和拖尾因子来调节发送速率。实验结果表明,与DCTCP、L2DCT、Baraat协议相比,该协议可减少网络应用任务的平均完成时间。 Applications perform a number of complex tasks in modern Data Center Network(DCN)?Small tasks and large tasks share bandwidth fairly is not conducive to reducing the average task completion time.Therefore,this paper presents a congestion control protocol for task size perception.The transmission rate is adjusted according to the task size factor and the trailing factor.Experimental results show that,compared with DCTCP,L2DCT,Baraat protocols,this method can reduce the average time of task application in the network.
