文中针对多路媒体流的调度问题,在分析经典的缓冲区反馈控制算法和按DTS调度算法基础上,提出了一种基于权重的调度算法,该算法对各路媒体流均动态分配权重,调度前比较各路媒体流的权重,每次选择权重最大的媒体流进行调度,它吸取了其它多路媒体流调度算法的优点,并充分考虑了多路媒体流调度的优先级问题。试验结果表明该算法是切实可行的和有效的。
In this paper, a scheduling algorithm based on weight is proposed based on analyzing the classical buffer feedback control algorithm and scheduling algorithm based on DTS. This algorithm allocates weights dynamically to each media stream and schedules Before comparing the weight of each media stream, each time the media stream with the heaviest weight is selected for scheduling, it draws on the advantages of other multi-media stream scheduling algorithms and takes full account of the priority of multi-media stream scheduling. Experimental results show that the algorithm is feasible and effective.
